Implementing Mobile Tracking System on Disaster Notification

With advances in location based services,tracking the changing position of devices is becominga new challenge. Mobile devices are the mosteffective and convenient communication tools whichare not restricted by time and place. In this paper,the main service task is the timely delivery of possiblydisaster information to mobile devices which are inthe imminent disaster area.The system finds whether a mobile is within adefined disaster area using its GPS coordinates. Thesystem architecture is built for sending notification tomobile devices in disaster service area. This systemalso proposes an algorithm for client side whichcombines the time and distance-based locationupdateapproaches. This proposed algorithm will aidto get last current location and reduce server updatecost
