Proxy-based Network Function to Assist Robotic Feedback Control System

This paper focuses on a remotely controlled feedback-based robotics system in a wide area network. Our use case is that a remote cloud server will aggregate advanced information processing functions for data measured by sensors and feedback to robotics devices for actuation. Network performance and Quality of Service (QoS) affects the stability of control. Therefore, we propose a proxy-based network function that allows the coexistence of service traffic flows for a robotics feedback control system with other services. We compared our approach with a case that did not apply our method by using simulation and showed the effectiveness of our proposed scheme.
