摘要：

Wireless body area network can provide e-health medical, athletic and entertainment services which has used in business applications widely. However, there exists serious shadowing fading of wireless transmission with correlative features brought by human movements which has reduced service quality and user experiences obviously. In order to research the correlative characters of wireless links in WBAN under moving conditions, a new shadowing fading modeling method named GMBO (geometrical method of body occlusion) for human body area is proposed. GMBO has two orthogonal planes one of which is for arm waving and the other of which is for torso in the coordinate system. Then the occlusion distant of wireless links in human body can be calculated in GMBO way based on the loss field theory. Both the occlusion factor of shadowing fading and correlative coefficient among wireless links can be calculated and quantitatively analyzed. This work make crucial sense for the assessment of channel capacity, outage probability and relay selection of cooperative communication in WBAN.
