%X IEEE 802.11s is the standard defined for WLAN mesh networks and Hybrid Wireless Mesh routing Protocol (HWMP) is a default routing protocol for 802.11s based Wireless Mesh Networks (WMNs). HWMP uses Air Time Link metric to find out the best path. Air time Link metric outperforms hop count in mono channel mono radio environment. HWMP is affected by path instability and broadcast storm problem. Another main idea behind this routing algorithm is triggered by the routing procedure in partial infrastructure networks. All the existing routing protocols of MANETs can also be applicable for WMNs. But all the MANETs routing algorithms are designed for mobile nodes. But HWMP fails to utilize the partial infrastructure feature of the WMNs. But the proposed algorithm differentiates the stable nodes and mobile clients to make the routing more stable and efficient. The proposed node stability based client routing protocol improves the performance of IEEE 802.11s based WMN. This Protocol identifies new routes by considering stable nodes, Air time link metric and hop count. The simulation results show the protocol achieves improved throughput, packet delivery rate. It has less delay and packet loss compared to HWMP.
