Multipath energy efficient routing in mobile ad hoc network

Abstract

In ad hoc networks, energy conservation is a very important design issue. Several energy-efficient routing protocols are proposed to maximize the network lifetime which is defined as the time until the first node in the network runs out of energy. In this paper, we propose a Multipath Energy Efficient Routing (MEER) mechanism. We consider a network that is shared by a set of sources, each one communicates with its corresponding destination using multiple paths. MEER operates at each source node in a distributed manner and adaptively adjusts the traffic allocation among multiple paths with the objective of maximizing the network lifetime. We evaluate the performance of MEER by comparing it with some present energy efficient routing protocols via simulation. Satisfyingly, our proposal achieves the goal of more residual energy and better balanced energy residual, as a result the network lifetime is elongated. © Springer-Verlag Berlin Heidelberg 2005.
