Energy Aware Performance Comparison of Routing Protocols for Mobile Ad Hoc Networks

Abstract

Mobile nodes in an ad hoc wireless network are battery operated. Thus, it is essential to find energy conserving mechanisms and protocols that optimize the use of battery power in order to increase the lifetime of the network. When finding routes, energy aware routing increases the network lifetime. In this paper, I have considered three routing protocols DSDV, DSR & AODV for mobile ad hoc networks and evaluated the energy performance metrics in all the four modes- transmitting, receiving, idle and sleep along with other metrics such as residual energy, throughput, packet delivery fraction and end-to-end delay. I have observed that idle energy consumption is responsible for a large portion of the overall energy consumption in the wireless interfaces of the mobile
nodes. Finally, by the observation I have concluded that DSR offers the best combination of energy consumption, residual energy of nodes and delay while AODV gives better packet delivery fraction and DSDV gives more throughput.
