EEPR-OLSR: an Energy Efficient and Path Reliability protocol for proactive MANET routing

Abstract


Routing in Mobile Ad-hoc Networks has received a lot of attention due to the challenges posed by the self-organizing nature of the network, the dynamic topology, and the unreliable wireless medium. One of the most critical issues for MANETs is how to increase network lifetime, since nodes are typically battery powered. In this paper we consider the proactive MANET protocol OLSR to improve the network lifetime, we propose a novel multiple metric routing scheme for MANET, based on energy efficient and path reliability metrics, integrating it to standard OLSR, named Energy Efficient and Path Reliability OLSR (EEPR-OLSR), in which we investigate cross layer parameters that effect the network lifetime and a prediction-based link availability estimation is introduced. Simulation results, by NS3 simulator, show that the proposed EEPR-OLSR provides significant performance gains in both the network lifetime and packet delivery ration (PDR), compared to the standard OLSR.
