摘要
研究了节点分布具有不连续性的无线传感器网络的时钟同步问题,分析提出了一种基于时间戳的时钟同步算法,对算法的实现及性能进行了实验验证和评估。实验结果表明基于时间戳的无线传感器网络时钟同步算法可以获得毫秒级的同步精度,可以满足无线传感器网络的大多数实际应用。
To implement synchronization for the wireless sensor networks with indirect connectivity, the clock synchronization mecha- nism for wireless sensor networks was thoroughly analyzed. A kind of clock synchronization algorithm based on time-stamp scheme was pres- ented. Then it was studied and evaluated in detail. Experiments indicated that the proposed clock synchronization algorithm based on time- stamp was energy-effective, which was able to obtain a synchronization precision of one millisecond in order of magnitude, which can satisfy most of the practical applications of wireless sensor networks.
