Abstract
In ad hoc networks, where there is no infrastructure, batteries lifetime are scare resource. However, many routing protocols in ad hoc networks have been proposed to provide and maintain routes without taking into account energy consumption. Recently, power control in mobile ad-hoc networks has been the focus of extensive research. In this paper, we propose a new scheme to make energy aware routing in OLSR (Optimized Link State Routing Protocol). OLSR is one of the routing protocols under study by the IETF MANET Working Group. We develop a new heuristic that allow OLSR to find an optimal power path in which the maximum energy consumption on that path is smaller among the maximum energy consumption of all possible paths. We discuss via simulation the interplay between routing in new OLSR protocol and the medium access control (MAC). Also we study the over-hearing impact on the energy power-aware routing protocol. Simulation results show that our scheme improves classical OLSR routing while taking into account lifetime of the network.
