Simulation study of IEEE 802.11e EDCF
Dajiang He, Chong Shen · 2004
This paper presents a simulation study on IEEE 802.11e enhanced distributed coordination function (EDCF) mechanism, designed by the IEEE 802.11 group to enhance the original 802.11 MAC with QoS facility. Based on ns2 platform, simulation study was conducted using various network configurations and traffic patterns. The results basically prove the effectiveness of MAC service differentiation provided by EDCF compared to DCF and also point out the limitation of EDCF to support real time traffic in wireless LAN environment.
