DEAR: A Device and Energy Aware Routing protocol for heterogeneous ad hoc networks
Energy efficient routing in ad hoc networks has been the subject of intensive study in recent years. Most work has been focused on residual battery power related cost metrics for a homogeneous ad hoc network, where all the nodes are considered identical in terms of functioning and available resources. In this paper, we propose a Device and Energy Aware Routing protocol (DEAR) for a heterogeneous wireless Lid hoc network where there exist two different classes of nodes, battery-powered nodes and externally powered nodes. By embedding both the energy and the device-type awareness into the routing protocol, we force the externally powered nodes to forward more traffic and perform more routing functions than a battery-powered node. The simulation results show that DEAR protocol achieves better system lifetime when compared to the conventional energy efficient routing protocols. (C) 2003 Elsevier Science (USA).
