A de-centralized multi-static sonar relying on an underwater acoustic network

In this project an acoustic network is studied to reduce the data transmission requirement in a multi-static sonar network. A cross-layer communication architecture is proposed to optimize the acoustic network performance. Using this technique, the network will be informed with the physical conditions of the link to optimize the overall reliability of the data transfer. To establish a reliable network, a first objective consists in defining a modulation technique to establish a point-to-point link between sonobuoys. A second objective of this project is to define a network protocol so that the remote nodes can share the spectrum. To establish the network topology and spectrum sharing, transmitter nodes are expected to have some limited knowledge of the channel conditions. Using this information, the physical layer and routing protocol will be configured accordingly to optimize the network reliability.
