We study the problem of source localization as a multiple hypothesis testing problem, where each hypothesis corresponds to the event that the source belongs to a particular region. We use sequential hypothesis tests based on posterior computations to solve for the correct hypothesis. Measurements corrupted with noise are used to calculate conditional posteriors. We prove that the regional localization problem has asymptotic properties that allow correct detection almost surely in the limit of a large number of measurements. We present the Sense, Transmit & Test distributed algorithm that allows sequential sensing, communication and testing and we analyze the accuracy of this distributed algorithm and show that the test ends in a finite time. We also present numerical results illustrating properties of the suggested algorithm.
