摘要 IEEE802.11作为无线局域网的MAC层规范而被广泛研究。介绍了IEEE802.11MAC协议中最基本的功能-DCF(分布式协调功能)的访问机制。在DCF研究的基础上对MAC层的性能进行了研究和分析,并针对802.11DCF的退避机制问题提出改进方案。 IEEE802. 11 was widely studied for it is the criterion of wireless networks.This paper introduces the basic function of MAC protocol 802.11-DCF(Distributed Coordinate Function) . On the foundation of DCF,it studies and analyses performance of the MAC layer.And,the paper brings forward an improved schedule of the Backoff mechanism.
