Comparison of Energy Efficient Routing Protocols in Mobile Adhoc Networks

Abstract

Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change positions frequently. To accommodate the changing topology special routing algorithms are needed. The main classes of routing protocols are Flat Routing, Hierarchical Routing and Geographic Position assisted Routing. For relatively small network flat routing protocols may be sufficient. However in large network either hierarchical or geographic routing protocols are best. There is not any single protocol that fits in all type of networks perfectly. The protocols have been chosen according to network characteristics, such as density, size, mobility of nodes and the application area. In this work an attempt has been made to compare the energy awareness of three prominent routing protocols for MANETs:-Destination Sequenced Distance Vector Routing Protocol (DSDV), Ad hoc On Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) protocols. The performance of these protocols has been analyzed on different parameters with varying simulation time. These simulations are carried out using the ns-2 network simulator.
