Title: A Power efficient pulsed MAC protocol for body area networks
Author: Layerle, David
Abstract: The need for a reduction in healthcare cost has escalated over the past decade. Therefore, preventive medicine through remote health monitoring and Body Area Networks has gained more attention. This paper presents a novel Medium Access Control (MAC) protocol called Pulsed-MAC or simply PMAC to efficiently manage wireless communications in Body Area Networks. PMAC drastically extends the network life time by augmenting sensor nodes with charge pumping circuitry which harvest energy from a pulsed signal used to orchestrate communications. By measuring the average radio power consumption in a sensor node over a 24 hour simulation period, results show that PMAC outperforms conventional SMAC by up to three times and will easily allow for a Body Area Network to last beyond 200 days.
