A New EAAODV Routing Protocol based on Mobile Agent

Abstract

This paper proposes a new routing scheme for mobile Ad hoc networks .. EAAODV (Energy-Aware AODV), which combines the on-demand routing capability of Ad hoc On-Demand Distance Vector routing protocol with a distributed topology discovery mechanism - mobile agents. Utilizing the interior characteristics of the mobile agent technology, EAAODV obtains the dynamic energy distribution in the network, thus reaching the balance condition. EAAODV eliminates the problem of low efficiency and link breaking in routing due to the energy exhaustion of some nodes, which exists in the traditional protocols. This paper analyzes the scheme by means of both mathematics and simulation technologies. Results show that EAAODV hybrid protocol proposed in this paper is able to achieve a longer surviving network duration and a larger throughput compared to the traditional AODV protocols.
