چکیده
In this paper, UW-MAC, a distributed Medium Access Control (MAC) protocol tailored for UnderWater Acoustic Sensor Networks (UW-ASNs), is proposed. It is a transmitter-based Code Division Multiple Access (CDMA) scheme that incorporates a novel closed-loop distributed algorithm to set the optimal transmit power and code length. UW-MAC aims at achieving three objectives, i.e., guarantee high network throughput, low channel access delay, and low energy consumption. Experiments show that UW-MAC outperforms existing MAC protocols tuned for the underwater environment under different architecture scenarios and simulation settings.
