Modelling and Control of S-MAC Based Wireless Sensor Networks Control System with Network-Induced Delay in Industrial

摘要

In view of the problems in the maintenance and deployment of wired sensor networks in industrial environment, this paper propose the application of wireless sensor networks to industrial control network. In consideration of the interference of the wireless sensor network and the obstruction of the barrier, a wireless sensor network model for multi hop wireless sensor is established based on S-MAC protocol, and the time delay is analysised for network model. Then, prove the stability of the controller by using the Lyapunov stability, finally gives the simulation. The simulation results show that the model is in line with the actual situation of the industry, and it laid a solid foundation for the establishment of wireless sensor network model in industrial control environment.
