In this book, a framework for network integrated sensing and energy-aware protocols for resource-constrained applications in WBAN is developed. The key contribution is to develop a novel network-integrated sensing modality, which is inferred from the measured RSSI of the RF signal between each pair of WBAN sensors. The concept of RSSI-based proximity is experimentally developed and then integrated within a HMM-based stochastic processing framework for accurately identifying postures in a subject-independent manner. Then, the issue of energy-aware communication is addressed by developing a...
