Power Electronics for automotive”

Abstract: Automotive environment is very challenging for the electronics modules mounted in a car. According to where they are hosted, the IC should work within a huge range of temperature and should be immune of disturbances coming from the environment as ESD event and EMI, which means they should be very robust. Moreover, depending where the IC is mounted (ie EPS, airbag…), it should also prevent the system to fail and cause injury to passengers.

In this seminar it will presented an overview of the harsh environment where the electronic component is supposed to work with a deeper look of the battery that is the core of the energy storage for the electronic modules in a car. It will be discussed also briefly the quality target the automotive IC normally has to reach.

In addition this tutorial will introduced energy efficient systems that will satisfy the increased demand of CO2 reduction with special focus on power supply modules (standalone linear or switching regulators as well as System Basis Chip solution). Finally the Functional safety will be introduced describing the purpose of the ISO26262 standard and discussing the consequence in the development of the IC from process to technical solution.

Vehicular communications”

Abstract: Vehicular networks have been investigated by industry and academia for over a decade yet no actual deployments are on the road today; this due to inadequate technical solutions and a vertical market that slows down innovation. Recent innovations in autonomous driving, however, are reinforcing the case for connected vehicles able to communicate both V2I and V2V in support of cooperative driving and machine-to-machine information exchange. In this talk we will take a journey through the current state of the art and research challenges in Connected Vehicles. From the initial vision of Ad-Hoc connectivity to the modern vision of an integrated M2M network able to seize connectivity opportunities as well as to take advantage of LTE infrastructure.

Fundamentals and recent advances in vehicle platooning control

Abstract: The objective of this lecture is twofold: 1) introducing the fundamentals and 2) overviewing the most recent results on vehicle platooning control. The lecture is therefore organized in two parts. First, the basics of vehicle dynamics modeling and longitudinal control will be presented to formally state the platooning control problem. The string stability property will be then introduced and two important classes of string stable linear controllers will be presented and analyzed. In the second part of the lecture, recently proposed approaches will be overviewed, with emphasis on the challenges set by the inherent limitations (delays and packets drops) of wireless communication links. Experimental results will be presented, based on a three-vehicle platoon.

parallel digital signal processing in a mW power envelope: how and why?”

Abstract: With the widespread diffusion of distributed and wearable sensors, the requirements for ultra-low power sensor data stream processing and fusion are becoming more stringent. In this talk I will discuss recent trends in near-threshold parallel processing which make it possible to break the pJ/op barrier at a total power envelope of a few mW. In this regime, sensor interfaces become the power bottleneck and new solutions pushing heterogeneous integration are required.

Signal processing: a networking perspective

Abstract: This tutorial will illustrate how signal processing plays a pivotal role in many fields of the networking domain. We will start with a broad overview of the main challenges in modern networks and discuss how signal processing gets into p-lay in this domain. To substantiate the discussion, we will successively consider specific networking challenges that are tackled by adopting suitable signal processing techniques at different levels of the protocol stack. We will show how context-information can be inferred from suitable processing of PHY-layer signals and exploited to improve the high-level network performance, or to support location-dependent services. Then, we will see how signal processing can help designing network protocols in wireless sensor networks. Finally, we will show an example of how signal processing methods coming from (apparently) unrelated areas, such as that of cognitive science, can be applied into our domain for the optimization of modern communication systems.

Signal processing for unconditional security

Abstract: As our personal data and communication are ever more often transmitted and stored in electronic form, concerns are growing about whether we can maintain some control over them and to what extent. Such interest has led to the development of the field of information and communications security well beyond the traditional realm of military communications. In particular, the unconditional security paradigm guarantees a given level of security that is independent of the computational capabilities of the adversary, by leveraging the generation and processing of (true) random signals In this tutorial we will review the application of signal processing techniques in providing several security services, such as secrecy, anonymity, signal authentication and integrity protection, watermarking and fingerprinting, with a particular focus on those mechanisms that ensure unconditional security. Application examples will range from secret wireless communication at the physical layer, to the protection of multimedia content.

Image and video analysis: feature descriptors and their applications

Abstract: This tutorial will cover some recent advancements in the field of image and video analysis. The first part will be devoted to the extraction of relevant features from images and videos like edges, corners and other distinctive points. The construction of reliable descriptors for the points of interest will then be addressed with a particular focus on the Scale-Invariant Feature Transform (SIFT), a method that has attracted a huge interest in recent years. Finally some examples of the usage of the extracted features in applications like image mosaicking, 3D reconstruction and motion estimation in videos will be shown.

Gallium Nitride based sensors

Abstract: The tutorial will cover the latest research in III-V nitride-based sensors for gas, chemical, biological,and medical applications. Wurtzite AlGaN, InGaN and AlInN exhibit a macroscopic non-linear pyroelectric polarization, which dramatically affects the optical and electrical properties of multilayered Al(In)GaN/GaN hetero-, nanostructures and devices. Gradients in polarization cause huge built-in electrostatic fields and bound interface charges at surfaces and heterointerfaces. The corresponding free carrier concentration profiles are very sensitive to any manipulation of surface charge. This physical effect can be used to develop novel sensors for ion fluxes, gases and polar liquids. AlGaN/GaN-heterostructures with polarization induced two dimensional electron gases (2DEG) are used to detect gases, ion fluxes or biomolecules and to determine volume and pH-value of waterbased nano- and picoliter droplets. Direct monitoring of bioreactions by recording of the ion channel activity of cells was demonstrated as well as the application in selective DNA sensors by appropriate surface functionalization. The tutorial features a balance between original theoretical and experimental research in basic physics, device physics, novel materials and device structures, process, and systems. It will begin with a general overview of the basic physics of the devices and the device designs, followed by the current state of the art, new trends, and unique advantages and limitations of this technology.

