Abstract: Through performance analysis for MAC(Media Access Control) protocol in Wireless Local Area Network(WLAN), it can understand in depth the operational characteristic of MAC protocol and find out the essential reason of affecting the performance of MAC protocol, such as throughput, packet delay and packet loss. It elaborates detailedly the related work using the Markov chain analysis and gives a survey of the related work of performance analysis for the distributed coordination function and enhanced distributed channel access MAC protocol in WLAN. It gives analyses and outlooks for the further research.

Key words: wireless local area network, Distributed Coordination Function(DCF), Enhanced Distributed Channel Access(EDCA), Markov chain, performance analysis

摘要: 对媒体接入控制(Media Access Control,MAC)协议进行性能分析,可以深入理解MAC协议的操作特点,发现吞吐量、数据包时延与丢失等性能遭受影响的本质原因。对当前马尔可夫链性能分析法加以详细地分析与总结,分别阐述了无线局域网络中分布式协调功能和增强的分布式信道接入两种MAC协议的性能分析研究工作。对进一步的研究工作进行了分析与展望。
