Abstract
In this paper, we propose an adaptive p-persistent based IEEE 802.11 medium access control (MAC) scheme in a heterogeneous WLAN. Quality of Service in a DCF based heterogeneous WLAN is a challenging task due to the lack of centralized scheduling capability. The proposed scheme can maximize the total channel throughput and provide the service differentiation among different traffic stations. This is achieved by updating the transmission probability for each station in a timely manner based on the real-time network measurements. The simulation results show that the scheme can quickly adapt the station transmission probabilities to the desirable values in order to achieve maximum throughput and QoS provisioning in a dynamic WLAN environment.
