The sensor location on the body is an important attribute in Body Sensor Networks (BSNs), because it is highly possible that the signals may look totally different when a person performs the same activity but with sensors at different locations. At present, nodes positions on the body are manually predefined in BSNs. With the development of BSNs and sensing technology, more nodes will join in BSNs in order to detect more physiological signals. It results that it will be difficult or even impossible to operate manually nodes positions in BSNs.
