In this paper, we provide higher channel access priority to frames belonging to real-time traffic with smaller contention windows as compared to frames belonging to besteffort traffic. Further, to reduce channel access delay in multihop environment, we give higher access priorities to relayed frames, within a QoS class, as compared to the generated frames within the same class. Besides introducing channel access priorities at MAC layer, proper queuing management scheme is implemented to improve the QoS support at flow level. Both analytical and simulation results show the improved QoS for real-time traffic.
