The human dependence on machines is increasing for almost every human activity for error-free decisions, control, information generation and distribution, and ultimately for improving human lives. This trend requires networking of the machines, appliances, devices and objects (“things”) for exchanging information between machine-to-machine and machine-to-humans.
The Internet is the most successful, innovative and massive network ever created by humans. In the 90s, people started using the Internet to share information and knowledge via the World Wide Web, which is generally considered the first generation of Internet. Internet 2.0, which is ongoing now, is the platform for social networking. It is expected that the next revolution, Internet 3.0, would be the interconnection of every possible addressable object on planet Earth, creating a new Internet called the ‘Internet of Everything’.
