I'd like to develop the app which run on a mobile phone. It acts like a server which is able to be accessed from the PC app which will request for the mobile info such as the GPS coordination. The mobile phone running this app will be response automatically with out human action.
The point is the mobile phone could be in the GSM/CDMA or Wifi network which its ip address is dynamically assigned.
Do you guys has any idea how to connect to the server on the public network with dynamically ip assignment like this?
P.S. The mobile phone can connect to the PC app, since I can set up a dns service stuff on the PC side. Just let you guys know.
