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
