INTRODUCTION OF INTERNET OF THINGS :
The ability to link the physical world to the Internet and other data networks has profound implications for society and the economy. This Internet of Things makes it possible to monitor and manage operations thousands of miles away, track goods as they cross the ocean, or detect changes in the blood pressure of a diabetic that might be a sign of a
More than the next evolution of information technology, the Internet of Things redefines how we engage with the physical world and makes possible computer-mediated ways of doing business, managing public infrastructure, and organizing people’s lives that were not previously possible (see Box 1, “Defining the Internet of Things”). The full extent of
the changes this capability will bring about is impossible to gauge.
The internet of Things today
The Internet of Things is still in the early stages of growth. Every day more machines, shipping containers, infrastructure elements, vehicles, and people are being equipped with networked sensors to report their status, receive instructions, and even take action based on the information they receive. It is estimated that there are more than nine billion connected devices around the world, including smartphones and computers. Over the
next decade, this number is expected to increase dramatically, with estimates ranging from 25 billion to 50 billion devices in 2025.
Defining the Internet of Things :
We define “the Internet of Things” as sensors and actuators connected by networks to computing systems. These systems can monitor or manage the health and actions of connected objects and machines. Connected sensors can also monitor the natural world, people, and animals.
For the purposes of this research, we exclude systems in which all of the sensors’ primary purpose is to receive intentional human input, such as smartphone apps where the data input comes primarily through a touchscreen, or other networked computer software where the sensors consist of the standard keyboard and mouse.
