A Wireless Physiological Sensor Area Network

Generally, physiological data as the health indicators of an elderly can effectively reflect his/her health status which in turn shows whether he/she has fully satisfied with his/her everyday life or not. A healthcare sensor system for elderly is a sensing system that serves elderly people with a wireless physiological sensor area network (WPSAN for short) and physiological sensors (Bio-sensors) to monitor their healthy conditions. In this study, we develop a wireless physiological sensor architecture which integrates a Wireless Body Sensor Network (WBSN for short) and different sensors to sense physiological data for an elderly, and then transmits the data to a remote healthcare cloud through a smartphone. Due to sensing many elderly people simultaneously, the remote side collects the data with a special system, named Data Collection and Classification Subsystem (DCCS), to avoid losing any data sent by the smartphones. The DCCS then classifies the receiving data based on individual´s personal ID and types of sensors, and distributes the classified data to their corresponding databases created in the healthcare cloud, from which healthcare givers can access and monitor the physiological data of an elderly via a healthcare monitoring system, and then timely give suitable healthcare to the elderly when necessary.
