title: Find all devices connected in a wifi network
body: <p>I am trying to make an app here, which will detect all the devices connected in that WiFi network. I have done enough google and come up with an <a href="https://github.com/rorist/android-network-discovery">App</a> which can detect IP Addresses of the devices connected in the WiFi network of the app.</p>
  
  <p>Now I want few more things.</p>
  
  <ol>
  <li>Can I find device name i.e. phone name or model or system name any
  information by which we can detect the particular device?</li>
  <li>Can we find the device distance like how far is that device from the
  phone in which we are using our app?</li>
  <li>This one is the <strong>main task</strong>- I want to share data over device
  connected to same WiFi. So is that possible?</li>
  </ol>
  
  <p>Any kind of help is appreciated</p>
