Ad-Hoc underwater acoustic networks have become very important in the field of defense industry, rescue operations and etc. But this technique faces some big challenges such as high end to end delay, bandwidth limitation and battery consumptions. The performance of the backoff contention window is the main factor for CSMA-CA that determines the efficiency in sharing and utilizing the limited bandwidth and power consumption in Ad-Hoc underwater acoustic networks. In this paper , practicable distributed backoff contention algorithm, which is named Fixed Backoff Contention Window (FBCW) for CSMA-CA in Ad-Hoc underwater acoustic networks. The FBCW for CSMA-CA is presented in Ad-Hoc underwater acoustic networks. Simulation results show that the proposed technique gives remarkable improvement in terms of average end to end delay, throughput and power consumption.
