Review of Cyber-Physical System Architecture

With the goal of accomplish the ubiquitous intelligence in social life, Cyber-Physical Systems (CPS) are getting growing attentions of researchers and engineers. However, the complexity of computing and physical dynamics bring a lot of challenges in the development of CPS, such as integration of heterogeneous physical devices, system verification, security assurance, and so on. A general or unified architecture plays an important part in the process of CPS design. In this paper, we review the current and previous works of CPS architecture, and introduce the main challenges and techniques of architecture development : real-time control, security assurance, integration mechanism. Then we propose a general CPS architecture based on Service-Oriented Architecture (SOA), the main advantage of this proposed architecture is the integration flexibility of services and components. At the end, we introduce the typical applications of CPS, and suggest the future research areas.
