Energy Competent Routing Protocol Design in MANET with Real Time Application Provision

Abstract

With the increase of mobile activities in technological environment, it is a challenge to develop and maintain robust networking system with provision of high connectivity. In this context, Mobile Adhoc Network (MANET) is a feasible solution because it is dynamic in nature and the self-configured nodes of MANET can communicate intelligently in adverse and dynamic mobile situations. Though Adhoc on Demand Distance Vector (AODV) Routing protocol handles the networking issues efficiently, still power and delay efficiency has always been a challenging task in MANET due to the resource constrained nodes which are supplied with limited battery power during the operation in the network. Hence while performing various networking activities; gradually the battery power reduces resulting in delay in processing of packet and forwarding them to the next node during transmission. This causes overall end to end delay in the total transmission. Therefore many researches are still going on in the direction of designing robust and reliable protocols. In this paper the authors have developed a robust and energy efficient routing protocol for MANET with real time support. Their approach is different as it calculates the remaining residual battery power, bounded delay and packet processing rate of the intermediate node before selecting a node to forward the packet in the direction of destination. The cost function calculated using the above three factors along with the condition of congested node is also checked to correctly choose a load balanced path from source to destination. Simulation results show that the proposed protocol performs better than the conventional AODV protocol in terms of better network life time, throughput, delay and packet delivery ratio.
