Abstract :
Energy consumption is not well balanced for all sensor nodes in most of the energy efficient routing protocols for wireless sensor networks (WSNs). In this paper, we optimize each individual distance so that all sensor nodes consume their energy at similar rate. After the theoretically analysis of hotspot based on certain energy and traffic models, we propose our Distance-based Energy Aware Routing (DEAR) algorithm for WSNs. Simulation results show that our DEAR algorithm has a better performance in energy consumption as well as network lifetime.
