Best method for Kobuki communication?

edit

I am working on creating a communication platform so that three Kobuki robots can communicate with one another and relay information when moving/doing tasks together. Each Kobuki has a laptop controlling it that can use WiFi or Bluetooth. Are there any good pre-existing ROS packages for this sort of task and (subjectively) is Bluetooth or WiFi a better choice?

Each laptop is running ROS Kinetic and I intended on writing packages in Python when possible. This is a research project I am working on and I am very much a robotics novice so I am willing to try lots of solutions until I find something sufficient.
