Right now there is no real P2P possible on Android using the
official SDK APIs.

In case of Wifi there is no support of Ad-Hoc. You could try to use a
multicast approach where you try first to discover which devices are
in the WLAN. Problem with multicast/broadcast on Wifi is that your
network performance gets impacted very fast when you add the number of
clients in the network. Also the type of traffic in the WLAN
influences the throughput.

If you think about using a central server then I would not all your
setup P2P anymore.

 Put a server between them, and have each of them talk to the server.

 NAT punchthrough and such isn't easy, and to be honest, with a game, you
 want some sort of central system to make sure everything is legit

  Hello all,

  I'm with a group of college students making a multiplayer game as a
  class project on the Android platform for the G1. Our primary goal is
  to allow multiple phones (or for the sake of initial testing, a phone
  and an emulator on a PC) to communicate with one another. Our game is
  turn based, and we've been looking into TCP/IP and VNC proxy servers
  to transfer data between the game clients on each phone, but none of
  them seem particularly simple to implement. We've been through many
  articles documenting how difficult peer-to-peer connections are on the
  Android platform.

  What would some viable network protocols to use for the sake of our
  project and how should we go about setting them up?

  Thanks,
  S
