By calculating the time difference, distance from a router or a fixed point can be determined. The packets can be manually made in Eclipse or any other java operated software. For tracking the trains we need to use Wi-Fi trackers which will communicate with the nearest router and the router will pass the information to the central server. The central server will process the information and store them in a server. The information then will be shown on a webpage or android app.51 pagesenBRAC University thesis are protected by copyright.
