Wireless Sensor Technologies for Automated Tracking and Monitoring of Construction Materials Utilizing Zigbee Networks

Overview This paper introduces Automated Material TRACking (AMTRACK) system architecture. To overcome the limitations in previous RFID- and GPS-based technologies observed in current construction practices, a new ZigBee-based localization technique with two different types of query and response pulses is presented for more accurate tracking performance. Feasibility study shows that accuracy with combination of RF and ultrasound is better than the one that uses only RF signal. AMTRACK can provide ZigBee-based monitoring capacity by embedding specific transducers into the system for various purposes of monitoring applications. Optimization of router placement and cost benefit analysis are examined to present research direction in the future.
