Optimized Model for Energy Aware Location Aided Routing Protocol in MANET

摘要

Energy optimization for MANETs is essential to prolong the life time of the network. Location Aided Routing (LAR) is one of the reactive routing protocols where the nodes use their location information to assist in routing. LAR is very efficient in maintaining a good packet delivery ratio and other network measures. However, one of the common problems in LAR is that its energy unaware or it does not utilize the energy information in the routing. In this article, a developed Energy Aware LAR (EA-LAR) is proposed and simulated. It uses energy in routing based on a criterion function designed based on five important factors in the network. EA-LAR uses a PSO with mutation to optimize the criterion function. The Performance metrics that have used are packet deliver ratio, end to end delay, and overhead and energy consumption. The results have shown that EA-LAR outperformed other benchmark of energy improved LAR protocol from perspective of most evaluation measures. Most importantly, the energy consumption for one packet has been reduced with a percentage of 93% when the number of nodes was 100 nodes with a PDR improvement of 67%. This developed model can be generalized to other protocols to reduce energy consumption.
