Abstract :
The standardization of IEEE802.11n which aims to achieve 100 Mbps at MAC-SAP (medium access control - service access point) is under work in IEEE802.11, wireless LAN standardization committee. The frame aggregation scheme in which MAC (medium access control) frames are aggregated into one PHY (physical) frame is proposed for IEEE802.11n, because it decreases MAC overhead. In this paper, we propose the compressed block ack mechanism as a selective repeat mechanism to be adapted to the frame aggregation scheme. We present simulation results to compare performance of the compressed block ack mechanism and the legacy block ack of IEEE802.11e and show that the proposed method improves the total throughput by 10% than the conventional method
