Quickest Change Detection of a Markov Process Across a Sensor Array

  title={Quickest Change Detection of a Markov Process Across a Sensor Array},
  author={Vasanthan Raghavan and Venugopal V. Veeravalli},
  journal={IEEE Transactions on Information Theory},
Recent attention in quickest change detection in the multisensor setting has been on the case where the densities of the observations change at the same instant at all the sensors due to the disruption. In this work, a more general scenario is considered where the change propagates across the sensors, and its propagation can be modeled as a Markov process. A centralized, Bayesian version of this problem is considered, with a fusion center that has perfect information about the observations and… CONTINUE READING
