Abstract:

We consider a remote state estimation problem where, at each discrete time instant, a wireless sensor has several different communication channels to choose from. These channels are unreliable and introduce random packet dropouts in the communication between the sensor and the remote estimation system. To achieve satisfactory estimation performance, the best channel needs to be selected. A key difficulty of the situation at hand is that the channel dropout probabilities are unknown. We study the case where both learning of the channel reception probabilities and state estimation are carried out simultaneously. Methods for choosing the channels based on techniques for multi-armed bandits are presented and shown to ensure stability of the remote estimator. Furthermore, we define the performance notion of estimation regret, and derive bounds on how it scales with time for the considered algorithms.
