Enhanced Synchronized Medium Access Control Protocol for Wireless Ad Hoc Networks

An enhanced synchronized medium access protocol, named ES-MAC, for wireless ad hoc networks is proposed in this paper. ES-MAC employs a binary-countdown scheme to resolve contentions between wireless stations. Multiple contention periods and hidden station elimination periods are adopted to increase the throughput and channel utilization of the system. Our simulation and analysis show that ES-MAC can achieve a promising performance in terms of throughput, fairness and channel utilization. With channel utilization as high as 96%, ES-MAC can also be employed as an alternative MAC protocol in wireless access network.
