基于无线传感网的工业人机交互网络移动接入与动态路由机制研究

The development of wireless sensor network provides a solid foundation for the network and mobility support of industrial human-machine interaction. In the industrial human-machine interaction network, the co-existence of mobile human nodes and heterogeneous machine nodes has brought new challenges for the mobile access and dynamic routing mechanisms design in wireless sensor networks. This project aims at supporting the demands of industrial human-machine interaction. In order to solve the adaptability problems of mobile human nodes and heterogeneous machine nodes, we explore the characteristics of industrial human-machine interaction, and propose new mechanisms for mobile access and dynamic routing in the industrial human-computer interaction. The research details are given as follows: 1) According to the industrial field investigation, we will build the industrial human-machine interaction network model based on random geometric graphs, which can describe the heterogeneous and movement characteristics of the network. 2. To meet the demands of “face to face” connection from human node to machine nodes, we design an adaptive algorithm for mobile access based on the difference of the signal strength that nodes received. 3. To meet the transmission requirements that the machine nodes have to send alarm information to human nodes, we analyze the movement characteristics of human nodes, and design dynamic routing based on the footprints of human nodes. The project will provide theoretical and technical support to develop industrial internet from the perspective of industrial human-machine interaction.
