An Analytical Modeling of Polarized Time-Variant On-Body Propagation Channels with Dynamic Body Scattering
On-body propagation is one of the dominant propagation mechanisms in Wireless Body Area Networks (WBANs). It is characterized by near-field body-coupling and strong body-scattering effects. The temporal and spatial properties of on-body channels are jointly affected by the antenna polarization, the body posture, and the body motion. Analysis on the time variant properties of on-body channels relies on a good understanding of the dynamic body scattering, which is highly dependent on specific scenarios. In this paper, develop an analytical model to provide a canonical description of on-body channels in both time and space domains to investigate the on-body propagation over the trunk surface of a walking human.
