CPSS: A study of Cyber Physical System as a Software-defined Service

The Cyber Physical System (CPS) has become a promising direction that can enrich the interaction between people and people, people and objects, objects and objects in the physical world and the virtual world. Because of the development of CPS, the number and types of smart devices connected to the Internet have rapidly increased, bringing with it the current issues of scalability and efficiency of the Internet of Things(IoT) network. These problems are caused by the key mechanism of large-scale distribution to the Internet of Things network. In this article, we propose CPSS inspired by software-defined networking (SDN) and service oriented architecture, which is a powerful software-defined cyber physical system to solve the challenges of broader CPS adoption. To test CPSS, we develop a prototype system. Our experimental results show that CPSS can effectively control CPS, and CPSS has greatly improved latency and throughput compared to traditional controller-controlled CPS. (C) 2019 The Authors.
