Providing context-aware healthcare services using circular geofencing technique

Providing timely and appropriate medical help during a disaster or during an emergency situation is a key challenge in healthcare scenario. In this paper, we present Predictive Context aware Service (PCAS), which helps people in remote areas during disaster to search for a nearest doctor. This system not only finds the nearest doctor during that particular period of time but also finds the particular specialist which is required for the victim at the earliest possible time. We use circular geofence to predict the movement of the doctors and calculate the nearest location of the doctor from the patient. This paper focuses on a framework which provides context aware services by developing a mobile application to give enable the patient to register their details with symptoms, for searching for the nearest doctor with required specialization and to get medical service as early as possible time. The technique of this application can be used to search and inform the nearest rescue team in the disaster time, so that immediate action can be taken by the rescue team.
