无线局域网MAC协议分析和仿真研究

Analysis and Simulation Research on MAC Protocol of WLAN

随着笔记本电脑、掌上电脑、智能手机等移动终端的普及,无线局域网(WLAN)以其接入灵活、架构和扩展方便等优点得到了迅速发展,WLAN的网络性能(吞吐量、时延等)取决于MAC子层的接入协议。该文从原理上对WLANMAC的实现方式和差异进行了分析,并利用广泛使用的网络仿真软件OPNETITGuru针对差异进行了仿真分析,有助于深入理解MAC接入控制原理和不断演进的相关标准。

With the popularization of notebook PC,palmtop PC,intelligent phone and other mobile terminals,WLAN industry grows rapidly as a result of the advantages of flexible access,convenient construction and expansion,the performance of WLAN network（such as throughput,delay etc.） rests with access protocol of MAC sub layer.It provides theoretical analysis of the realization and difference of MAC sub layer of WLAN in the paper,with simulation and analysis using OPNET IT Guru,which is a extensive used network simulation software,it helps understanding in-depth of the access control theory of MAC sub layer and developmental standards.
