Executive Summary

Significant research efforts are being devoted to Body Area Networks (BAN) due to their potential for revolutionizing healthcare practices. Energy-efficiency and communication reliability are critically important for these networks. In an experimental study with three different mote platforms, the authors show that changes inhuman body shadowing as well as those in the relative distance and orientation of nodes caused by common human body movements can result in significant fluctuations in the received signal strength within a BAN. Furthermore, regular movements, such as walking, typically manifest in approximately periodic variations in signal strength. The authors present an algorithm that predicts the signal strength peaks and evaluate it on real-world data.