Sensor networks for industrial applications

Abstract: Distributed architectures for industrial applications are a new opportunity to realize cost-effective, flexible, scalable and reliable systems. Direct interfacing of sensors and actuators to the industrial communication network improves the system performance, because process data and diagnostics can be simultaneously available to many systems and also shared on the Web. However, sensors, especially low-cost ones, cannot use standard communication protocols suitable for computers and PLCs. In fact, sensors typically require a cyclic, isochronous and hard real-time exchange of few data, whereas PCs and PLCs exchange a large amount of data with soft real-time constrains. Looking at the industrial communication systems, this separation is clearly visible: several fieldbuses have been designed for specific sensor application areas, whereas high-level industrial equipments use wired/wireless Ethernet and Internet technologies. Recently, traditional fieldbuses were replaced by Real-Time Ethernet protocols, which are ''extended'' versions of Ethernet that meet real-time operation requirements. Besides, real-time wireless sensor networking seems promising, as demonstrated by the growing research activities. In this paper, an overview of the state-of-art of real-time sensor networks for industrial applications is presented. Particular attention has been paid to the description of methods and instrumentation for performance measurement in this kind of architectures.

Fiber Optic Sensors for Industrial Applications: Perspectives, Challenges and New Trends

Abstract: Over the past two decades,fiber-optic technology has revolutionized the telecommunications industry,enabling high-capacity, long-distance communications and networking at staggeringly low costs. Fiber sensing—the use of fiber optics for industrial sensing applications—is another exciting growth area for this versatile technology.Some ideas indeed have made the leap from the laboratory into the highly competitive market of sensor technology. This transition has taken the better part of 20 years and reached the point where fiber sensors enjoy increased acceptance as well as a wide spread use for structural sensing and monitoring applications in civil engineering,aerospace, marine, oil & gas, composites, smart structures, bio-medical devices, electric power industry and many others. Optical fiber sensor operation and instrumentation have become well understood and developed. And a variety of commercial discrete sensors based on Fabry-Perot (FP) cavities and fiber Bragg gratings (FBGs), as well as distributed sensors based on Raman and Brillouin scattering methods,are readily available along with pertinent interrogation instruments. Among all of these, FBG based sensors—more than any other particular sensor type—have become widely known, researched and popular within and out the photonics community and seen a rise in their utilization and commercial growth. This lecture reviews the major milestones of their technological evolution during the thirty years from the discovery of Kenneth Hill in 1978. Further, the lecture includes an overview of the major developments carried out at University of Sannio aimed to demonstrate the effectiveness of the technology to provide suitable solutions for strategic industrial sectors. The lecture analyses some 'Case Studies' demonstrating how the synergy between research and industrial worlds would open new successful market options.Integration, security, and synchronization aspects

Integration, security, and synchronization aspects

Abstract:   Sensor networks, be they wired or wireless, are often part of a larger network infrastructure. In order to allow for effective transmission of information, such networks must be properly integrated. We discuss integration problems, suitable architectures, and in particular hybrid network concepts supporting seamless real-time capabilities. We also address security issues which are especially demanding in sensor networks due to the potentially large number of nodes, the high degree of distribution, and the inherent resource constraints.

Finally, we will discuss synchronization aspects in distributed sensor systems, their basic operation principles, ways to improve synchronization accuracy, and applications or services that can be built upon precise synchronization, such as localization of wireless nodes.

Networked control and autonomy

Abstract: Networked control systems have sensors and actuators connected through wireless communication networks. These systems are of growing importance in many engineering domains. In these two lectures, we will first motivate networked control from recent developments in sensor networking, wireless communication, and real-time control, which have enabled more autonomous, efficient, and robust control systems. Illustrated by research projects with Swedish industry, some of the practical challenges will be discussed. In the second lecture, we will formalize these challenges into research problems and discuss how to systematically design and implement networked control systems. The interplay between the requirements from the control application and the uncertainty of the underlying wireless medium will be highlighted, for example, how the wireless access scheme can drastically influence the networked control performance. It will be argued that the underlying scheduling-control problem has an interesting non-classical information structure. Appropriate models for medium access control protocols will be introduced. It will be shown how these protocols can be tuned for various wireless control applications. We will also see that by making event-triggered transmissions based on decisions taken locally at the sensor and actuator nodes, it is possible improve the design and to limit the use of the communication resources.

Self-assembling sensor networks
Abstract:   Self-assembling nano-structures have already been investigated for a number of years in various classical disciplines like physics, chemistry, and biology, but research has mostly focused on rather simple particles without intelligence like DNA molecules. In recent years, also self-assembling structures based on intelligent particles have been investigated, particularly in the context of modular robotics. Self-assembling nano-stuctures have a number of very interesting applications, especially in medical treatment and environmental monitoring. An important problem in the second texts is the so-called smart paint problem: Given a certain object O and particle structure S that is connected to O, design a simple distributed protocol for the particles that allows them to transform their structure in order to cover O as good as possible without losing connectivity at any point in time. In my talk I will discuss particle models and ways of solving the smart paint problem and show how this can help to solve certain monitoring problems.

Glucose Sensor Smarter for Managing Diabetes:Where We Are and Where to Go.

Abstract. Tight monitoring of glucose concentration in the blood is essential in the management of diabetes, a pathology which affects 350 millions of people in the world. Since the early 2000’s, portable and minimally-invasive continuous glucose monitoring (CGM) sensors have been proposed in the market to measure glucose concentration in real time with a 1-5 min sampling period and for up to7 consecutive days. These CGM sensors are potentially usable in applications of great clinical impact, as on-line prediction of forthcoming dangerous hypo/hyperglycemic events and artificial pancreas algorithms for closed-loop glucose control, but some accuracy and precision problems of the state-of-art devices are still open. In this lecture we present some on-line signal processing algorithms that we have developed in the recent past to render glucose sensors “smarter”. In addition, we describe progresses and perspectives of our recently established collaboration with Dexcom Inc., one of the world's leading glucose sensors manufacturers, aimed at porting some of our algorithms within a commercial CGM device.

