摘要： 通过仿真实验，对分布式协调功能、快速冲突分解和新型自适应DCF 3种IEE802. 11无线局域网媒体访问控制机制的性能进行了分析和比较。仿真结果表明，与分布式协调功能相比，快速冲突分解机制大幅提高了网络的吞吐量，但网络的时延抖动和公平性却更加恶化;新型自适应DCF机制对网络的时延抖动和公平性改善较为明显，对网络吞吐量也有所提高。

关键词: 媒体访问控制，分布式协调功能，快速冲突分解，新型自适应DCF

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
