The new advances in sensor device technologies make Wireless Sensor Networks (WSNs) effective and economically viable solutions for a large variety of applications. Extensive research efforts have been devoted to various WSN research topics, such as target tracking, data collection and dissemination, localization, and sensing. In this paper, we focus on target tracking problems using WSN – one of the most challenging WSN research topics because of certain real-time constraints, energy consumption, and detection accuracy. We propose an intelligent and independent decision making strategy for sensors to monitor targets in an active environment. This algorithm has the following objectives: 1) Dynamically duty-cycle sensor devices to go to sleep in order to save energy; 2) Quickly wake up sensor nodes to ensure detection accuracy. We illustrate and analyze the details of this algorithm, and demonstrate its performance in terms of WSN lifetime with leader based algorithm.
