Abstract
We consider a wireless control architecture where multiple sensors independently and randomly access a shared wireless medium to communicate with corresponding actuators, and we develop a decentralized channel access mechanism. Each sensor iteratively adapts the rate at which it accesses the medium in order to mitigate the effect of packet collisions from simultaneously transmitting sensors on its communication link. Control performance is abstracted as desired decrease rates of given Lyapunov functions for each loop, which translates to necessary packet success rates on each link. We provide theoretical conditions under which the decentralized mechanism converges to an operating point where performance of all control loops is met, and illustrate the approach in numerical simulations.
