Should i use one or multiple to communicate?

edit

I am trying to send the information from multiple turtlebots to one workstation (2 at the moment). I have tried to communicate over the basic port and use different ports for each turtlebots. What do you recommend I do? I would like to have all the data available from the worstation which would lead to seeing each robot data on a single Rviz window. I will also need to be able to control multiple turtlebots from the workstation? Has anyone here done that already? Any advice?

Thanks for the help,

Cheers,
