A multi-domain networking infrastructure enabling the situation-specific choreography of decentralized things

The Internet of Things (IoT) is a network between physical and virtual things, software services and people. The specific services these things offer to set up value-added chains are provided by the computer resources they use – like cloud computing for computationally intensive tasks or edge computing for real-time processing. Concepts such as the Digital Twin enable things to operate autonomously and connect independently. This leads to self-initiated systems which require the development of new infrastructure concepts to combine different computer resources and various Digital Twins. This paper proposes the Smart Systems Service Infrastructure (S3I) – a multi-domain networking infrastructure which allows things to choreograph themselves situation-specifically in highly decentralized and dynamic environments.