Energy harvesting wireless sensor networks

Abstract:   Lifetime of wireless sensor networks depends critically on the energy available at individual sensor nodes. However, constraints on the cost and physical size of low-complexity sensor nodes severely limit the battery capacity. Moreover, battery replacement can be impractical or impossible due to inaccessibility of remote sensor nodes, or their vast numbers. Harvesting the available ambient energy is a promising technology for sensor networks providing theoretically perpetual operation. However, in most cases harvested energy is limited in quantity and sporadic in availability, necessitating novel communication schemes to best exploit this intermittent energy. In this lecture we will study the design of intelligent communication schemes for energy harvesting sensor nodes. Focusing on a point-to-point time-varying channel, we will consider stochastic arrival of both energy and data over time, and take into consideration practical system parameters such as battery leakage and energy consumed in the processing circuitry. We will identify the optimal transmission schemes in the 'offline optimization' framework, which assumes non-causal knowledge of all future events in the system; as well as in the 'online optimization' framework, assuming only a statistical knowledge about the underlying random processes. Finally, we will provide a 'learning-theoretic' approach, suitable for practical scenarios in which the statistical properties of the underlying random processes are either not known at the deployment, or vary over time. If time permits, we will also consider challenges in designing communication protocols for networks of energy harvesting nodes.

Workshop: “WSAN: Wireless sensor and actuator networks”

Overview of Power Processing Techniques for Harvesting-Based Wireless Sensor Nodes

Abstract: The broad range of potential applications of Wireless Sensor Networks (WSN’s) is drawing attention from many and interdisciplinary research fields, encompassing telecommunications, control theory and low-power electronics. Crucial to the practical utilization of large-scale WSN's is the sensors capability to operate over extended periods of time in an essentially zero-maintenance fashion. Such energy autonomy is a key requirement for large-scale WSN’s, in which tens to hundreds of sensor nodes are scattered over the environment. Scenarios include industrial monitoring, building automation and surveillance systems, and even more challenging outdoor applications such as landslide detection networks, in which sensor nodes may no longer be accessible once deployed. For the above reasons, conventional sensor nodes powered by non-rechargeable batteries are evolving into harvesting-based sensor nodes capable of absorbing ambient energy and locally storing it into an on-board rechargeable cell. Because of the very nature of harvesting-based nodes, smart power processing and battery management solutions are mandatory for effective utilization of the available energy and prolonged sensor lifetime. The talk first provides a preliminary overview of available energy sources and power processing techniques for harvesting-based wireless sensor nodes. The presentation then outlines recent and ongoing activities of the Power Electronics Group in the energy harvesting field.

Design and characterization of sensor nodes under real constraints

Abstract: The growing interest on Wireless Sensor and Actuator Networks (WSAN) in these last years is mainly due to the benefits that such kind of distributed measurement and control systems present. WSANs represents a winner technology in situations where a wired communication infrastructure results to be excessively demanding in terms of accessibility, feasibility and maintainability costs or it results even impossible to realize. Furthermore, in this context network nodes must be necessarily fed up by autonomous energy sources, such as batteries or energy harvesting modules and, on the other hand, they must be designed in order to consume few energy resources. Finally, WSANs, as well as any distributed measurement system, must also rely on a common timescale that needs to be shared among its constituent elements. In this talk we will illustrate the comprehensive structure of a sensor node by describing the main functionalities and characteristics of its constituent elements such as the measurement block, the power management unit, the communication interface, the clock module and the elaboration unit. The attention will be focused in particular on the clock module and synchronization systems, which represent a crucial issue in measurement applications.

Modeling and Optimizing the Operation Policies of Energy Harvesting Devices under Realistic Assumptions

Abstract: Battery-powered devices are subject to limitations in their energy storage. Such a constraint is often simply represented as if the devices had an energy bucket'' which can be emptied but not replenished. Energy harvesting capabilities change this rationale by allowing the energy storage part to become more similar to a buffer, which could be studied within a queueing system context. A communication device, e.g., a wireless sensor node, is therefore characterized by an energy queue, which must be coordinated with the data queue it has to transmit. Yet, several assumptions should be included in the representation of the energy queue in order to have a meaningful approach. For example, not only the discharge process of the battery is correlated, as it happens in batches due to transmission of packets from the data queue, but also the arrival instants of energy in the battery cannot be independent. Moreover, a precise evaluation of the exact level of charge in the battery is difficult, as it is both time- and also energy-consuming. This talk will discuss the challenges in properly modeling such a system, showing how oversimplified models can lead to system underutilization and/or inefficiency. Conversely, we will also show how, under proper conditions, even a small amount of information on the battery charge status can be extremely helpful in achieving an almost-optimal performance.

Smart micro-grids - Properties, trends and local control of energy sources.
Abstract. After a general introduction of the main properties, benefits and challenges of the smart grid, the lecture focuses on low-voltage residential smart grids (smart micro-grids), which represent a new and huge potential market for ICT. In fact, the distributed energy resources acting in the micro-grids (renewable sources, storage batteries, etc.) interface with the distribution network by electronic power processors (EPP), whose synergistic operation may result in full exploitation of energy sources, increase of distribution efficiency and voltage stabilization across the micro-grid. This requires distributed cooperative control algorithms, which are implemented locally in each EPP and feature plug & play operation. The lecture analyzes some basic cooperative control principles which allow automatic integration of new energy resources, provide quasi-optimum operation of the micro-grid, and require only narrowband communication among neighbor units.

RF building blocks and techniques for low power wireless transceiver
Abstract. The reduction of power consumption in modern wireless transceivers can be achieved following two main strategies: the power recycling and the power re-configurability. In the first case, a long-lasting battery life is obtained with a penalty in performances while in the second case with an increment of the complexity. Both these approaches will be discussed: current re-use techniques applied to GPS and WSN receivers, while power scalability concept applied to some RF blocks of a cellular transceiver.

