The Internet of Things (IoT)
o Conceptualized in the early 2000’s, at MIT’s Auto-ID lab by Kevin Aston
“If we had computers that knew everything there was to know about things—using data they gathered
without any help from us -- we would be able to track and count everything, and greatly reduce waste,
loss and cost” - Kevin Aston in 1999
o “The Internet of Things is a system where items in the physical world, and sensors within or
attached to these items, are connected to the Internet via wireless or wired Internet
connections”.
IoT – Network of Networks
• Loose collection of disparate, purpose-built networks
• Building
• Heating system
• Venting system
• Lighting
• Telephony
• Car
• Engine control
• Dashboard
• Air-Bags
• Communication System
The Moore’s Law
 “The number of transistors in a dense integrated circuit doubles approximately every two
years”
 Also applicable to the size of the internet.
 Researchers have predicted that the size of the Internet will double, every 5.32 years.
 Size of the Internet is measured by the number of Autonomous Systems (Nodes)
 Proposed by a research group in China
 Results based on the data obtained in six-month intervals, (2001 to 2006)
IoT according to Cisco-IBSG
IoT is simply the point in time when
more “things or objects” were
connected to the Internet than
people.
IoT according to Cisco-IBSG
Considering the fraction of the
world’s population that is
actually connected to the
Internet.
IoT is simply the point in time when
more “things or objects” were
connected to the Internet than
people.
The IoT Stack - Architectural Reference
Model
The “Things” or devices are classified as:
o Non-electrical objects
 Food and Cargo, Animals, Trees, etc.
o Electrical devices that inherently lack sophisticated electronics
 Lighting, Heating, Water distribution system etc.
o Devices with electronics built into them, to fulfil their primary function
 Cars, Bikes, PDAs, Mobiles, etc.
o Environment sensors
 Moisture, Pollution, Temperature, etc.
Almost all of these devices are coupled with actuators and/or sensors.
Connecting the Devices

Power
IEEE 802.15.4 900 MHz,
2.4 GHz
250 Kbps 10 to 300m Very Low

Wi-Fi 2.4, 5 GHz 100 Mbps 10 to 100m High
GSM 900 MHz 270 Kbps 35 Km High
Virtualizing the Objects
o Recreating the functionality of real-world objects at the Machine level
o Ease of reusability, if it possesses well defined representation
o Better abstraction achieved, decreases the development time
o Improved modularity
Middleware
o A software infrastructure that glues together the networking hardware,
operating system, network stacks and applications. It sits between the
underlying protocols and the application layer.
o Effective control and management of objects
o Convert the data from lower layers to provide the appropriate
information to the application layer.
Application Layer
o Connect a device to the server
o Record and read the generated data
o Link the data to an application
o Cloud based design
IoT in Action-Dubai
The IoT concept is used to safeguard a network of 37 cranes and 5,000 workers near the world’s tallest
buildings in Dubai. Cranes that swing too close to one another are halted by an Internet-connected system.
IoT and the Mining Industry
Dundee Precious Metals a Canadian-
based, international mining
company utilizes WiFi-enabled
vehicles, haulers and crushers and
above-ground command centers to
capture real-time data, resulting in a
cost-savings of $2.5 million and
production increase of 400%.
IoT in Healthcare and Wearable
Electronics
Wearable devices to help track health
data.
Communicate with doctors and other
healthcare professionals directly.
A Band-Aid that indicates if a wound is
healed, skin patch wireless blood
glucose monitors and systems that
sound an alert when it’s time to refill a
prescription. All possible because of IoT
IoT and Law Enforcement
The Los Angeles police department
project uses data analytics to more
rapidly spot crime in progress, via
license plate readers on police cars.
These readers, which are in use as
officers conduct normal business,
digitally scan tens of thousands of
vehicles over the course of a single
day. This means automatic
notification of stolen vehicles to
officers as they drive past on their
routine patrol.
