Power saving policies for multipurpose WBAN

Abstract

Wireless Body Area Networks (WBAN) present a variety of Power Management challenges ranging from radio protocols, to node components. In this work we focus on optimal exploitation of low power operating points in micro-controller-based sensor nodes under sensor sampling frequency constraints. We introduce general techniques to link the selection of optimal operating points, and operating point transitions, to application-specific requirements. We then demonstrate the application of the general techniques on a real-life use case. Experimental results show that the general techniques are applicable in practice, even though significant case-specific tuning is required.
