摘要: This paper considers the performance problem of VoIP over 802.11e WLANs caused by unfairness between uplink and downlink as well inefficient EDCA. A novel medium access control scheme named BEDCA (Balanced EDCA) is presented, which provides service differentiation point (AP) mobile stations (STAs) to enhance capacity. In BEDCA, expression AP's contention window obtained a relative constant value independent participating STAs. The minimum STAs traffic-aware based on proposed algorithm. improvement verified through intensive simulations results show capacity 82.1% compared
