How to deploy a connection between two android devices using php host/server

I'm trying to send continuous data (like location) from android device A to android device B .

Right now android device A sends data to server and server saves data inside database and then device B reads data from server continuously.

1- Is there any way to connect this devices directly or in a way that there is less load on server?

2 Or a way to tell device B to wait until there is new data on server?

3 if I should use push notification for second question can I make a push notification server of my own and not use google cloud messaging?

4 how does messaging apps like Whatsapp and telegram handle sending data from one phone to another?

Well there are two possibilities that you could go with, the first would be to simply setup a long-polling or websocket connection from Device B to the server, instead of reading the direct data continuously with a new connection each time, you maintain a connection to the server and when new data comes in, the server sends it to you. For more information about this - checkout out this stack Q&A: What are Long-Polling, Websockets, Server-Sent Events (SSE) and Comet?

The other possibility would be to use push notifications via any number of push services. Personally I like to use the If This Then That (IFTTT) https://ifttt.com maker channel. This is good if it is a personal project, but if you're developing something for an app that you will distribute or as a commercial product you might want to look at some of the paid options. I've also heard that https://pushbots.com/ provides a good service but I haven't used it myself to say so definitely.

If you want to run your own push server check out http://airnotifier.github.io/ for a solution but I think, when it all comes down to it, everything uses the Google Cloud Messaging service, all the push traffic routes through that to get to your Android device as far as I know.
