There are two ways to do this: 1) have the phones running your app sign in to a central server with their location, and the server informs the phones of each other. Then they can contact each other however you like. One problem is that 50m is a small radius for the phone's ability to detect its location. 2) use zeroconf, also known as Bonjour, over WiFi. This is not built into Android, so you'd have to find a Java port, such as http://jmdns.sourceforge.net/ which is used in at least one other Android project: http://dacp.jsharkey.org/
