According to analyst and media, in 2008, the number of connected devices surpassed connected people and it has been estimated that by 2020 there will be 50 billion connected devices which is seven times the world population. In fact, one of the most important elements in the IoT paradigm is Wireless Sensor Network (WSN). WSN behave as a digital skin, providing a virtual layer where the information about the physical world can be accessed by any computational system.
