Abstract

The emerging field of BSN, which centers on the human body, is attributed to the huge success of sensor utilization in assistive applications. With a sensing environment much different with that of a conventional WSN, a BSN has to be designed in a way which is focused on the power-constrained nature of body sensors. Thus, it is important that the network is well-coordinated in terms of measuring and transmitting data so as to minimize power consumption and prolong network lifetime. In this paper, we propose a power saving scheme which ranks sensors based on the priority level of the body parameters they measure and is used by the coordinator as a basis for deciding the parameters required for monitoring or diagnosis. The experimental results show that a BSN based on the proposed approach has much lower power consumption compared to conventional sleep/wakeup techniques.