Distributed Control of the reactive power in smart microgrids.
Abstract. We consider the problem of optimal reactive power compensation for the minimization of power distribution losses in a smart microgrid. We first propose an approximate model for the power distribution network, which allows us to cast the problem into the class of convex quadratic, linearly constrained, optimization problems. We also show how this model provides the tools for a distributed approach, in which agents have a partial knowledge of the problem parameters and state, and can only perform local measurements. Then, we design a randomized, gossip-like optimization algorithm, providing conditions for convergence together with an analytical characterization of the convergence speed.

Power Line Communication Systems in the Smart Grid Context
Abstract. The seminar will focus on Power Line Communication (PLC) Systems: telecommunication systems that are among the most interesting in the Smart Grid context. PLC systems exploit the electrical wires to convey information data. This can translate into reduced installation time and cost for the telecommunication infrastructure that is necessary for the management of the grid through supervision and control mechanisms. The seminar will offer an overview of PLC applications. Then, we will discuss relevant aspects related to the channel characterization, channel modeling, and we will describe reliable transmission technologies and techniques. Finally, we will present some relevant PLC standards, both narrow band and broad band, and discuss their application in the Smart Grid.

Smart Grid Communications in Rural Areas --- Wireless Access via TV White Space Spectrum
Abstract. Due to the hierarchical organisation of the electricity grid and the emergence of distributed generation particularly in rural areas where the communications infrastructure is poor, this seminar will focus on emerging wireless access techniques for areas which are currently underdeveloped or underserved. As an example, we will focus on a wireless trial running in the Western Isles of Scotland, where broadband access and 3G services are non-existent or limited at best. We will review the emerging idea of utilising 'white space' spectrum, which is being freed as part of the switch-over from analoue to digital TV broadcast. The freed UHF spectrum has benign propagation characteristics, and a comparison between wireless broadband access in UHF to 2.4GHz and 5.2GHz bands will be made. Results from the trial will be presented, and motivate novel transceiver designs that are capable of sampling at RF, have cognitive features and can interact with geolocation data bases in order to identify suitable transmission channels. The seminar will conclude by considering how TV white space communications can be best utilised to enable smart grid communications.

Advanced devices for efficient power conversion for green applications
Abstract. Green applications have entered the news not only since the recent natural disasters. They have also changed our way of considering every modern commodity. Electronic power devices and circuits are the engines of this technical development which is steady, breathtaking, and still - progressing extremely dynamically. The tutorial will give an overview on electronic devices for power applications with a focus on the developments induced by recent progress in the wideband gap semiconductor world. This includes the discussion of trends such as higher conversion frequencies, more compact designs, and faster switching and related issues.

The tutorial will be divided in three parts: in a first part it discusses material properties of group III-nitride semiconductors for power applications. In a second part advanced power devices and circuits are given for both group III-N as well as silicon technology including, e.g., FET, COOLMOS and IGBTs. The third part yields a mutual comparison and circuit examples are given for various green applications.

Future Trends in Zero-Power Systems
Abstract. Zero-Power systems may contribute to many applications in various sectors. Among them portable autonomous systems could open new endemic scenarios for wireless sensor networks, in situ monitoring for mobile/moving systems, body area networks, biomedical devices, portable power generation for mobile electronics. Special attention has been given to the market drivers for adopting energy harvesting devices in different market segments, factoring the progress of competing technologies and cost constraints. This presentation is aimed at giving an overview of this emerging field where energy aware electronic design is of strategic importance. However, since the processes of scavenging, transforming and storing energy are strictly inter-dependent, design optimization procedures should be treated using an integrated approach from a system perspective.

Wireless Technology for autonomic networks
Abstract. Traditional telecommunication systems were designed for a single technology, while the modern communication infrastructure builds on a suite of technologies, devices, equipment, facilities, networks and applications for support of communication at a distance, often without human intervention. Each communication element (e.g., device, service, application) uses a mobile radio component for communicating data by way of some specific technology. Communication scenarios in the context of modern telecommunication systems are defined by the data context and can occur randomly among mobile components based on different technologies (i.e., heterogeneous), leading to an unpredictable and complex communication process and dynamic network topology. Reliable end-to-end transfer of data to application, which provides the particular network functionality and interface to the user, depends on algorithms and protocols for medium access control, routing, and mobility. Currently, these are organized in layers in architecture known as protocol stack and need the cooperation of a set of complimentary layered capabilities. The layered design is a key limitation as it assigns each protocol layer a specific purpose and task to support the data transfer, and is executed by means of targeted design protocols associated with it.

The tutorial will provide a good understanding in the fundamental principles on which modern telecommunication systems build and will outline the reserach challenges and approaches to overcome those for their successful adoption.

Renewable Energy Sources for Distributed Generation in Smart Grids: the role of Power Electronics
Abstract. The continuously increasing demand of energy, the reduction of the availability of traditional energy sources (oil, gas, nuclear, etc.) together with the increasing concern about environmental conditions (pollution), have risen the interest on renewable energy sources (wind, solar, thermal etc.) that are almost democratically distributed, with different concentration levels, on the whole earth surface. This fact is going to affect the way how the energy is first generated and then distributed in large areas and is likely to drastically change the traditional energy distribution grid into the so called 'smart grid', where few power sources of large capacity and sinusoidal supply are replaced by many small, distributed and interacting energy sources providing supply voltages that can be asymmetrical and distorted. From the above considerations, it follows that facing the problems of smart grids requires a revision of traditional power theories as well as a comprehensive approach to cooperative operation of distributed electronic power processors.

The seminar is divided into two parts: in the first one, after a brief discussion of the potentialities and challenges of smart grids, the focus will be on the role and the requirements of power electronic converters interfacing energy sources, like photovoltaic panels and fuel-cells, with the grid. In the second part, it is shown why traditional power theories are no longer able to model the scenario opened by the smart grid paradigm and a new conservative power theory is introduced, that can be used for reducing power consumption from the utility, improving power quality and increasing distribution efficiency.

