What is it about?
WiFi is great, but has the potential of lag in communication and also unreliable. For teams of robots o IoT devices such limitations are important. We implement a protocol over the most common and vanilla WiFi to create reliable communication even under conditions in which the channel is under attack.

Why is it important?
There are many robots in human environments that are tele-operated or in teams of robots and because they are mobile they need communication to their human pilot to other robots. Such communication is over WiFi because it is readily available, but it could be catastrophic in communication is not reliable. We enable reliable (low latency) for teams of robots or for tele-operation in standard WiFi.
Perspectives
More and more robots will be mobile in human environments where WiFi is the wireless communication. We need to make sure that there is little lag in such communication.
