SUMMARY
A tight coupling cooperation scheme for WiFi/WiMAX networks with QoS provisioninghas been proposed in this paper. A new WFW (WiMAX for WiFi) module which enablesWiMAX ful ll the procedure of bandwidth request-con rm-grant for WiFi was describedwith a modi ed MAC layer of which MSH-DSCH (Mesh Distributed control message) re-newed, and thus overhead of interacting of WiFi control message was eliminated. The sched-ule is then evaluated through simulations in two typical transmission scenarios. Numericalresults show that more e ective WiFi/WiMAX heterogonous networks which o er QoS guar-antees are obtained with the utilization of the scheme. The eciency of WiFi Mesh networksincrease sharply without obvious decrease of WiMAX performance.