On the applications of factor graphs and the sum-product algorithm to detection and decoding
Abstract. Many detection and decoding problems can be formalized as the computation of the marginal distributions associated to a joint probability mass function (pmf) or to a joint probability density function (pdf) of many variables. Factor graphs (FGs) are a graphical representation of these joint pmfs or pdfs describing how these functions may be factorized in the product of 'local' functions, each of which depends on a subset of the variables. These factor graphs enable efficient computation of the marginal distributions through thesum-product algorithm (SPA). Although proposed to explain decoding algorithms for capacity-approaching error-correcting codes, such as low-density parity-check (LDPC) codes and turbo codes, FG and SPA have proven to be very useful in deriving new detection/decoding algorithms with unprecedented performance/complexity trade-offs.

Detailed program

Opportunities, technologies and challenges in the Internet of Things
Abstract. The Internet of Things (IoT) is a novel paradigm that is rapidly gaining ground in the scenario of modern wireless telecommunications. The basic assumption of this concept is the pervasive presence around us of a variety of things or objects – such as Radio-Frequency IDentification (RFID) tags, sensors, actuators, mobile phones, etc. – which, through unique addressing schemes, are able to interact with each other and cooperate with their neighbors to reach common goals.
The IoT has the potential to radically change our life, even more that what the Internet did so far.
However, there are several conceptual and technical challenges that must be faced before the IoT can be actually realized and there is huge space for basic and applied research in most fields of information engineering and science. For example, the IoT requires novel addressing schemes that can be used by heterogeneous technologies, there is the need for technical solutions able to guarantee an acceptable level of security and privacy, new mobility management solutions are required able to cope with the huge number of objects that will be included in the IoT, appropriate traffic characterization and modeling is needed to evaluate the impact of the deployment of the Internet of Things on the communication infrastructure, and scalable service discovery protocols are also required that operate efficiently in extremely large networks, and this list could continue further and further.

Objectives of this course are manyfold as we will:
• Introduce the fundamental concepts, technologies and standards related to the Internet of Things
• Survey the basic architectural and technological approaches proposed so far
• Provide the most relevant open research challenges regarding the Internet of Things

Quantum cryptography: when security comes from uncertainty
Abstract.In the modern approach to cryptography, the security of network and communication protocols heavily relies only on the confidentiality of the keys to cryptographic algorithms that must be shared between transmitter and receiver, often without the use of a separate secure channel. The importance of reliable and secure schemes for key distribution or agreement is therefore easily understood.

Quantum key distribution (QKD, popularly known as Quantum cryptography) represents the only practical instance of perfect secrecy, in the information-theoretic sense, that has been so far accomplished. Its security relies, on one side, on the laws of quantum mechanics such as the uncertainty principle or the no-cloning theorem, on the other on information-theoretic methods for the processing of common randomness.

In this tutorial talk, after introducing motivations and requirements for QKD, I will briefly review the information-theoretic model and the theoretical limits on the generation onf perfectly secure keys. Then, I will present under a common established framework the different practical schemes that are currently adopted in QKD implementations, and discuss methods and possibilities for the integration of QKD into commodity security protocols at different layers of the OSI stack. Finally I will identify current and future research directions and open problems.

No previous knowledge of quantum mechanics is required to the audience, just some basic notions of information theory (entropy, mutual information, source and channel coding).

Prof. Giorgio Matteo Vitetta,University of Modena & Reggio Emilia and CNIT, Game Theory: Application to Communication Systems

Abstract: In a human community, the goal of each member is to satisfy its own needs through the available environmental resources. Similarly, in a wireless communication network, the terminal of any user tries to satisfy its own requirements, in terms of connectivity, exploiting the resources it is endowed with. Such resources, however, are limited and, at least in part, need to be shared with other users; their physiological shortage raises the problem of establishing fair rules that regulate the sharing among multiple users, each having its own personal goals. This natural similarity between the problem of resource management in a communication system and that of the resource management in a complex social system suggests to adapt the methods, exploited for a long time by economists to tackle the latter problem, to solve the former one. One of the most relevant theoretical methods in this area is probably the so called game theory, which represents a powerful tool to model and solve the above mentioned problems. In this talk, after illustrating some basic concepts of game theory, some of its applications to data communications in wireless ad hoc networks are analysed. In particular, we focus on the problem of coordinating data communications among multiple terminals (acting as data relays), so that reliable multi-hop links can be established.

With such a diversified lineup of computing resources, the choice of which resource is better suited for each component in the telecommunication system is far from trivial.This is the first of a series of two talks illustrating an example of hardware/ software partitioning for the implementation of a DVB-T2 transmitter on a board with an ARM GPP, a C64x+ DSP and a Virtex4 FPGA.

Abstract: 100 Gigabit Ethernet is actually demanding for next generation optical networks. Since the transition between 1 to 10 GbE mainly involves cost and power consumption reduction, the jump toward 100GbE must take care of physical, technological and transmission issues. Electronic components and ICs are pushed to their limitation in terms of bandwidth and power requirement and, at the same time, optics are still in their early stage. Novel material, techniques and approaches must be reviewed in order to understand real 100 GbE perspectives. Within such framework, the state of the art for 100 Gbit/s transponder will be analysed and their suitability for 100 GbE discussed. At the same time, different technological solution including Electrical Time Division Multiplexing (ETDM), Wavelength Division Multiplexing (WDM), Optical Time Division Multiplexing (OTDM), and Polarization Division Mutiplexing (PDM) will be addressed in single and hybrid configuration. Modulation formats will be also considered together with transmission impairments as a function of the link characteristics.

