Enhancement Route Maintenance for Routing Protocol in Wireless Mesh Network.

Route breakage between mesh clients is one of the research issues in hybrid wireless mesh network, especially if the traffic comes from internet to mesh clients. To ensure the robustness of the network, the routing protocol should be able to repair the route as fast as possible. In this paper, we propose a mechanism to enhance route repair in the well-known AODV routing protocol. The proposed mechanism uses mesh routers that part of the route for repairing the route break between gateway(i.e. source node) and mesh clients(i.e. destination node). The mesh routers have capabilities in terms of minimal mobility (i.e. most of the time are static) and have no constraint in power consumption. The Simulation results show that the proposed approach outperforms the AODV for routing overhead, end-to-end delay, throughput and number of packet delivery ratio.
