Geofencing for disaster information system

Due to the lack of effective and coordinated disaster management system which consists of the stages like disaster mitigation, preparedness, response, and recovery has led to both the increase in the loss of both life and property. The paper proposes an effective disaster information system which uses the geofencing technique so as to detect the movement of users. This technique creates a geofence around the user and thus monitors the user’s entry and exit from the fence. This model uses a K-Nearest Neighbour (KNN) algorithm along with real-time data collected from smartphones. For crowd disaster mitigation and real-time alert to avoid an occurrence of a stampede, this android application is an easily deployable context-awareness mobile Android Application Package. The application provides high accuracy when the user is in the fence.
