基于Z-Stack协议栈的WSN能量管理策略

Energy Management Strategy for WSN Based on Z-Stack

在分析基于ZigBee协议的Z-Stack1.4.3协议栈基础上,实现无线传感器网络(WSN)数据的自动周期获取,通过设置协议栈中休眠条件,不仅能最大限度地降低功耗,而且可以保证网络的同步性。构建一个簇树结构的低功耗ZigBee网络,设计具有网络数据、拓扑显示等功能的监控管理系统。应用结果表明,该系统能在低功耗下稳定地工作,完成环境数据监测。

By analyzing ZigBee compliant Z-Stack 1.4.3 release,this paper obtains the periodic data from Wireless Sensor Network（WSN）.Setting the sleep conditions properly not only minimizes the energy consumption but also satisfies synchronization of WSN.Energy efficient WSN are constructed with tree topology and the management software is developed to provide the function of displaying of dynamic data of sensors and energy of nodes,monitoring the network topology,etc.Application results show the system can run reliably under the condition of low power consumption and realize the monitoring of environmental data.
