无线网络的媒体接入控制的研究

Research on media access control of wireless network

WLAN作为一种无线接入网络,在许多场合下正扮演着越来越重要的角色。本文介绍了无线局域网标准和无线局域网QoS的相关情况,重点介绍了DCF机制,对DCF进行理论分析,通过编写C语言程序在OPNET里的仿真,得到了影响节点的吞吐量和延时的参数,最后对参数进行了分析。

WLAN as a wireless network access technology, is playing a more and more important role in many occasions, the wireless LAN standards and Wlan related QoS were introduced, focused on DCF mechanism, the author builts modeling of DCF using program c in Opnet software, and abteined the parameters impacting on bandwidth and delay of nodes, in the end, the Parameters was analyzed.
