Policy-based approach to emergency bio-data management for mobile healthcare.

In m-healthcare service, accurate detection and notification of emergency situation are critical to chronic patients' life. Since they are usually performed by a limited number of medical staff, it is difficult to simultaneously support many patients in real-time. This article presents an architecture to support the emergency bio-data management for m-healthcare service using personalized emergency policy. The salient feature of the proposed architecture is that the decision on emergency is made using personalized emergency policy. Specifically, the structure of the detailed system components has also been designed. The emergency condition of the individual bio-data collected from wireless body area network is detected automatically using personalized emergency policy. The message flow diagram based on the personalized emergency policy is described. This enables quick emergency rescue service provided to the patient both accurately and immediately. The prototype of proposed system has been built to demonstrate the design concept.
