Energy Consumption Routing for Mobile Ad Hoc Networks

The specific features of mobile ad hoc networks (MANETs) impose new requirements for routing protocols. The aim of this paper is to present an approach that enhances routing performance by integrating ad hoc related characteristics. We propose a loop-free adaptive path energy conserving scheme which attempts to minimize both routing and storage overhead in order to provide efficiently robustness to host mobility, adaptability to wireless channel fluctuations and optimization of network resources use in large-scale networks. The strength of our scheme, based on source routing approach, named Energy Conserving Routing (ECR), is to handle network state related constraints such as node’s energy consumption, link availability and path quality. The performance of the proposed scheme is evaluated via simulation and is compared to DSR protocol. Better results are obtained with ECR in terms of path lifetime, forwarding efficiency, delay, and total overhead.
