Runtime Safety Models in open Systems of Systems

Upcoming application domains, from Ambient Assisted Living to Car2Car, show the need for openness, flexibility and safety in next generation embedded systems. Whilst there are several approaches tackling the dynamic reconfiguration and integration of components, there has not been much research done on safety of such systems. As many of the application domains are inherently safety critical this hinders open systems of systems to unfold their full potential. Models at runtime have shown to foster dynamic adaptation of software systems. In a similar way, the integration of appropriate runtime safety models and dynamic evaluation mechanisms into systems seems to be a viable approach to enable safety management at runtime. In this paper we sketch out our modeling approach for adaptive ad hoc systems and present first results with respect to the integration and usage of safety models at runtime.
