摘要： 作为智慧物联网的关键技术支撑,无线传感器网络在实践应用时,应利用时间同步将一致性的参考时间标准提供给节点,从而使无线传感器网络节点所获取的数据具有较高的精确性。文章主要介绍了经典点对点双向型同步算法、单向型贝叶斯估计同步算法两种不同的算法,设置相应的实验工况,开展实验数据分析工作,以此来对照研究两大算法是否实现了同步,并分析同步效果优越性。结果发现两种不同算法均达到同步,但是单向型贝叶斯估计同步算法更优化。

Abstract: As a key technical support of the intelligent Internet of Things,the wireless sensor network should use the time synchronization to provide the consistent reference time standard to the nodes in time application,so as to make the data obtained by the wireless sensor network nodes have high accuracy.This study mainly introduces two different algorithms,classical point-to-point two-way synchronization algorithm and one-way Bayesian estimation synchronization algorithm,to set the corresponding experimental conditions and carry out experimental data analysis to study whether the two algorithms achieve synchronization and analyze the superiority of the synchronization effect.It is found that both different algorithms achieve synchronization,but the one-way Bayesian estimation synchronization algorithm is more optimized.
