Performance Evaluation of 802.11e EDCF in Infrastructure Mode with Real Audio/Video Traffic

Multimedia wireless network QoS support has become one of the most important researches in recent years. IEEE wireless 802.11e is the most hopeful among these methods. However, 802.11e experiment performance metrics are essentially network-level measures. They represent the network state, not the perceptual quality of the end user. This paper presents an application-level study on the wireless 802.11 DCF and 802.11e EDCA scheme using an NS-2 simulator
