3. INTRODUCTION
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 exchange data.

4. HISTORY OF IOT
• The concept of the Internet of Things first became popular in 1999
invented by kevin Ashton, 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.

5. 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

7. DEVICE LAYER
Provides a user interface for using IoT.
Different applications for various sectors like Transportation,
Healthcare, Agriculture, Supply chains, Government, Retail etc.
Devices and sensors used are:
GPS
Gyroscope
Accelerometer
Wifi
Ethernet
Bluetooth 7

8. NETWORK LAYER
Robust and High performance network infrastructure
Supports the communication requirements for latency,
bandwidth or security
Allows multiple organizations to share and use the same
network independently
Encryption,signal processing,LTE,Wifi,Sim Module,GSM,Micro
controller,Embedded-os etc…are used in network layer.

9. SERVICE LAYER
Also termed as Application service Layer.
 Capturing of periodic sensory data .
Data Analytics (Extracts relevant information from massive amount
of raw data).
Streaming Analytics (Process real time data).
 Ensures security and privacy of data.

10.  Lowest Abstraction Layer.
 With sensors we are creating digital nervous system.
 Incorporated to measure physical quantities.
 Interconnects the physical and digital world.
 Collects and process the real time information.
Transportation,Health care,Tracing people,Climatic conditions.etc
comes under application layer.

15. SENSORS EVEN IN THE 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 peryear.

16. SECURITY IN IOT
 Software can behackable.
 Connection isexposed.
 it is vulnerable, exposed, can be tapped.
 Weapons of mass disruption.

17. CONCLUSION
One certainty is that Internet of Things change our lifestyles, It is for
common good, The need is the input and support of technologists and
ordinary people to make it good for individuals and the society.
