Abstract

We present the concept of runnable virtual nodes as a means to achieve predictable integration and reuse of software components in cyber-physical systems. A runnable virtual node is a coarse-grained real-time component that provides functional and temporal isolation with respect to its environment. Its interaction with the environment is bounded both by a functional and a temporal interface, and the validity of its internal temporal behavior is preserved when integrated with other components or when reused in a new environment. Our realization of runnable virtual nodes exploits the latest techniques for hierarchical scheduling to achieve temporal isolation, and the principles from component-based software-engineering to achieve functional isolation. In the paper we present a proof-of-concept case study, implemented in the ProCom component-technology executing on top of FreeRTOS based hierarchical scheduling framework.
