When you say all systems, I assume you mean all instances of your application? If so then the correct solution is to use Bonjour. Documentation on how to use it can be found here. Note that your app needs to be actively running on all the devices that you are trying to discover, since the iPhone does not support background apps.

If you are just talking about finding all other devices in the area then you need to resort to techniques like port scanning.
