In the software defined Internet of Things (IoT), multi-source heterogeneous data comes from different devices and has different formats, structures, and qualities, which increases the complexity of feature detection. Therefore, a mixed attribute feature detection method for multi-source heterogeneous data in software defined IoT is proposed. Using the joint Kalman filtering algorithm to fuse multi-source heterogeneous data in the software defined Internet of Things, completing the initial integration of heterogeneous data. Combined with evidence classification algorithms, network data with the same mixed attributes are divided into the same dataset to achieve classification of multi-source heterogeneous data. Based on the inverse similarity characteristics of multi-source data, an edge operator calculation method is introduced to split the classified data attribute features, and combined with support vector machines, accurate detection of multi-source heterogeneous data attribute features is achieved. The experiment shows that the covariance calculation results of the proposed method are always below 0.15, and the distinction between different attribute features is more obvious, with a detection probability of over 0.8. This method can achieve precise partitioning of mixed attributes of multi-source heterogeneous data in software defined IoT.
软件定义物联网(Software defined Internet of Things,SD-IoT)通过软件定义理念的引入,使物联网系统的功能和性能可以通过软件灵活配置和扩展。在SD-IoT框架下,多源异构数据的处理和分析显得尤为重要[1]。多源异构数据大多来自不同的设备、系统和网络,具有不同的结构、格式和语义,如何对其实施统一处理与特征检测,是软件定义物联网面临的重要任务。
