Design Method of Redundant Node in Zigbee Wireless Sensor Network

Abstract:

Redundancy technology is an important measure to enhance the reliability of computer control system. Two types of node redundancy architectures of wireless sensor network are analyzed. The design and implementing method of node redundancy in Zigbee network is presented. The node, which acts as master, is determined through competition after the system is powered up. The logical structure of the system is presented too. The switch protocol between master computer and backup computer and the method of competing for master among all the nodes are described in detail. The system can achieve that backup computer switches to master computer without disturbance. Because Zigbee network is adopted to achieve switching between Master and Backup, the reliability of the whole system is enhanced. The novel redundancy system is of low-cost, openness and good maintainability.
