报告摘要

In the Cyber-Physical   System framework, sensors are deployed in some particular area to monitor   physical plants. Limited energy budget of the sensors is a crucial factor to   impact the performance of state monitoring on the physical plant. This talk   considers the scenario that a power-limited sensor sends the state   information of a physical plant to a remote estimator over a correlated block   fading wireless channel. From the perspective of system operator, it is of   importance to design a proper transmission power scheduling policy to achieve   desirable long-term estimation quality at the remote estimator side and save   the power cost at the sensor side concurrently. To achieve this objective, we   construct an optimization problem which minimizes the weighted sum of the   average estimation error and the average power cost in an infinite time   horizon. According to the Markov decision theory, we can derive the existence   of the optimal solution and its structure. Since an implicit part is existent   in its expression, the obtained optimal solution cannot be applied to control   the transmission power directly. To approximate the unclear part in the   optimal solution, we restrain the sensor power control policy and obtain a   close-form expression of this part. Then a suboptimal power scheduling   strategy with the explicit expression is presented.
