摘要: 出了基于层次结构的无线传感器网络时间同步协议。首先以汇聚点为根节点建立一个具有层次结构的树,然后采用成对同步法沿着该树建立一个全网统一的时钟。仿真结果显示该协议能满足无线传感器网络的时间同步要求。

Abstract: A time synchronization protocol based on hierarchical structure was designed. In this protocol, at first a hierarchical structure tree was established with sink node as root node, then a pair wise synchronization was performed along the tree to establish a global timescale throughout the sensor network. The simulation results show that the time synchronization protocol can be used for wireless sensor network applications.

Key words: wireless sensor networks, time synchronization, pair-wise synchronization
