Badly, UDPROS is unicast only. While it reduces the overhead over TCP, due to the unreliable connection, it can be improved to forward general information to a lot of robots. For 50 robots over the WiFi, while UDPROS will send 50 packets, it is possible to send only one broadcasted packet.
Again, this is only a proof of concept, to have a basic communication running. On this base, we can think about the problems encountered and how to tackle them and finally implement it inside ros_comm, for C++ and Python.
