In wireless body sensor system, various multipath environments can be established because sensor nodes can be moved to many locations as it is deployed in parts of the human body. This study compared and analyzed changes of the received signal strength (RSS) in various experimental locations, such a ground site, corridor, and room, as an actual sensor device is attached to a human body. Experimental results showed that the room, which contained many multipaths, exhibited the best RSS. The ground site, which had the lowest number of multipaths, registered the worst RSS. On the basis of these findings, we conclude that the design of body sensor systems should consider the presence of multipaths in various experimental locations.
