摘要
Energy efficient routing 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 with two different classes of nodes, externally powered nodes and battery powered nodes. We embed both the energy and the device awareness into the routing protocol so that externally-powered nodes would, forward more traffic and perform more routing functions. The simulation results show that DEAR protocol achieves better system lifetime when compared to the conventional energy efficient routing protocols(1).
