thank's for the answer.
but i still don't understand how i configure that it's WIFI connection: i just open a socket on the server and the client is trying to connect to the server by its host name, ip by wifi itself. So the server don't care how the connection is established?Right. It doesn't care. You have a client and a server on your local WiFi network. Or maybe the client is in the WiFi and the server is out on the internet. Regardless, you write exactly the same code, and neither the client nor the server knows that there's WiFi involved. Just like when you talk on the phone, you don't know or care if you're talking over fiber or underground cables or above-ground cables or satellite, or some combination, similarly, at all the layers above the Link layer the networking code doesn't know or care what's underneath. Your app just opens a socket connection to an IP address.
The one case where it gets tricky, but your app still doesn't know the difference, is of the client is on the internet and your server is on your LAN. It has nothing to do with whether the LAN is WiFi, however. It's because you will most likely not have a public IP address, so you'll have to do port forwarding from your router (assuming it actually does have a public IP address, which is common in my experience, but not guaranteed).
