Optimized Ad-hoc on Demand Distance Vector Routing Protocol

Abstract

--Wireless ad-hoc networks are characterized by the lack of infrastructure, use of wireless links with limited bandwidth and frequent topological changes. Enhancing route request broadcasting protocols constitutes a substantial part of recent research in Mobile Adhoc Network (MANET) routing. Ad-hoc On Demand Distance Vector Routing (AODV), is a novel algorithm for the operation of such Ad-hoc networks. Previous studies have shown limitations of Ad-hoc On Demand Vector (AODV) protocols in certain network scenario. We suggest a novel approach to constrain route request broadcast which by means of route optimization using cache mechanism. The performance of AODV has been modified by using route optimizing technique and thus called Route Optimised AODV (RO-AODV). This protocol optimizes AODV to perform effectively in terms of routing overhead, power consumption and delay during high load. Network Simulator2 (Ns2) can been used as the platform for the simulation environment to show how this optimized source route affects the performance of AODV routing protocol.