Finally latest experimental results will be reviewed, compared, and discussed.

dr. Antonella Bogoni, CNIT, 'DIGITAL PHOTONIC PROCESSING FOR NEXT GENERATION HIGH CAPACITY OPTICAL NETWORKS AND OPTICAL COMPUTING'

Abstract: In the last two decades the telecom transport market has experienced the evolution from the “digital electro-optic” to the “analog photonic” technology. It is very likely that the next decade will see the transition from the “analog photonic” to the “digital photonic”, in which a ultra-high bit-rate telecom signal will be processed at very low cost preserving the features of scalability in bit-rate and wavelengths which were brought in by analog photonics, meanwhile providing the necessary immunity from noise and transmission impairments which are typical of digital systems. Photonic digital processing of high speed optical signals will also open new applications where fast computation speed is required as in the field of optical interconnect inside mainframes, in clusters of servers inside data rooms and in applications of cloud computing among remotely located servers, with advantages in terms of throughput, wiring density, latency, and power consumption. Even if appropriate technologies are not yet mature enough, a feasibility demonstration of the digital photonic processing potential is mandatory to drive the future technology evolution. Here we will present recent results at the leading edge in the international scenario, on the realization of the basic blocks of photonic digital processing as all-optical logic gates, switches and flip-flops and more complex subsystems enabled by such basic blocks, as optical combinatorial networks to carry out full addition, comparison, counting, analog-to-digital and digital-to-analog conversion. The reported implementations are based on semiconductor and waveguide devices here considered as possible technological choices due to their integrability, and stability features.

Joint Routing and Scheduling in Wireless Mesh Networks
Abstract:Wireless Mesh Networks are multi-hop networks which provide wireless connectivity between clients and the Internet through dedicated router platforms. The clients can be mobile, but the routers are usually stationary. A strong advantage of this network architecture is to be cost-effective, since cable deployment is not required. Therefore, mesh networks are particularly suitable for wide rural areas as well as office and home environments.
To effectively provide broadband connectivity, several technical issues must be addressed for mesh networking. Much of these issues involve multi-hop wireless communication. In particular, a deeply studied but also challenging problem involves the search for a cross-layer approach between scheduling and routing, so as to realize a Joint Routing and Scheduling (JRS) framework.
In this presentation, we will outline general principles of wireless mesh networking, with particular emphasis on theoretical and algorithmic aspects. Moreover, we will discuss in detail the JRS problem, for which we will review and discuss several approaches, involving various methodologies and technical factors. A significant part of the lecture will be dedicated to identifying ongoing research directions and open paths for future investigations.

Multicanonical simulation techniques and their relation to importance sampling
Abstract: This short course will provide a tutorial introduction to the Multicanonical Monte Carlo (MMC) method, introduced by physicists Berg and Neuhaus in 1992. MMC is a truly innovative simulation technique used to estimate the probability density function (PDF) of a desired system output (scalar) variable, given the (known) PDF of the system (multidimensional) input. For example, in digital communications, the output variable can be the decision variable at the sampler, while the system random input is the ensemble of all noise samples accumulated along the transmission line, and of the random bits in the transmitted sequence that cooperate to set the value of the decision variable. The method is based on an adaptive Importance Sampling (IS) procedure, and does not need any special prior knowledge of the physical system at hand in order to find a good biasing input distribution, which is the true limit of fixed IS.

Security in Wide-Area Wireless Networks: theory, practice and open issues
Abstract: Network security, besides the clear importance of the topic in the context of contemporary telecommunication networks, represents a source of several inter-disciplinary research subjects. The integration of security mechanisms in telecommunication networks requires coordinated efforts from many directions during the research, development and deployment phases. This becomes even more important when considering wide-area wireless networks, because of their considerable user base and the very stringent requirements they are subject to, such as minimal handover latency, for example.
This seminar will introduce the state of the art and main research directions for network security, with specific references to mobile networks. We will introduce the basics of network security, including topics such as efficient user and terminal authentication, the protection of privacy both for user data and for signaling and briefly touching on issues such as Intrusion Detection. We will then analyze how these issues have had an impact on the design of modern wireless networks, such as GSM, UMTS and 802.11, and how they are shaping the modeling of future mobile networks.

Image-Based Rendering Methods
Abstract: In Image-Based Rendering (IBR), images of a real scene are taken from various view points and novel views of the same scene are synthesized from a virtual camera by processing the real images, without the need of a full three-dimensional reconstruction. I will first introduce basic geometric concepts and algorithms on multiple-view analysis, including epipolar geometry and plane+parallax theory. I will then move to the problem of computing correspondences (or disparity) in two and more views. Disparity plays an important role in image-based rendering as a proxy for the scene geometry. Finally I will give an overview of previous work on image synthesis from real images. Different techniques are described for synthesizing novel views from real images and video streams. Throughout, the presentation will try to focus on aspects of IBR relevant for 3-D image communications.

Fotorivelatori avanzati basati su diodi a valanga a singolo fotone per visione 3D e imaging medico
Abstract: In this lecture, after recalling some basic concepts about light interaction with silicon, a new generation of photodetectors will be introduced, based on Single Photon Avalanche Diodes (SPAD). Although the invention of this device dates back to the 60’s, only recently its feasibility in standard CMOS technologies has been demonstrated, a fact that has opened the way to the fabrication of 1-d and 2-d arrays with integrated electronics. The same device concept, but with a full custom fabrication technology, is expoited in silicon photomultipliers (SiPMs), which consist in a 2-d array of SPADs with integrated quenching resistors in series, having all their terminals connected in parallel, so as to obtain an analog behavior starting from an intrinsically digital device (the output signal is proportional to the number of single pixels hit by a photon). Both SPAD arrays and SiPMs lend themselves to very interesting application opportunities in several fields: among them, luminescence microscopy, fluorescence decay analysis, optical testing of high speed circuits, range measurements (3d vision) and medical imaging.

