Abstract
A decentralized sequential detection problem is considered in which
each one of a set of sensors receives a sequence of observations about
the hypothesis. Each sensor sends a sequence of summary messages to
the fusion center where a sequential test is carried out to determine
the true hypothesis. A Bayesian framework for this problem is
introduced, and for the case when the information structure in the
system is quasiclassical, it is shown that the problem is tractable.
A detailed analysis of this case is presented along with some
numerical results.
