A new technique for multiple-path creation in AODV protocol based on composite criterion consisting of the factors of energy, traffic load and stability of nodes

Abstract

Not long ago mobile ad hoc networks (MANET) became one of the most recent and famous trends in the field of wireless communications. This is because, it permits the mobile appliances for communication with each other at any instant anyplace without the need of pre-defined infrastructure or centralized management. As the absence of centralized administration, the free movement of appliances and the limited resources of MANET, the designing of routing protocols have been becoming the main fundamental challenge that meet MANET till now. Furthermore, nodes with heavily traffic load may exhaust their energy in routing others packets resulting in unstable network and hence performance deterioration. In this essay we present a new version of one of the well prominent reactive routing protocols named Ad Hoc On Demand distance Vector (AODV). The suggested version aims to make the original AODV more efficient in terms of the energy consumption of nodes, traffic load distribution among nodes and routes stabilization. The suggested scheme is called, Energy efficient, Load balanced and Stabilized Multi routes-AODV (ELSM-AODV), where the paths selection is based on a composite criterion, named Node Efficiency Factor (NEF) which contain all factors that have direct impact on the performance level and life time of MANET (e.g. energy, speed, distance and traffic load of nodes). Performance assessment and comparison between suggested schema (ELSM-AODV) and standard AODV has been performed using network emulator NS2. Simulation results evidenced that performance of the suggested protocol outperform standard AODV from point of view: correct packets delivery ratio, end to end delay time, normalized routing load and nodes energy consumption.
