T he ability to detect events of interest is essential to the success of emerging sensor network technology. Detection often serves as the initial goal of a sensing system. Indeed the presence of an object has to be ascertained before a sensor network can estimate attributes such as position and velocity. For systems observing infrequent events, detection may be the prevalent function of the network. Furthermore, in some applications such as surveillance, the detection of an intruder is the

In the setting where local sensors preprocess observations before transmitting data to a fusion center, the corresponding decision making problem is termed decentralized detection.
