It is happening. Everyday more and more objects (mostly sensors so far) are connected to the Internet. We have only to take a look at Pachube as an example, to be aware about what we are talking about. They started just five years ago with the idea of providing a place where people can send information generated by their sensors and share information. Now they have hundreds of thousands of feeds. “I have no connection, nor interest in Pachube, but I take them as an example of what is happening”, says Roberto Saracco, IEEE Communications Society Senior member. It is getting easier and easier to have more objects connected to the Internet, as there is a growing interest in sharing data.
Saracco explains in this article found in the IEEE Communications Society Blog, his point of view on this phenomenon.

The Internet of Things is a “gradual revolution that will lead to all the objects surrounding us being connected to the Internet in some way”. This is one of the the main ideas containing at the report about The Evolution of the Internet of Things recently presented by Casaleggio Associati, a consultancy on Internet strategy and research on the digital economy in Italy.
According to its point of view of Casaleggio Associati the report identifies five stages in this Internet of Things evolution process that they have named:
- The world is the index: objects are identified by their position in the world
- Take the world online: moving onjects uniquely identified by a code
- Take control of the world: the objects are connected to the Internet and interact with people
- Let the things talk to each other: objects communicate with each other and action each other to occurrance of certain conditions
- Let things become intelligent: objects communicate with the Net to which they provided information that can be elaborated and used as new knowledge
In order to get an idea of how technology has evolved in the last few years regarding to the IoT, te report presents a summary of Internet-connected products developed in each of these stages. It also explains how each product works and the technologies used.
The report concludes that the main challenge is to create and develop technologies that integrate the two basic factors for merging objects and the Internet, “energy” and “connectivty”. This goal would make possible to think on new products connected to the Internet in the future, because currently the applications are being targeted mostly to mobile phones, due to their capabilities regarding power and connectivity everywhere.
