Study of Distributed Detection Based on N-P Rule with Correlated Sensors

We study the fusion algorithms of distributed detection based on Neyman-Pearson criteria with correlated condition. We consider a parallel network structure that consists of a number of local sensors and a fusion center.Each sensor makes a binary deci- sion based on its own observation.The detections with known and unknown joint pdf are considered.In both cases,we give the theoreti- cal derivation of optimal fusion rules and corresponding solution.In the end,some useful conclusions are given based on the experi- ment.
