Abstract: This paper proposes a kind of MAC protocol to improve the QoS of Wireless LAN(WLAN), describes the scheme of the protocol, and gives the comparison of the average delay and normalized throughput when transmitting real-time voice data between this protocol and 802.11e Enhanced Distributed Coordination Function(EDCF) by simulation. The simulation result shows that this protocol performs much better than EDCF when transmitting real-time data irrespective of load magnitude. So this protocol utilizes the channel more effectively.

Key words: Wireless LAN(WLAN), QoS, MAC, Enhanced Distributed Coordination Function(EDCF)
