What is
IOT?
 The Internet of Things is the network of physical objects or
"things" embedded with electronics, software, sensors, and
network connectivity, which enables these objects to collect
and exchange data.
 It 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 economic benefit.

"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 rescue operations.
These devices collect useful data with the help of various existing
technologies and then autonomously flow the data between other devices.

Example
▶ General Electric (GE) deploys sensors in its jet
engines, turbines, and wind farms. By analyzing data
in real time, GE saves time and money associated with
predictive maintenance.

History of
IoT
The concept of the Internet of Things first became popular
in 1999, through the Auto-ID Center at MIT and related
market- analysis publications.
Radio-frequency identification (RFID) was seen as a
prerequisite for the IoT at that point. If all objects and
people in daily life were equipped with identifiers,
computers 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, blue-tooth, and digital watermarking.

How IOT
Works?
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
capabilities include:
Communication and cooperation
Addressability
Identification
Sensing
Actuation
Embedded information processing
Localization
User interfaces

The Structure of
IoT
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 “smart devices.”
Thinking Things : Embedded intelligence in devices
through sensors has formed the network connection to the
Internet. It can make the “things” realizing the intelligent

Sensors in even the holy
cow!
In the world of IoT, even the cows will be connected
and monitored. Sensors are implanted in the ears of
cattle. This allows farmers to monitor cows’ health and
track their movements, ensuring a healthier, more
plentiful supply of milk and meat for people to
consume. On average, each cow generates about 200
MB of information per year.

TECHNOLOGICAL CHALLENGES OF
IOT
At present IoT is faced with many
challenges3, 1
such as:
Scalability
Technological Standardization
Inter operability
Discovery
Software complexity
Data volumes and interpretation
Power Supply
Interaction and short range communication
Wireless communication
Fault tolerance

Scholars and social observers and pessimists
have doubts about the promises of the
ubiquitous computing revolution, in the areas
as:
Privacy
Security
Autonomy and Control
Social control
Political manipulation
Design
Environmental impact
Influences human moral decision making
