AODV Energy Routing Mechanism for Multi-Channel Multi-Interface Ad Hoc Networks (EMCMI-AODV) Using a Dynamic Programming Algorithm

Abstract

Energy consumption is a significant issue and offers a rich scope for research in ad hoc networks. However, many energy efficiency routing protocols are configured to use only a single Interface single Channel (SISC). As a result, these networks rarely can fully exploit all bandwidth available in the radio spectrum provisioned by the standards. This paper proposes two extensions to the shortest-path routing algorithm that finds routes to balance load based on residual energy of nodes and hops of route, one uses Floyd Warshall and the other uses Bellman-Ford algorithm. The protocols work with nodes equipped with a multiple network interface to overcome the problems of SISC where each node is equipped with a single antenna to ensure connectivity with all other nodes. The proposed protocols primarily exploit the idea of interaction among MAC and Network layers by using a novel cross-layer routing solution. The performance of the proposed protocols were evaluated using different scenarios and performance metrics, and achieved good results compared with similar works in the field.
