Abstract :
This paper investigates the use of a sensor network for detecting the presence of an event. The sensors monitor the signal emitted from the source and report the existence of the event when the received signal strength is above a certain threshold. In this paper, we derive analytical expressions for the probability of false alarms and the probability of no detection as functions of the threshold. Subsequently, we determine the optimal threshold that trades off the probability of false alarms and the probability of no detection
