Adaptive MAC Protocol in Ad hoc Networks

A new medium access control (MAC) protocol based on fuzzy logic is proposed for Ad hoc networks. In MAC layer, the fuzzy logic is used to choose a proper add-in back-off window size for different priority flows. Thus, the low priority flows, interacted on the higher ones, can reduce their access probabilities. Simulation result shows that the new protocol can achieve better performance compared with 802.11e protocol in the terms of end-to-end delay and throughput of high priority flows.
