Abstract

IEEE 802.11n WLAN was mainly developed to support a high data transmission rate toward 600Mbps based on the aggregation scheme that accumulates several sub-frames to transmit them into a larger frame. This concept reduces overheads and increases efficiency and throughput. Nevertheless, it cannot provide QoS satisfaction for delay sensitive application since it badly affects the delay. To outperform this inefficiency, we have proposed an admission control mechanism named Adaptation of Frame Aggregation AFA-CAC. In this paper, we further investigate the performance of our proposed QoS mechanism on supporting real time applications particularly on audio and video services.
