**2. The M2X Economy**

The evolving M2X applications and the corresponding ecosystem will influence our daily lives in many ways. Besides M2M interactions, machines interact with humans (M2H) or infrastructure components (M2I). The framework of the M2X Economy represents a more general view on use cases that involve autonomous smart devices and also encompasses M2M, M2H, and M2I scenarios [1].

In Section 2.1 we first present the running case that is used for illustration purposes throughout this work. Afterwards, Section 2.2 introduces related concepts such as cybernetics, IoT, cyber-physical systems (CPS), and wireless sensor networks (WSNs) as well as related work. Next, is the definition and elements of the M2X Economy in Section 2.3.
