Setting up communication between multiple iOS devices using NSNetServices class

Question

I am able to set up communication between multiple devices using NSNetServices class but only when those all devices are on same wifi network. Is it possible to make all the devices communicate regardless of the network availability, means it shouldn't matter if they are connected to same network or not connected to any network at all, just their wifi and bluetooth is on. And I don't wanna do it using MultipeerConnectivity framework.
