high performance modified dsr routing protocol for wlan mesh networks
This work presents a cross-layer modification to the DSR protocol which discovers high throug hput paths on multi-hop wir eless mesh networks. The modified DSR in corporates a metric based upon the bandwidth a vailability at a node into the routing discovery mechanism. We introduce the Access Efficiency Factor ( AEF ) as an a Iternative metric to the hop-count for the routing selection mechanism. In this modification, the selected path is identified by finding a path with the highest minimum AEF value. The OPNET modeler has been employed to investigate the performance of the modified DSR protocol on randomly generated network topologies of different node densities. Our results suggest that employing the AEF as a routing discovery metric can significantly increase the average global throughput of wireless mesh networks.
