Dagtas et al. [13] present a framework for remote health monitoring systems in which a mobile devices
collect vital signs from a Body Sensor Network (BSN) via ZigBee-based communication links. Mobile
devices then send the collected data to a central fixed server for further data analysis and storage. In their
architecture, mobile devices may partially process the data in order to detect immediate and life-threatening
situations, before sending it to the central server for further processing. All communications are directed to
the central server where the patient data is physically stored.
