基于ZigBee的无线传感器网络

ZigBee-based Wireless Sensor Networks

提出一种基于Z igBee技术的无线传感器网络,该网络采用星型网络拓扑结构。为了降低每个传感器节点的功耗,同时延长传感器节点的寿命,采用STOP模式。在此模式下,传感器节点在低功率监测信道和定时周期性唤醒机制下工作,同时循环冗余校验CRC机制和加密算法的加入,更好地增加了系统的可靠性及安全性。

In this paper,a ZigBee-based wireless sensor network is proposed.It employs star topology.To reduce the power consumption of each sensor node and meanwhile to lengthen its life-span,we use the STOP model,only a very low power transmitter is used to monitor the channel when the sensor node is NOT waken up and the sensor node is wken up periodically.Furthernore,the security and reliability of the system are greatly improved because of the cyclic redundancy chek and the encryption algorithm's application.
