This paper investigates the use of wireless sensor networks for estimating the location of an event that emits a signal that propagates over a large region. In this context we assume that the sensors make binary observations and report the event (positive observations) if the measured signal at their location is above a threshold; otherwise they remain silent (negative observations). Based on the sensor binary beliefs, a likelihood matrix is constructed whose maximum value points to the event… CONTINUE READING
