Evaluation Of Energy Efficiency Of MANET Routing Protocols

Abstract - Now days network is becoming an important part in varying area and demand of users with the rapid development of the wireless device has motivated the emergence of the mobile ad hoc network. MANET Mobile ad hoc Network. It is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. MANETs dont need of any centralized base station and can be set up anytime anywhere. In MANETs the nodes are mobile and battery operated. As the nodes have limited battery resources and multi hop routes are used over a changing network environment due to node mobility it requires energy efficient routing protocols to limit the power consumption prolong the battery life and to improve the robustness of the system. This research presents a comparison and evaluation study of Reactive routing protocols Ad Hoc On-Demand Distance Vector Routing AODV Proactive routing protocols routing information protocol RIP2 and Position-based routing protocol Location- Aided Routing LAR1. And the evaluation of their performance was based on energy consumption metric. The evaluation study performed using QualNet v5.1 simulator. This research showed that AODV has the best evaluation performance in energy usage in all most scenarios.
