摘要 对于几乎所有无线传感器网络应用来说,时间同步是非常重要的.由于无线传感器网络的多节点、低功耗等特点,一种合适的时间同步算法的实现尤为关键.以自主研发的硬件平台为基础,设计并实现了一种适用于Zigbee无线通信协议的单跳和多跳网络的时间同步算法,并给出了详细的算法分析及实现流程.实验结果表明所提出的时间同步算法在Zigbee单跳及多跳信标网络中均有良好的性能表现,满足了Zigbee协议低功耗、高同步精度的要求,在实现Zigbee休眠节能机制的同时,算法达到了较高的时间同步精度. Time synchronization is essential for almost all the wireless sensor network application. Because of the multi-nodes and low energy consumption feature of wireless sensor network, the realization of a proper time synchronization algorithm is especially important. Based on a self- developed hardware platform, an appropriate single-hop and multi-hop time synchronization algorithm of Zigbee protocol is presented and a detailed algorithm analysis and implementation flow are given. The experimental results show that the time synchronization algorithm has a favorable performance in the single-hop and multi-hop beacon networks,which ensures a high synchronization accuracy and the low power consumption. At the same time of implementing Zigbee energy-saving mechanism, the algorithm provides high synchronization.
