A subject-specific radio propagation study in wireless body area networks

This paper presents a study of subject-specific radio channels in wireless body area networks (WBANs). The simulation tool is based on a parallel finite-difference time-domain method (FDTD) and is well suited to model radio propagations around complex, inhomogeneous objects including human bodies in WBAN. It is found from our study that radio channel characteristics in WBAN are subject specific when the received signal mainly contains the contribution of creeping waves around the human body.
