Abstract

Recent technological advancement- in wireless communication has invented Wireless Body Area Networks (WBANs), a cutting edge technology in healthcare applications. WBANs interconnect with intelligent and miniaturized biomedical sensor nodes placed on human body to un-attendant monitoring of physiological parameter of the patient. These sensors are equipped with limited resources in terms of computation, storage and battery power. The data communication in WBANs is a resource hungry process especially in terms of energy. One of the most significant challenges in this network is to design energy aware next-hop link selection framework. Towards this end, this paper presents a Green computing framework for WBANs focusing on Energy efficient Link aware approach (G-WEL). Firstly, a link efficiency oriented network model is presented considering beaconing information and network initialization process. Secondly, a path cost calculation model is derived focusing on energy aware link efficiency. A complete operational framework G-WEL is developed considering energy aware next hop link selection by utilizing the network and path cost model. The comparative performance evaluation attests the energy oriented benefit of the proposed framework as compared to the state-of-the-art techniques. It reveals a significant enhancement in body area networking in terms of various energy oriented metrics under medical environments.
