Abstract
Current WLAN is still predominantly data centric, so it is not well equipped to meet the pressing voice capacity and quality of service (QoS) demands when transmitting VoIP traffic. One of the reasons is the large WLAN PHY/MAC overhead. This paper proposes and investigates a MAC queue aggregation scheme which aggregates multiple queuing MAC frames to reduce the overhead. The scheme will not incur any extra delay. Simulations in various scenarios show that the proposed scheme can improve the VoIP capacity by up to 65%.
