A Cyber-Physical System (CPS) is defined as integrations of computation and physical processes. In CPS, downsized embedded devices monitor and manage the physical process. Mobile Internet Device (MID), as a portable handheld device designed for mobility providing a down-graded computing capability, can be used as a strong candidate for client-side devices in CPS. Since these physical devices have limited resources, it is not possible to execute complex computation and processes. To cope with this challenge, we apply Service-oriented Architecture (SOA) or Cloud Computing (CC) concepts to CPS, called a service-based CPS. To realize a service-based CPS, we first define overall architecture with three tiers. And, we present key methods to design each tier in the architecture. The design methods are defined to deal with design challenges of CPSs such as dynamic composition, dynamic adaptation, and high confidence CPS management. Then, we perform a case study to show applicability of our approach. With this approach, we hope that CPS can even handle complex and resource-consuming physical processes with a downsized MID.
