A Tight Coupling Cooperation Scheme with QoS Provisioning in WiFi/WiMAX Networks
Keywords:
tight cooperation, WiMAX for WiFi, heterogeneous mesh networksAbstract
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 enables
WiMAX ful ll the procedure of bandwidth request-con rm-grant for WiFi was described
with 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. Numerical
results 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 networks
increase sharply without obvious decrease of WiMAX performance.
