Unity Multiplayer Android Game

I want to develop a multiplayer game with Unity. Mostly on Android platform. I know Unity and C #. I know a bit of Unity Networking (thanks to Unity Docmentation). What I want to do is how to develop multiplayer game with Unity for Android Platform. will be as follows: players will communicate over the network via Wifi Direct. One of the players will be the host and the server will be set up and the other players will be connected to the game as a client (just like playing Mini Militia etc.) How do I connect the network for this? I have very good ideas. I can even improve them singly, but it is very important for me to be a multiplayer.
