Distributed Fusion Estimation in the Presence of Measurement Quantization and Mixed Attacks
摘要
This paper addresses the distributed fusion estimation problem of stochastic signals from quantized measurements with random parameter matrices and time-correlated additive noises. These measurements are assumed to be exposed to mixed network attacks, including both random deception attacks and denial-of-service (DoS) attacks and the stochastic nature of these attacks is aptly modeled by Bernoulli random variables. Using a covariance-based methodology and a prediction compensation strategy to counteract the random loss of information caused by DoS attacks, recursive algorithms are designed for the distributed fusion filtering and fixed-point smoothing problems.
