The underlying design in underwater acoustic wireless sensor network

Underwater acoustic wireless sensor network (UAWSN) is the result of global popularity of networks which combines underwater acoustic communication, networks, modern signal processing, sensor techniques and so on. Because of the particular characters of UAWSN such as big transportation delay, limited node power supply, many of the mature WSN techniques can´t be implanted to UAWSN directly. UW-CSMA/CA MAC protocol and UW-AODV Routing protocol are proposed in this paper to underlie the Data Link Layer and Network Layer of the network protocol stack of UAWSN. Simulations and experiments in Qiandao Lake show UW-CSMA/CA and UW-AODV are great and efficient solutions to the MAC and Routing protocol problems in UAWSN.
