Abstract: Analyzed and compared on the performance of three media access control mechanism for IEEE802. 11 wireless LAN,Distributed Coordination Function(DCF),Fast Collision Resolution (FCR) and New Self-Adaptive DCF (NSAD) by simulation. Simulation results indicate, compared with DCF, FCR greatly enhances the throughput, but de-teriorates the fitter and fairness of WLAN. NSAD improves the fitter and fairness notably of WLAN, and enhances a few on the network throughput.

Key words: Media access control,Distributed coordination function,Fast collision resolution,New self-adaptive DCF