Prof. Giorgio Franceschetti, University Federico II of Napoli, Italy and UCLA, USA, 'An overall vision of electromagnetic propagation in built-up areas'
Abstract: Propagation in the urban environment is in principle a well-posed problem: the electromagnetic field radiated by prescribed sources must fulfil Maxwell equations in the open space and boundary conditions over the built-up buildings walls. But any attempt to provide a solution to this apparently simple problem must face the complication of the scattering scenario. Each city is different from any other city, type and distribution of buildings may drastically change among different sections of the same city, and the electromagnetic boundary conditions may change in time, because the city is a living organism, with its cycles and temporal variations. A general frame to locate above mentioned problem is certainly desirable, if not necessary. The cities’ distribution may be considered as a stochastic process, each city being an element of this ensemble. Accordingly, the study of electromagnetic propagation and scattering in the city becomes the problem of searching the solution of Maxwell equations in a stochastic environment. This task may be pursued on along essentially two lines of thought: either a deterministic or a stochastic one. The former makes reference to an element of the ensemble, the latter exploits the statistical properties of the distribution. In the first case, the Deterministic Geometrical Model (DGM), an element of the cities’ ensemble is chosen, namely the particular city of interest. Knowledge of the three-dimensional geometry of the city must be known, i.e., shape and location of each building. These are schematised in terms of a parallepipedic structures, and ray tracing procedures are implemented to compute the electromagnetic field everywhere outside, i.e., in the streets and squares of the city, and perhaps also inside the buildings. In the second case, the Stochastic Environment Model (SEM), a totally different philosophy is followed: aim of the model is to derive general analytical expressions, describing the average properties of the urban propagation. In addition, the analytical results are required to containing a minimum number of physically meaningful parameters. An interesting model for the cities’ stochastic distribution is the percolative lattice: a two dimensional regular lattice of rectangular sites, where each site may be empty with probability p or occupied with probability q=1-p. The attractive feature of this model is the imprinting of the city structure in the city probabilistic description. This presentation highlights merits and limitations of the two approaches. For the DGM a numerical code is discussed, and examples of computations are critically shown, as well as possible extensions of the software. For the SEM analytical results are presented, leading to interesting theoretical considerations. In both cases, some experimental results are referred, too. Alternative models worth of future exploration are suggested.

Prof. Gabriella Olmo, Polythechnic University of Torino, Italy: 'Multiple description coding of visual data'
Abstract: Multiple description coding is recognized to be an effective tool for resilient transmission of multimedia data over networks subject to packet erasures. The basic principle is to split the data into multiple streams, or descriptions, which can be independently decoded and yield independent contribution to the quality of the recovered signal. In this tutorial, the most popular MDC techniques for image and video data are described, and the related pros and cons are discussed and compared with single description and layered coding. Particular attention is devoted to MDC compatible with the JPEG 2000 and H.264/AVC standard co-decoders.

9:00-12:30, Tutorial Session
Prof. Marco Lops, University of Cassino, Italy: 'Finite Random Set Theory: a Natural Framework for Multi-User Communications'
Abstract In a typical multiple-access communications scenario, the number of active users, their location, as well as the parameters that characterize their channels vary with time . Thus techniques aimed at identifying not only the transmitted data, but also the users parameter play a central role in analysis and design of wireless transmission systems. Examples of applications e.g., in Multi-User Detection, spatial multiplex schemes and ad hoc networks. 1)MUD receivers must account for the number of interferers being active at any given time. Adaptive systems, wherein the channel is first sensed, and the receiver then adjusted to the real scenario have been proposed, e.g., in [1], while more and more sophisticated procedures have been analyzed in [2-3], in order to deal with more and more challenging scenario. 2)In spatial multiplexing schemes, the total system throughput may be optimized by identifying a subset of users to which the power is allocated (see e.g. [4]). 3)In ad hoc networks, optimal transmission strategies require the identification of active nodes in the neighbourhood of the transmitter.
In this talk, considering, as a field of application, adaptive MUD, the issue of joint identification and parameter estimation of active users is re-formulated in a completely different context, the so-called Finite Random Sets Theory (FRST). To fix the ideas, assume that a classical CDMA system, and denote by N the maximum user number. Assuming a constant load in the network (e.g., K <= N active users) is definitely unrealistic, since it may happen that some of the users become silent at a the end of a transmission phase, while some other users start transmitting. Since each user is characterized by a flag, containing its identity (an integer number <= N), an information symbol, plus a number of unknown parameters (e.g., average power, phase, and so on), the set Xt of users active at time “t” is random, not only in its cardinality, but also in its elements, each element being a members of a hybrid space, S say, the Cartesian product between a countable set U and the space R^d. Additionally, denoting by S_t the random set of the users surviving into epoch t+1 and by N_t the set of newly born users, it is understood that: X_{t+1}=S_t U N_t. Just to give an idea, being able to estimate (possibly in a recursive way) the set sequence {X_t} would enable undertaking channel sensing and user demodulation in a unique step, and would offer the possibility of accounting for a number of effects, such as the users’ activity factor, the inherent death-and-birth process of the users themselves, and so on. To this end, several intermediate steps should be taken, i.e.: Develop a suitable probability space so that “set probability densities” can be defined; Devise manageable models for the evolution of the random set Xt under diverse instances of channel state information; Derive and implement structures which optimally solve the detection/estimation problem above.
The course develops, obviously in a tutorial form, the three points above, and is mainly intended to introducing FRST as a tool whose applicability appears to reach well beyond the issue of adaptive multi-user detection. A tentative schedule might be as follows: Review of classical adaptive multi-user detection [1-3] and reformulation in terms of random sets, with a brief history of FRST: 1 hour; Finite Random Set Statistics: belief functions, set densities, set derivatives, set integrals, set estimation [5]: 1 hour; Multi-User Detection in a Static Channel; Multi-User Detection in a dynamic Channel: set sequence detectors and Bayes Recursions [6-7]: 1 hour; Conclusions and hints for further developments: 0.5 hours.

