Complexity
In semi-open or closed loops (i.e. value chains, whenever a global
finality can be settled) IoT will often be considered and studied as a
complex system due to the huge number of different links, interactions
between autonomous actors, and its capacity to integrate new actors. At
the overall stage (full open loop) it will likely be seen as a chaotic
environment (since systems always have finality). As a practical
approach, not all elements in the Internet of things run in a global,
public space. Subsystems are often implemented to mitigate the risks of
privacy, control and reliability. For example, domestic robotics
(domotics) running inside a smart home might only share data within and
be available via a local network. Managing and controlling high dynamic
ad hoc IoT things/devices network is a tough task with the traditional
networks architecture, Software Defined Networking (SDN) provides the
agile dynamic solution that can cope with the special requirements of
the diversity of innovative IoT applications.
