You can use a Peer to Peer architecture to achieve this. Basically every phone is a client and a server the same time. See here for a basic implementation.

If the internet is not a prerequisite, you can follow Minav Patel's suggestion and use the Android Bluetooth implementation.

Another solution would be the WiFi-Direct feature (if the phone support it). See here for an example.
