Energy Efficient Ad hoc on-demand Distance Vector Routing Protocol (EE-AODV) for Mobile Ad-hoc Network

Abstract

MANET[1] (Mobile Ad-hoc Network) is a temporary network in which every node is free to move independently and communicate with each other without relying on any centralized system. During communication it is obvious that nodes will keep on losing its energy and finally drain off when there is no sufficient energy left to complete any operation. Thus, it becomes essential to take into account the nodal energy of each individual node before forwarding a Route Request packet. Several protocols have been defined in order to discover route between a pair of nodes out of which the performance of AODV [2] Routing Protocol proves to be better among other protocols. However there are drawbacks in it too, like it blindly forwards RREQ packets and none of the existing protocols have considered Node Battery to make a forwarding decision. Without an appropriate forwarding decision associated with each node, a fair amount of node battery is consumed. In this paper we propose a new protocol named Energy Efficient Ad hoc On-demand Distance Vector Routing Protocol (EE-AODV) which is an improved version of traditional AODV considering node battery as one of the parameter for making a forwarding decision. Performance differential is analyzed based on Throughput, End-to-End Delay, Jitter, Packet Delivery Ratio (PDR) and Residual Energy. Simulation of various scenarios was performed in Qualnet Network Simulator that concludes that the performance of EEAODV in terms of Network Lifetime is better than AODV at the same time having better Throughput and lesser Average End-to-End delay.
