Energy efficient sensing in wireless sensor networks in body area networks

This article investigates wireless sensor network energy efficiency through sensor power demands and optimization of sensor power efficiency with cognitive radio and smart routing for use in green communications. Increase of energy efficiency of a local wireless sensor network for a predefined residential area using a smart routing system simulator (EnVO) is shown for both lossy and lossless data transmission for continuous communication. Different network topologies are discussed along with the best solution for minimum energy loss.
