Powered by digital transmission advances in recent years, Wireless Sensor Networks (WSNs) are beginning to experience a boom in different areas. Of special interest are those applications offering real-time tracking and monitoring of objects in motion, both indoors and outdoors. A WSN can have a large number of nodes, each with multiple neighbor nodes. These nodes work together to create a self-configuring mesh that can efficiently achieve a common objective. In this paper, the authors focus on the accuracy of intruder tracking and monitoring, when relying on low-cost binary detection sensing mechanisms.
