title: Android wifi connection
body: <p>Hie members! ----am Boniface M  - -  a beginner in android[University student]..</p>
  
  <p>My question is am planning to develop an android app/middleware that will act as a grid service .i.e an app for grid computing.. the application needs to be installed in 1....n devices. in the connection, one device must act as a server for all others. communication between the devices is via the wifi under the permission of the server device.which is determined by a certain algorithm[no problem here].</p>
  
  <p>The problem is should i use a database that will keep track of all the services a device is running which are accessible to other devices or is there any way that i can directly keep all this information and then retrieve them as i request them from another app installed in  another device.
  and also how i can share files via wifi like blutooth </p>
  
  <p>Thanks....</p>
