2. What is IoT?
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.
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 economic benefit.
• Internet of Things is a system of interrelated computing devices or objects
which have the ability to transfer the data over a network without
requiring any human to human or human to computer interaction uniquely
addressable, based on standard communication protocol.

3. "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.

4. • We can turn almost every object into a “thing”.
• A “thing” still looks much like an embedded system currently.
• A “thing” generally consists of four main parts:
– Sensors & actuators
– Microcontroller
– Communication unit
– Power supply
• A “thing” has the following properties:
– It’s usually powered by battery. This implies limited source of energy.
– It’s generally small in size and low in cost. This limits their computing
capability.
– It doesn’t usually perform complicated tasks.
• Power consumption is the main design issue.

7. Reasons of IoT
• Data deluge : The explosion of the amount of data collected and
exchanged is one of the major reason why IoT came in
existence. Forecasts indicate that in the year 2025 more than
900 Exabytes of data are stored. So we need novel mechanisms
to find, fetch, and transmit data.
• There is decrease in energy required to operate intelligent
devices. The search will be for a zero level of entropy where
the device or system will have to harvest its own energy.
• Miniaturization of devices: the devices are becoming
increasingly smaller.
• Autonomic management: the devices/systems of future will
have self-management, self-healing, and self-configuration
capabilities.
• IPv6 as an integration layer: allows to exploit the potential of
IPv6 and related standards.

8. • Sensors:
–They are mainly input components
–They sense and collect surrounding information
–Basically three types:
• Passive, omnidirectional (e.g. mic)
• Passive, narrow-beam sensor
• Active sensors (e.g. sonar, radar, etc.)
• Actuators:
–They are mainly output components
–They alter the surrounding.
–Some examples:
• Adding lighting, heat, sound, etc.
• Controlling motors to move objects
• Displaying messages
• and others…

9. • A “thing” always feature communications for “team working”
• The Role of Communications
– Providing a data link between two nodes
• Communication type:
– Wireline (e.g. copper wires, optical fibers)
–Wireless (e.g. RF, IR). RF-based
communication is the most popular choice (and
also our focus)
• Popular RF-based communication solutions:
– IEEE 802.15.4
–IEEE 802.11 (or Wi-Fi)
–Bluetooth
–Near Field Communication (NFC), e.g. RFIDa
Communications

10. • The Roles of Networks
– Managing nodes (discovery, join, leave, etc).
– Relaying data packets from the source to the destination node in the
network.
• Networks are a distributed system. All nodes need to perform
networking related tasks.
• RF-based Network in IoT is usually a Wireless Multi-hop
Network.
– Wireless Sensor Networks
– Mobile Wireless Ad hoc Networks
– Wireless Mesh Networks
– Vehicular Ad Hoc Networks
– and many others...
• Main concern: Reliability & Performance

11. The Internet
• The Internet serves as a wide area networking for a local
network.
• The Internet uses TCP/IP. This implies that things must also
support TCP/IP.
• Gateway (or sink)

12. 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

14. 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 control.

31. Sensors in even 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 per year. 31

37. Of course, we know nothing remains static, especially
when it comes to the Internet. Initiatives and advances,
such as Cisco‘s Planetary Skin, GE’s Industrial Internet,
HP‘s central nervous system for the earth (CeNSE), and
smart dust, have the potential to add millions—even
billions—of sensors to the Internet.
As cows, water pipes, people, and even shoes, trees,
and animals become connected to IoT, the world has the
potential to become a better place.
“With a trillion sensors embedded in the
environment—all connected by computing systems,
software, and services—it will be possible to hear the
heartbeat of the Earth, impacting human interaction with
the globe as profoundly as the Internet has revolutionized
communication.” - Peter Hartwell, Senior Researcher, HP
Labs.
“How much more IoT can do is only left to your
imagination”

38. Internet of Things is the next stage of the information
revolution and referenced the inter-connectivity of everything
from urban transport to medical devices to household
appliances.
Integration with the Internet implies that devices will use
an IP address as a unique identifier. However, due to the limited
address space of IPv4 (which allows for 4.3 billion unique
addresses), objects in the IoT will have to use IPv6 to
accommodate the extremely large address space required.
Objects in the IoT will not only be devices with sensory
capabilities, but also provide actuation capabilities (e.g., bulbs
or locks controlled over the Internet).
38

39. On the other hand, IoT systems could also be responsible
for performing actions, not just sensing things. Intelligent
shopping systems, for example, could monitor specific users'
purchasing habits in a store by tracking their specific mobile
phones. These users could then be provided with special offers
on their favourite products, or even location of items that they
need, which their fridge has automatically conveyed to the
phone.
