Abstract
We consider a wireless control system where multiple power constrained sensors transmit plant output measurements to a controller over a shared wireless medium. A centralized scheduler grants channel access to a single sensor on each time step. Assuming an a priori designed controller, we design scheduling and transmit power policies that opportunistically adapt to the random wireless channel conditions experienced by each sensor. The objective is to obtain a stable system, by minimizing the expected decrease rate of a given Lyapunov function, while respecting the sensors' power constraints. We develop an online optimization algorithm based on the random channel sequence observed during execution which converges almost surely to the optimal protocol design.
