Abstract

Today’s IEEE 802.11 WLAN is an excellent solution for the broadband wireless networking. However, it lacks the capability to support real time services such as voice and video. IEEE 802.11e is an upcoming QoS enhanced standard supported by the IEEE working group. IEEE 802.11e protocol provides a level of service differentiation by statically associating different QoS parameters for pre-defined traffic classes. This paper describes the new QoS features of 802.11e protocol. The performance of 802.11e will be investigated and compared with legacy protocol through computer simulation. Additionally, the 802.11e WLAN capacity will be presented in different scenarios.
