Since the term Internet of Things (IoT for friends) was coined in 2009 at the well-known P&G conference by Kevin Ashton [1] Has rolled a lot of ink (and paper) on what is and especially, what is not.

To go straight to the point, IoT is the conjunction and evolution of M2M technologies [2] and WSN [3],  seasoned with the benefits offered by TCP/IP and the Web. Essentially, an IoT device is an electronic device centered on a microprocessor (or microcontroller) with access to various sensors and/or actuators, and with communications facilities to the outside through the use of some means of access, either direct or indirect, to the Internet.
