to several models in order to facilitate getting acquainted with the concepts
defined in the respective model by tying their understanding together with a
common, ―Red Thread‖. We hope that this application of the use case helps
with understanding the different models. We are aware of the complexity of the
IoT Domain Model and the Trust, Security, and Privacy issues, but this
complexity is inherent in the domain of the Internet of things itself. It is however
crucial to really understand the models introduced in this chapter, before
moving on.
The next Chapter 4 , the IoT Reference Architecture, builds upon this foundation
and details it even further, so that concrete IoT-compliant architectures can be
derived. The section uses several ways of projecting the IoT Reference
Architecture, and it also presents several ―Views‖ that complement the different
models presented in this section. For instance, we propose Functional
Components, which relate to the IoT Functional Model and the IoT
Communication Model, in the Functional View (see Section 4.2.2) that we
discussed in this chapter. We also provide an Information View, which tightly
relates to the IoT Information Model discussed in this chapter.
