The authors study the problem of tracking an object that is moving randomly through a dense network of wireless sensors. They assume that each sensor has a limited range for detecting the presence of the object, and that the network is sufficiently dense so that the sensors cover the area of interest. In order to conserve energy the sensors may be put into a sleep mode with a timer that determines the sleep duration. They assume that a sensor that is asleep cannot be communicated with or woken up. Thus, the sleep duration needs to be determined at the time the sensor goes to sleep based on all the information available to the sensor.
