Tracking and Positioning of Non-GPS Phones Using Bluetooth

The Bluetooth Server is deployed at different Areas and it’s ID is transmitted to the Server. GPS Enabled will also roam around the City everywhere. If Non GPS Mobile User is available within the Limit of Bluetooth Accessibility, then User’s Location is easily tracked. If User is out of Bluetooth Coverage area, then GPS Enabled Users will communicate with Non GPS Users via Bluetooth and the location is communicated to the Server. User can download a File from the Server without GPS Connection through Bluetooth Communication from Rest of the Users. GSM and WiFi communication networks where fixed reference points are densely deployed positioning and tracking techniques in a sparse disruption tolerant network (DTN) have not been well addressed. I propose a decentralized cooperative method called Pulse Counting for DTN localization and a probabilistic tracking method called Protracting to confront this challenge.
