IEEE P802.11 Wireless LANs

In this document we propose a scheme of packet Aggregation with Fragment-Retransmission (AFR) for the IEEE 802.11n. Simulation results show that the AFR scheme allows to meet the requirements of the IEEE 802.11n PAR [1], i.e. 100Mbps data throughput at MAC layer. Comparisons with 802.11 [2] and 802.11e [3] MAC layer protocols show that the AFR scheme outperforms both 802.11 DCF and 802.11e burst-ACK. 1
