Enhancement of route maintenance in AODV over hybrid wireless mesh network

Abstract

Wireless mesh network has been considering as promising technology for next generation that provides a better services and guarantee to different internet applications. AODV routing protocol is being considered as routing protocol in hybrid wireless mesh network. Route breaks in mobile mesh client is one of the research issues in hybrid wireless mesh network, especially if the traffic comes from internet to mobile mesh clients. To ensure the robustness of the network a link breaks in routing protocol should be able to repair as fast as possible. In this paper, we have proposed a novel mechanism for the enhancement of route maintenance features of AODV in hybrid wireless mesh networks. The proposal mechanism uses the capability of mesh router backbone in terms of minimal mobility and no constraint in power consumption. Where border mesh routers that involves in route path between the internet gateway and mobile mesh clients can finds a new route when the route breaks if a local repair is fail between mobile mesh clients. Simulation results show that the proposed approach outperforms the standard AODV under routing overhead, end to end delay, throughput, number of packet delivery ratio in hybrid Wireless mesh networks.
