The document defines Internet of Things (IoT) as connecting physical objects through internet connectivity, allowing these "things" to sense and collect data and operate. It discusses how IoT has evolved from connecting computers to now connecting various physical objects and devices through technologies like sensors and RFID tags. The document also outlines some key aspects of IoT like its history starting at MIT, ubiquitous networking to enable interactions between connected things, how things/objects are defined as smallest addressable units called atoms, use of identifiers instead of IP addresses, applications of IoT in areas like smart cities and agriculture.

3. What is Internet of Things?
“from a network of interconnected computers to a network
of interconnected objects”, European Commission
“The basic idea of the IOT is that virtually every physical thing in this world can
also become a computer that is connected to the Internet ”, AutoID Labs
“IoT is simply the point in time when more “things or objects”
were connected to the Internet than people”, Cisco Systems

4. “A world-wide network of interconnected objects uniquely addressable,
based on standard communication protocol.” Tata Consultancy services

5. History of IoT
• Originally introduced by the Auto-ID
research center at the MIT
• A “thing” or “object” is any possible item
in the real world that might join the
communication chain
• Main objective of the IoT was to combine
the communication capabilities

6. characterized by data transmission

7. History of IoT
• Ubiquitous Networking
– To provide tasks and process automation,
new services will be developed
– Developed around machine-to-person,
machine-to-machine or thing-to-thing and any
other possible interactions

9. Ubiquitous Networking

12. Objects/Things in IoT
• In close-to-market IoT applications, RFID tags
and sensors are connecting inanimate
objects
• These objects are building the actual
things enabling the first IoT services
• As per the American Auto ID research
center description of the IoT and the
European CASAGRAS research project

13. terminology,
• “things” or “objects” are described as a set
of atoms

14. Objects/Things in IoT
• Atom is the smallest object in the IoT

17. Identifier in IoT
• IP addresses identify nodes in the Internet
and serve as locators for routing
• IPv6 allows larger address space than IPv4
• Term “identifier” is similar to the term
“name”
• A name does not change with location

18. in contrast to an “address”
• IP addresses are used to route
packets between end-systems
