Performance enhancement of AODV using piggyback and neighbor stability technique.

Abstract

Abstract— In a MANET, no such infrastructure exists and the network topology may dynamically change in an unpredictable manner since nodes are free to move. Then the probability of breaking of links may increase and the interruption will lead to higher route cost and longer delay due to frequent route repair. So mainly discovering the stability of links has become necessary and important. The goal of this paper is to understand the behavior of the basic AODV protocol & then to improve the performance of AODV using Piggyback mechanism & Neighbor stability technique. Also we have comparative study of Basic AODV & Enhanced AODV with some performance metrics using Operating System as Ubuntu 12.04 & network simulator NS2.35 .
