Underwater Channel, PHY and MAC for NS-MIRACLE

We have developed a module for ns-miracle that allows a fully detailed simulation of the underwater channel, including frequency-dependent attenuation and noise, and the impact of temperature, salinity and depth on the propagation speed of acoustic waves. Included in this model are also two underwater PHY models: one providing the maximum theoretical bitrate according to Shannon's theorem, and the other implementing a BPSK modulation scheme. Other PHY layer implementations can easily be developed. Thanks to the PHY/MAC API included in Miracle, it is possible and also very easy to develop and test different MAC layers on top of the underwater PHY. Currently provided MAC protocols are ALOHA and FDMA. The module can be downloaded here below. Please note that nsmiracle version 1.2.0 or above is required for the module to run.

Model for underwater channel in ns2

We also provide a module that allows simulation of the underwater channel in standard ns2. Please note, however, that this module is not maintained any more, we provide it as-is and without support of any kind.
