It shall not be forgotten, anyway, that the words ‘‘Internet”
and ‘‘Things”, when put together, assume a meaning
which introduces a disruptive level of innovation into today
ICT world. In fact, ‘‘Internet of Things” semantically
means ‘‘a world-wide network of interconnected objects
uniquely addressable, based on standard communication
protocols” [3]. This implies a huge number of (heterogeneous)
objects involved in the process.
