  • You want do a multicast. See http://stackoverflow.com/questions/3623143/multicast-on-android-2-2 for implementation in Android. – Rodja Aug 31 '12 at 04:38

If you cannot use any IP Address, its better to use Push Notification using GCM.

When ever you need to broadcast something, just need to send a message to GCM Server, which will notify the clients which has suscribed for this type of message.
