摘要：
The increase in the application of Wireless Networked Control Systems (WNCS) in industrial automation motivates the study of the effect of mobility of WNCS nodes in the presence of noise. A WNCS system should satisfy certain end-to-end delay constraints, with all types of propagation, queuing, encapsulation/decapsulation and processing delays. Also, no data packets should be lost. These requirements should be met in the existence of 2.4GHz Industrial, Scientific and Medical (ISM) band interference. In this paper, an enhanced WNCS system is studied based on previous publications using unmodified Wi-Fi and Ethernet. The system is modified to include Sensor/Actuator mobility. A comparison between network and medium congesting interference in the presence of mobility is also presented and analyzed. Simulations are conducted on OPNET Network Modeler and all simulation results are subjected to a 95% confidence analysis. The system presented is shown to meet all control system requirements.
