摘要: 首先从理论上对比分析了IEEE 802.11 DCF和IEEE 802.11e EDCA这两种MAC接入机制;然后运用NS2网络模拟软件,仿真网络中视频、FTP和背景流在不同MAC协议网络中的性能表现,证实了IEEE 802.11e EDCA能提供QoS支持,提升无线网络传输性能。

关键词: 无线网络, NS2, 分布式协调功能, 增强分布式通道存取

Abstract: The paper discusses the difference between 802.11 DCF and 802.11e EDCA which is analyzed theoretically firstly, then the NS2 network simulation software is used to simulate the performance in different network with video, FTP and exponential traffic stream to prove that the EDCA can support QoS and improve transmission efficiency of the wireless network.

Key words: wireless network, NS2, DCF, EDCA
