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 ad 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. r
DEAR (Device and Energy Aware Routing) protocol REF considers the heterogeneity of the nodes in terms of the power source.
