You can setup Wifi in two different modes -- infrastructure mode: in this mode you are using a Wifi Access Point (AP) as central router. You get your IP address from the AP when you have DHCP enabled.
-- ad-hoc mode: This is a mode in which you can enable peer to peer communication to other Wifi devices without having to setup an infrastructure. Because Android on SDK level has no Ad-Hoc support (at least I am not aware of that there are APIs available) you only can use what is available on native level. In case you are setting up your devices in infrastructure mode you can communicate with other Wifi devices over the central AP. You could use a broadcast IP address for your communication. Question is whether this would fulfill your requirements.
