一种基于网线传感器网络的数据补全算法
A Novel Algorithm for Completion of Missing Data in Wireless Sensor Networks
摘要
Abstract
In recent years,wireless sensor networks are widely used to promote the development and progress of human social life. Howev-er,the limitations of WSN and the influence of distribution environment conditions result in that the perception data of WSN exists prob-lems about abnormality and loss which seriously affect the WSN application. The full complement of missing data still needs to be re-solved. In wireless sensor networks,the method used in data completion mainly considers about the time correlation or spatial correlation, and only can estimate a single missing data attribute,but it fails to estimate multiple attributes of data samples. For this problem,an im-proved Ioptspace algorithm based on OptSpace is put forward to solve the problem. This algorithm,simultaneously considering both time and spatial correlation,fully complements data collected by the sensor network as a matrix. Experiments show that compared with the data completion method of linear interpolation and spatial correlation,the estimation effect and accuracy of Ioptspace algorithm is better.关键词