Abstract: This tutorial addresses the evolution of micro- and nano-electronics technology towards increasing integration levels. First, the functional requirements of CMOS logic gates are briefly summarized, and the main tradeoffs for performance optimization are discussed within the constraints posed by noise immunity and power dissipation. Next, the generalized scaling laws are derived and the fundamental scaling limits of semiconductor devices are discussed, with special emphasis on static and dynamic power dissipation. New device architectures, such as double-gate (DG) and nano-wire (NW) FETs are then illustrated, to alleviate the short-channel effect and improve the overall device performance. Next, the growing problems of interconnect-related gate delay and noise immunity are addressed along with system-level aspects. Finally, device modeling issues are addressed, with special attention devoted to the coupled Schrödinger-Poisson equations and to the required transport models, such as the quantum drift-diffusion (QDD) and quantum-ballistic (QB) models.

Prof. Giuseppe Bianchi, University of Rome 'Tor Vergata', Italy, 'Performance analysis of 802.11 wireless LAN networks'
Abstract: Performance analysis of 802.11 (CSMA/CA) wireless LAN networks has envisioned a renewed and extensive research interest in the last few years. Traditional modelling methodologies, developed in the 70s and 80s were bound to special assumptions, such as, e.g. slotted operation, and/or colliding traffic modeled as a Poisson process, which somehow limited their practical application. Conversely, modern analytical models have been shown to be able to accurately account for important implementation details such as the specific Binary Exponential Backoff rules employed in the practical implementation of CSMA/CA (namely, the Distributed Coordination Function - DCF - of the IEEE 802.11 standard). Goal of this talk is to review the basic foundations and principles of these new modeling methodologies, and to show how they have been successfully applied not only to model single-cell networks, but also how they have been generalized to capture and thoroughly explain critical issues such as lack of fairness and flow starvation emerging in multi-hop/Mesh environments. Rather than providing a report on this research area, the talk wishes to provide an understanding of the basic key ideas, principles, and methodologies which, we believe, are not bounded to the specific framework of Wireless LAN systems, but may be successfully applied to other systems and protocols.
Detailed outline of the talk: - Introduction, review of 802.11 DCF, basic modeling principles - Throughput bounds for 802.11 networks - Markov-Chain saturation throughput analysis and its reinterpretation/generalization in terms of elementary probability theory - Model extensions for error-prone channels and non saturated conditions - Models for multi-hop networks

Prof. Witold Krzymien, University of Alberta, Canada: 'Techniques for high throughput wireless packet data access'
Abstract: In delay-tolerant wireless packet-data applications, throughput can be maximized by exploiting multiuser diversity through scheduling of packet transmissions only to a user (or users) experiencing the (absolutely or relatively) best propagation conditions. To utilize the available channel capacity suitable scheduling algorithms are combined with link adaptation. Advanced hybrid ARQ techniques using soft packet combining and incremental redundancy are used to compensate for errors in channel estimation and feedback transmission. Further gains in spectral efficiency can be achieved by using multi-carrier transmission (OFDM or spread spectrum OFDM). The multi-carrier approach allows for more effective two-dimensional scheduling. The application of multiple antennas results in further capacity gains achievable through spatial multiplexing. It will be demonstrated that gains due to spatial multiplexing can be combined with those due to multiuser diversity, if suitable scheduling is applied. The talk will discuss transmission strategies and scheduling options for single-antenna single-carrier systems, single-antenna multi-carrier systems and multiple antenna single-carrier systems. Theoretical bounds on performance, as well as performance results for specific example cases will be presented. Fundamental differences between transmission and scheduling strategies for single and multiple antenna systems will be exposed.

Prof. Christian Schlegel, University of Alberta, Canada: 'Analog methods for iterative decoding'
Abstract: Iterative decoding of error control codes has become very popular with the invention of turbo codes and their iterative decoding algorithms. The implementation of iterative decoders for both turbo codes as well as low-density parity-check codes is very complex, with digital VLSI circuits requiring millions of gates, even for moderate sized codes. As the speed of digital transmission systems increases, so does the power consumption of the decoding algorithms. Analog decoding is a novel methodology which relies on analog current multipliers that can be realized with very efficient Gilbert multiplier cells. It has been actively researched over the last few years as an alternative to digital implementations and holds the potential of significantly reducing the power requirements, as well as the VLSI footprint of a decoder circuit. In this seminar, we will review the importance of error control coding, and the functionality of low-density parity-check codes as well as the basics of iterative decoding. We will then present the basic principles of carrying out the decoding functions with analog circuits and present state-of-the art results in this novel area.

Abstract The ability of organic semiconductors to obtain decent mobilities has enabled the usage of organic devices, such as transistors. However, the physics of the transport in these materials are substantially different from the transport in classical semiconductor materials. These differences will be discussed and the consequences on devices and applications will be shown. Next, I will detail the growth conditions to obtain high-quality thin films of these organic semiconductors. This high-quality thin-film growth is one of the enablers for the practical devices. Finally, three application areas for organic devices will be discussed, i.e. large area flexible electronics, low-cost printed RF-ID tags, and organic memories for mass-storage.

Abstract: The merge of IP technology paves the way for the next generation network (NGN). For years, network operators and equipement vendors have viewed the coming together of fixed and mobile networks - 'fixed-mobile convergence' for short - as the next step for the telecom industry. However, the industrie's interest in the convergence has changed, from running one network to save money, to giving users acccess to fixed and mobile communication via the same interface. Then, where does the convergence take place? In terminals, access network, core network or service metwork? Which are the standard bodies concerned with fixed-mobile convergence? Whose interest does each of these organizations represent? What are the key technologies behind the convergence? Why do we say Skype is the most disruptive technology? How do we build a seccussful business model for NGN? What is the impact of NGN on our economy?
