Abstract :
This paper analyzes and compares four different mechanisms for providing QoS in IEEE 802.11 WLAN. And it evaluates the IEEE 802.11 mode for service differentiation (PCF), Distributed Fair Scheduling, Black burst, and a scheme proposed by Deng et al. using the ns-2 simulator. The evaluation covers medium utilization, access delay, and the ability to support a large number of high priority mobile stations.
