Abstract :
An effective scheduler is proposed to improve the performance of IEEE 802.11e wireless local area networks (LANs), which adaptively adjusts the ratio of enhanced distributed channel access (EDCA) duration to controlled access phase (CAP) duration by tracking the amounts of variable bit rate (VBR) and constant bit rate (CBR) traffics in a real-time manner. Simulation results show that the proposed scheme significantly improves quality of service (QoS) in terms of throughput and delay metrics
