The personal server is responsible for interfacing and communicate with the medical server via the Internet, interfacing the WBAN sensors and fusing sensor data, and providing an intuitive graphical and/or audio interface to the end user. The personal server application can run on a variety of platforms with a variety of wide area network (WAN) access possibilities for Internet access. Platform selection is system specific and should be selected to minimize obtrusiveness for a given user [46]. The personal server needs ZigBee or Bluetooth capability for communicating within the WBAN; depending on the platform, this may be incorporated in the electronic device or setted as a separate plug in network coordinator (NC). The NC is …show more content…
In the case of a static residential gateway or home personal computer implementation, the personal server may be connected directly to a broadband Internet connection. The patient authentication information is carried by the personal server and is configured with IP address or domain name of the medical server so that it can access services over the World Wide Web. The PS schedules upload of health monitoring session files and data at periodic intervals or defers transmission in the event an Internet connection is unavailable [46]. In such cases, the personal server may be unable to propagate indicators of serious changes in health status. Because processing is performed on the personal server and on sensor nodes, the system should be capable of recognizing abnormalities and alerting the user to potential threatening physiological conditions.
The individual server does the following responsibilities [47]:
• Initialization, configuration, and synchronization of WBAN nodes
• Monitor and controlling Control and monitor actions of WBAN
