A Self Adaptive MAC layer and Routing Layer framework for delay-tolerent underwater wireless sensor networks

Nearly 70% of the earth is surrounded by water; hence it is appropriate to use underwater sensor networks to enable oceanographic research. In case of UWSN radio waves are not suitable for communication as propagation capability of radio waves is very poor in under water. Hence UWSN uses acoustic signals for communication. The transmission speed of acoustic wave is less than the transmission speed of radio wave due to various physical parameters of underwater acoustic channel. Hence the throughput of the channel is affected by this large delay. The long and uncertain delay makes many classical protocols unsatisfactory because they depend on multiple handshakes and appropriate calculations of the roundtrip time (RTT) between two nodes. We are designing and implementing a novel approach to eliminate inconsistent delays by reducing the control message exchanges in the network.
