摘要
采用目前算法对物联网传感器节点进行故障标定时,没有对节点信息进行聚类处理,导致算法存在虚警率高、计算复杂度高和标记范围小的问题。提出基于BDPCA聚类的物联网传感器节点故障标记算法,采用BDPCA聚类方法对物联网传感器节点信息进行聚类处理,并在聚类过程中对节点信息进行了零均值归一化处理。结合区分函数和区分矩阵在粗糙集理论的基础上对不同类别的节点信息进行知识约简处理,并通过贝叶斯决策理论实现物联网传感器节点的故障标记。实验结果表明,所提算法的虚警率低、计算复杂度低、标记范围广。
Recently,during the calibration of sensor node faults in the Internet of things,the traditional methods ignore the clustering of node information,resulting in a high false alarm rate,complex calculation,and narrow marking range.This paper proposes a fault marking algorithm for sensor nodes in the Internet of things based on BDPCA clustering.According to the BDPCA clustering method,the sensor node information of the Internet of things was clustered.Meanwhile,during the clustering process,the node information was normalized by zero mean.Based on the discernibility function and discernibility matrix,the node information of different categories was simplified.The fault marking of sensor nodes in the Internet of things was realized based on Bayesian decision theory.The results show that the algorithm has a low false alarm rate,simple calculation,and wide marking range.
