Guidelines to handle connection loss

edit

Hi all, I'm interested in the ways you all solve connection loss in the ROS network.

Every wireless connection is unreliable and is lost from time to time (so far from my experience). So I'd guess somebody has already thought about what to do then.

The only thing I've found is http://answers.ros.org/question/19896... , where there is a statement that ROS has no support for reestablishing connections.

Can I do some defensive steps in my code, like checking the status of subscribers/publishers and reconnecting them if they seem to lose connection? What other steps may I do?

Thanks for sharing your ideas.
