A Study of Channel Characteristics in Wireless Body Sensor Network Systems
نویسندگان
چکیده
Unlike existing wireless sensor network (WSN) environments, wireless body sensor network (WBSN) environments can have dynamic channel characteristics depending on sensor placements, human movements, and surrounding environments. In this study, to analyze such WBSN channels, the stomach, back, forearm, wrist, thigh, and ankle were set as sensor placements and standing, walking, and running were set as human movements to conduct experiments. Channel environments were analyzed through the experiments and the variations of the characteristics of received signal strength indication (RSSI) values depending on individual sensor placements and human movements were compositely analyzed.
