Abstract
Reduction in control packets and minimization of setting-up time of the route are two challenging issues in wireless mesh networks. Solutions to these two issues are expected to save channel bandwidth and decrease the time delay, which in turn will improve the quality of services. In this paper, a mechanism, based on exploitation of local connectivity and overhearing concept, has been proposed for route discovery and route repair in the well known AODV (i.e., Ad Hoc On-demand Distance Vector) routing protocol. In this proposed work, any neighboring mesh node of the destination mesh node can provide a route to the source mesh node, even if the neighboring node does not have route entry about that destination in routing table. The promiscuous mode (overhearing concept) has been applied to reduce the number of duplicate control packets sent by neighbors of same destination nodes. Simulation results demonstrate how the proposed work outperforms the AODV under routing overhead, end to end delay, throughput, and packet delivery ratio in wireless mesh networks.
