Namespaces are expanded for you automatically. You can see some examples here:

In your particular case, you might need to know the target node's name and do something like this:
```
communicationNode.createClient("/" + nodeName + "/get_state");
```
But I'm not 100% sure without seeing what you're doing exactly.
