Abstract: To reduce the delay of data transmission and improve the transmission efficiency in the network communication of traditional dam monitoring system due to channel scan and queuing, we propose an optimized method of ZigBee networking integrated with Fuzzy Analytic Hierarchy Process (FAHP). Firstly we built a dam monitoring transmission network, and then calculated the weights of transmission nodes by using FAHP, based on which we analyzed the nodes’ efficiency and transmission orders in the network. Finally, we completed the optimization by resetting networking structure and data transmission path. Results of both simulation and engineering application in Weishui monitoring project indicate that the proposed method is able to improve monitoring time and data transmission efficiency and is suitable for network optimization of nodes in various monitoring systems.

Key words: dam monitoring, FAHP, ZigBee networking, transmission delay, priority rating
