ZigBee技术是实现无线传感器网络的重要技术手段之一，其中，Z-Stack协议栈是TI公司推出的一种实现ZigBee技术的软件架构，已被广泛使用。以CC2530为硬件平台，Z-Stack协议栈为软件平台，通过对Z-Stack协议栈的分析研究，指出了现有的Z-Stack协议栈在实际应用条件下存在的功耗问题，提出了相应的节能算法：针对终端节点的功率优化调节算法和针对路由器节点的低功耗算法，并通过实验进行验证。实验结果表明，与原始的Z-Stack协议相比，本文提出的基于Z-Stack协议栈的节能算法可以有效地减少节点在工作过程中的能耗，从而提高网络的整体寿命。

ZigBee technology is one of the important techniques for wireless sensor network. Among the implements of ZigBee,Z-Stack is one of the software architecture released by TI Corporation,which has been widely used. The article used CC2530 as hardware platform and Z-Stack as software platform to analyze Z-Stack. It points out that there is power consumption issue on current Z-Stack in practical use. The corresponding power-saving algorithms are also put forward. They are power optimization algorithm for end-device nodes and low power consumption routing al-gorithm for router nodes. Both algorithms are verified by experiments. The results show that the power-saving algo-rithms based on Z-Stack proposed in the article can save power consumption effectively when the nodes work and then improve the overall life of the network.
