title = "Decentralized Bayesian detection with feedback",
abstract = "A decentralized detection system with feedback and memory using the Bayesian formulation is investigated. The optimization of this system results in a likelihood ratio test at the local detectors for statistically independent observations. In addition, local detector thresholds and the system probability of error are shown to be a function of the fed back global decision. The issue of data transmission between local detectors and the fusion center is addressed. Two protocols are proposed and studied to reduce data transmissions. Numerical examples are also presented for illustration.",

note = "Funding Information: Recently, the idea of feedback in decentralized detection systems without memory has been considered in [2]-[5]. In these systems, the fusion center fed its decision to each of the local detectors. A local detector of these systems operated on the previous global decision and its current observation sample. In this paper, we investigate a decentralized detection system with feedback and memory using the Bayesian formulation. In this system, the global decision is fed back to all the local detectors. A local detector operates on its current observation, its previous observations and the received global decision to yield a local decision as shown in Fig. 1. A detailed description of this system is given in Section 11. In Section 111, we formulate the Bayesian hypothesis testing problem for this system.
