Towards an Infrastructure Model for Composing and Reconfiguring Cyber-Physical Systems

Abstract

Cyber Physical Systems involve the use of different computing, communication and control technologies and require satisfying simultaneously several restrictive constraints. One characteristic of CPS is that there is a constant evolution of technologies and tools that help designers to design this kind of systems. Due to its complexity, middleware architectures are frequently used to implement CPS. Most of these middleware architectures tend to use models of the software entities of the system. However, quite often, they do not consider the infrastructure (hardware and network) over which these systems are executed even though this is a key issue for these systems. In addition, frequently, it is necessary to make some composition and reconfiguration decisions at run-time over the current status of the infrastructure. This work proposes a model developed within the iLAND project that represents the static and operational status of the CPS infrastructure.
