“…Regarding component models and architectures supporting distributed dynamic systems such as CPS, different approaches related to self-adapting/self-organizing systems [23,24], self-managing architectures [25], component-based architectures [26,27], and architectural models at runtime [28] have been proposed. The common denominator of these approaches is the fact that they do not support high dynamicity (which does not scale with the ever-changing landscape of CPS) or they do not readily map to decentralized architectures.…”

Abstract. Developing software for dynamic cyber-physical systems (CPS) is a complex task. One has to deal with the dynamicity and unreliability of the physical environment where the software resides in, while, at the same time, provide sufficient levels of dependability and scalability. Although emerging software engineering abstractions, such as dynamic ad-hoc component ensembles, provide a convenient way to structure software for dynamic CPS, they need to be mapped to robust decentralized execution schemes in real-life settings. A particular challenge in this context is the robust distributed data dissemination in dynamic networks. Gossip-based communication stands as a promising solution to this challenge. We argue, that exploitation of application-specific information, software architecture in particular, has a large potential for improving the robustness and performance of gossip-based communication. This paper proposes a synergy between high-level architectural models and low-level communication models to effectively enable application-specific gossiping in component-based systems. The synergy is exemplified on the DEECo component model which is tailored to the needs and specifics of CPS, and evaluated on an emergency coordination case study with realistic network configurations.

“…We decided to use an approach that tackles adaptivity on the component level (refer to Peper and Schneider [2008]), although we would like to emphasize again that this is not mandatory for applying ConSerts. In correspondence with this approach, each component can have different configurations, which represent pre-engineered variants of the component that might be assumed during runtime.…”

In recent years it has become more and more evident that openness and adaptivity are key characteristics of next-generation distributed systems. The reason for this is not least due to the advent of computing trends like ubiquitous computing, ambient intelligence, and cyber-physical systems, where systems are usually open for dynamic integration and able to react adaptively to changing situations. Despite being open and adaptive, it is a common requirement for such systems to be safe. However, traditional safety assurance techniques, both state-of-the-practice and state-of-the-art ones, are not sufficient in this context. We have recently developed some initial solution concepts based on conditional safety certificates and corresponding runtime analyses. In this article we show how to operationalize these concepts. To this end, we present in detail how to specify conditional safety certificates, how to transform them into suitable runtime models, and how these models finally support dynamic safety evaluations.

Ad-hoc computer systems can automatically realize higher services when at least two distributed and communicating (embedded) devices come together. For this purpose, they must be able to manage appearance and loss of devices and resources, and they have to adapt to changes in requirements and environment. Based on a component-oriented approach for adaptive ad-hoc systems, this paper suggests a high-level service quality reference model to advocate further research on the quality matching problem between service provider and client components.
