DEFINITIONS AND CHARACTERISTICS
• “The Internet of Things (IoT) is the network of physical objects -
devices, cars, buildings and other items - embedded with
electronics, software, sensors, and network connectivity that enables
these objects to collect and exchange data.” Wikipedia
• Characteristics of things
providing IP interface
connected to the Inter- or Intranet
fulfilling specific functions / roles
autonomous communication (without user interaction)

BARRIERS TO IOT
• Unreliable sensor networks, limited
resources on devices: power, memory
and CPU
• Deployment of IPv6
• Power for sensor network and its
bandwidth
• Agreement on Standards & Legislations
• Privacy & Security
• Identification
Connected devices are the basis of Internet of Things.
In this figure, we can see the number of connected devices worldwide from 2012 to 2020 (in billions). About 25% increasing every year.
Gartner estimated that the Internet of Things (IoT) would create revenue of $235 billion in 2016, up 22 percent from 2015.
IoT services are the real driver of business. End-users, organizations and vendors are becoming more interested in new IoT services.
Consumer usage will continue to account for the greatest number of connected things, while enterprise will account for the largest spending
In the enterprise, Gartner considers two classes of connected things: cross-industry devices and vertical-specific devices.
Cross-industry devices include connected light bulbs, building management systems that are mainly deployed for purposes of cost saving. The vertical-specific devices refer to specialized equipment used in hospital, container ships, and many others.
