Abstract: As the internet of things (IoT) becomes more popular, supporting systems and their components become more complex and largely heterogeneous. This paper discusses on a system of systems (SoS) architecture for IoT systems composed by autonomous components. The proposed architecture focuses on a middleware transforming sensor services to REST services, for the development of mixed-criticality applications. The middleware consisting of autonomous aggregation software running on commodity multi-core devices, such as Raspberry Pi. Self-management policies applied are discussed in the paper. The analysis of a smart building system, developed as a use case, provides solid evidence that such an architecture is realistic and can lead to highly competitive systems.

Keywords: internet of things; IoT; system of systems; SoS; edge devices; aggregation software; autonomous components; self-management policies.
