摘要：AbstractThis paper investigates the scheduling problem over a delayed channel. Different from most existing documents, a novel hybrid model is proposed which combines both delay and packet-loss to minimize the error covariance update at the estimator side. With the help of this setup, a co-design problem between power consumption and estimation performance is considered. We first derive out a globally optimal off-line schedule. Moreover, an on-line schedule based on a designed threshold is proposed to further enhance the performance, which is aided by feedback information. Comparisons between on-line and off-line strategies are illustrated by numerical simulations, which has shown the superiority of on-line one to the off-line one.
