IEEE 802.11 is the de facto standard for wireless communications. According to the 802.1 1 medium access control protocol, multicast frames are transmitted over ad hoc networks without virtual channel reservation. Hence, multicast communications in ad hoc networks suffer from the hidden
This thesis analyzes and compares four different mechanisms for providing QoS in IEEE 802.11 wireless LANs. We have evaluated the Point Coordinator Function (which is the IEEE 802.11 mode for service differentiation), Distributed Fair Scheduling, Blackburst, and a scheme proposed by Deng
