An link adaptation scheme for improving throughput in the IEEE 802.11 wireless LAN

Throughput performance is very important to the QoS provisioning in wireless data networks. We propose a link adaptation algorithm for the throughput performance improvement of the IEEE 802.11 wireless LAN. In this algorithm, an optimal frame size predictor with considerations of collisions and frame errors is proposed. Simulations results show that the throughput performance of the wireless LAN can be enhanced greatly than that achieved by traditional fixed frame size scheme.
