Simply in your broadcast receiver,

 if (WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION.equals(action)) { 
        WifiP2pDevice myDevice =(WifiP2pDevice)intent.getParcelableExtra(WifiP2pManager.EXTRA_WIFI_P2P_DEVICE);
        Log.d("Wifi Direct: My Device",myDevice.devicename); 
    }

After you turn on wifi on your device, it is send a WIFI_P2P_THIS_DEVICE_CHANGED_ACTION broadcast. You can catch this with a broadcast receiver and you can get a WifiP2pDevice object, that is your device.

 @Override
 public void onReceive(Context context, Intent intent) {
     WifiP2pDevice device = intent.getParcelableExtra(WifiP2pManager.EXTRA_WIFI_P2P_DEVICE);
     String thisDeviceName = device.deviceName;
 }
