An efficient routing protocol for ad-hoc networks

Abstract

A mobile ad-hoc network is infrastructure less, self organizable, multi hop packet switched network. In ad-hoc network, node movements results in dynamic topology and frequent link failures. Studies shows that on demand protocols perform better compared to table driven protocols. Ad-hoc On Demand Routing (AODV) is one of the popular on demand routing protocol. In this paper, we have proposed an innovative method by considering the MAC layer feed back to reduce the route discovery latency and routing overhead of AODV protocol. Also proposed a new approach of preemptive route maintenance to miti gate the delays and overhead incurred during the original AODV. We implemented and simulated the proposed scheme in NS 2. Simulation results show that the pro posed scheme performs better than AODV. © 2011 Springer-Verlag.
