摘　　要：常规方法提取传输数据主频特征时,提取对象为随机传输信道的信息流,导致数据传输速率较慢,为此,提出了基于数学统计模型的物联网资源数据传输效率建模方法.首先利用数学统计模型定量描述数据特征矢量与数据属性值之间的关系,并将特征矢量相近的资源数据归纳到同一分类平面,封包传输平面中的同类资源数据,解析同类资源数据中包含的信息,以此为基础定位数据分类封包传输信道.然后从提取上述信道中的单分量信号结构,通过单分量主频特征分配数据传输动态任务.最后结合任务量和数据包概率密度,建立数据传输效率模型.将物联网资源数据包大小、网络簇头节点数据作为测试条件,设置对比实验.结果表明,设计方法选择的最优数据传输格式传输数据时,数据发送速率和数据接收速率明显优于常规方法,为数据传输格式的选择提供更高参考价值.Aiming at the problem of slow data transmission rate due to the information flow of the random transmission channel as the extraction object when the process of extracting the main frequency characteristic of the transmission data by the conventional method is performed.Therefore,a modeling method of resource data transmission efficiency of the internet of things based on mathematical statistical model is proposed.Firstly,the mathematical statistical model is used to quantitatively describe the relationship between the data feature vector and the data attribute value,and the resource data with similar feature vectors are summarized into the same classification plane.The similar resource data in the packet transmission plane and the information contained in the similar resource data is analyzed.On this basis,the data transmission dynamic tasks are allocated through single-component main frequency characteristics of single-component signal structure extracting from the aforementioned channel.Finally,a data transmission efficiency model is established based on the task volume and packet probability density.Take the internet of things resource packet size and network cluster head node data as test conditions,and set up comparative experiments.The results show that the data transmission rate and data reception rate are obviously better than the conventional method when the optimal data transmission format selected by the design method transmits data.It provides a higher reference value for the choice of data transmission format.
