In wireless mesh network, there is a need of efficient Cross-Layer Design Architecture for Routing and Channel Selection in Multi-Radio Multi-Channel Wireless Mesh Networks. For this we propose interference and congestion aware cross-layer architecture for wireless mesh networks. The proposed technique first we apply Cross-Layer QoS-Aware Routing Protocol, in which we use bandwidth estimation for physical routing and ICA metric for logical routing. We select the channel by using Channel Quality Variables at last we Optimize and adjust the cross-layer metrics using delay dissatisfaction ratio, Throughput dissatisfaction ratio and PER dissatisfaction ratio. Our proposed technique selects high quality paths and interference free channels also makes effective utilization of the available interfaces and prioritizes the packets in the event of congestion.
