What is IoT?
3
The Internet of Things (IoT) is the network of physical
objects or "things" embedded with electronics, software,
sensors, and network connectivity, which enables these
objects to collect and exchangedata.
IoT allows objects to be sensed and controlled
remotely across existing network infrastructure, creating
opportunities for more direct integration between the
physical world and computer-based systems, and resulting
in improved efficiency, accuracy and economicbenefit.

4.
"Things," in the IoT sense, can refer to a wide variety
of devices such as heart monitoring implants, biochip
transponders on farm animals, electric clams in coastal
waters, automobiles with built-in sensors, DNA analysis
devices for environmental/food/pathogen monitoring or
field operation devices that assist fire-fighters in search
and rescueoperations.
These devices collect useful data with the help of
various existing technologies and then autonomously flow
the data between otherdevices.

5.
The concept of the Internet of Things first became
popular in 1999, through the Auto-ID Center at MIT and
related market-analysis publications. R
Radio-frequency identification (RFID) was seen as a
prerequisite for the IoT at that point. If all objects and
5
people in
computers
daily life were equipped with identifiers,
could manage and inventory them. Besides
using RFID, the tagging of things may be achieved through
such technologies as near field communication, barcodes,
QR codes, bluetooth, and digitalwatermarking.
History of IoT

How IoT Works?
6
Internet of Things is not the result of a single novel
technology; instead, several complementary technical
developments provide capabilities that taken together help
to bridge the gap between the virtual and physical world.
These capabilitiesinclude:
 Communication and cooperation
 Addressability
 Identification
 Sensing
 Actuation
 Embedded information processing
 Localization
 User interfaces

Why IoT Attractive?

11.
The Structure of IoT
21
The IoT can be viewed as a gigantic network
consisting of networks of devices and computers
connected through a series of intermediate technologies
where numerous technologies like RFIDs, wireless
connections may act as enablers of this connectivity.
 Tagging Things : Real-time item traceability and addressability
by RFIDs.
 Feeling Things : Sensors act as primary devices to collect data
from the environment.
 Shrinking Things : Miniaturization and Nanotechnology has
provoked the ability of smaller things to interact and connect
within the “things” or “smartdevices.”
 Thinking Things : Embedded intelligence in devices through
sensors has formed the network connection to the Internet. It
can make the “things” realizing the intelligentcontrol.

Interoperability

14.
IoT as a Network of Networks:
These networks connected with added security, analytics, and
management capabilities. This will allow IoT to become even
more powerful in what itcan help peopleachieve.

Knowledge Management –
Turning Data into Wisdom
11
The more data that is created, the better understanding and
wisdom people canobtain.
