Optimized Energy-Delay Routing in Ad Hoc Wireless Networks

Abstract

A novel optimized energy-delay routing (OEDR) protocol, which generates routes based on end-to-end delay, energy efficiency and state of the radio channel is introduced. Since energy spent over the radio channel indicates the quality of the communication link, the energy and delay product is considered as the link cost between any two given nodes. the OEDR protocol uses the concept of multipoint relays (MPRs) to minimize overhead while keeping the network energy efficient by selecting the MPR nodes using available energy levels. the link costs and the available energy at each MPR node are used to compute the optimal routes using a minimum cost spanning tree algorithm. Analytical results are presented to demonstrate the optimal performance of the proposed OEDR protocol. Network simulator (NS-2) demonstrate that the OEDR protocol results in a minimum delay, better throughput, and smaller energy and delay product over OLSR and AODV protocols resulting in a longer life time of the network.
