The utilization of body skeleton model for modeling the dynamic BAN channels

This paper proposed the skeleton model to generate human body models for predicting dynamic BAN channels by considering the simplified body geometry in analytical study. The numerical human body model was exported into skeleton in bvh (bio-vision hierarchy) file format. The cylinder body model is constructed by shaping the necessary bones of skeleton by cylinder. The feasibility of model is assessed by FDTD simulation. The results show reasonable agreement between channels calculated from the complex and simplified body models. By using skeleton, the motion data can be transferred into a small size file without losing necessary information for channel prediction.
