Abstract

Due to the long preamble problem in underwater acoustic networks (UANs), traditional sender initiated handshaking MAC protocols are facing high overhead of control messages. To mitigate this problem, we propose a traffic estimation based receiver initiated MAC (FERI MAC) for UANs. In FERI MAC, a traffic prediction based adaptive data polling approach is used to help receiver request the data from neighbors at the right time. Via simulations, we evaluate the performance of FERI MAC, in terms of energy efficiency, channel utilization and one-hop delivery delay. FERI MAC shows a stable energy efficiency and channel utilization with arbitrary network traffic patterns. Our results also illustrate that, compared with existing receiver initiated MAC protocols, FERI MAC can achieve a higher energy efficiency while with some delay penalty. This confirms the strength of FERI MAC for delay tolerant underwater applications.
