Data Transmission Method for Sensor Devices in Internet of Things based on Multivariate Analysis

Abstract In this paper, tree diagrams and symbols in visualization technology are selected to display the security status of sensor networks, and fully mine the micro-details of the network through multi-dimensional display of monitoring target status. Time series maps are used to predict the operation trend of sensor networks in eight dimensions, and analyze network attack modes combined with image characteristics to evaluate the security situation of the Internet of Things. On this basis, a centralized wireless routing method is adopted to find the optimal path from all the sensing nodes to sink, which ensures that the sum of links’ average transmission times of the optimal path and the minimum energy consumption of data transmission are the minimum. The results show that this method can identify the state of sensor network and discriminate attack modes, and has less data transmission times and low energy consumption.
