1-1INTRODUCTION TO INTERNET OF THINGS (IoT)
INTERNET OF THINGS (IoT) AND ARTIFICIAL INTELLIGENCE (AI)
1.1. INTRODUCTION TO INTERNET OF THINGS (IoT)
The Internet helped people to connect with static information available but now it is helping to build
connection from people to people, people to physical objects and physical objects to other physical objects.
The speedy growth of Internet data is making networked connections more relevant and valuable. Also it
creates exciting business opportunities for industries. Almost all every area, every device, every sensor,
every software are connected to each other. The ability to access these devices through a Smartphone or
through a computer is called IoT (Internet of Things). These devices are accessed remotely. The Internet
of things (IoT) is one of the top three technological advancements of the next decade together with the
mobile, internet and the automation of knowledge work.
The idea is that not only your computer and your Smartphone can talk to each other, but also
all the things around you. From connected homes and cities to connected cars and machines
to devices that track an individual's behavior and use the data collected for new kind of services.
IoT is basically a platform where we connect everyday things
embedded with electronics, software, and sensors to the internet
enabling them to collect and exchange data. In this way, each of
your devices will learning from the experiences of other devices
just as humans do. The consumer products, durable goods, cars and
trucks, industrial and utility components, sensors, and other everyday
objects are being combined with Internet connectivity and powerful
data analytic capabilities that promise to transform the way we work
live and play as shown in Fig. 1.1.

KEY TERMS . . . . .
l Computer Network. A computer
network is a group of computers
linked to each other that enables the
computer to communicate with
another computer and share their
resources, data, and appli-cations.
l Internet. The Internet is a massive
network of networks, a networking
infrastructure. It connects millions of
computers together globally, forming
a network in which any computer can
communicate with any other
computer as long as they are both
connected to the Internet

1-2 INTRODUCTION TO INTERNET OF THINGS (IOT)
For example a user has a camera installed in his house he might
want to check the video recordings and all the feeds through a web
server. Another example if a user detects some changes in the
refrigerator the user can remotely adjust the temperature via their
phone.
1.1.1 Definition of IoT
Internet of Things is a new revolution of the Internet. Objects make
themselves recognizable and they obtain intelligence by making or
enabling context related decisions thanks to the fact that they can
communicate information about themselves. They can access
information that has been aggregated by other things, or they can be
components of complex services. There is however no single
universal definition.
IoT is a network of physical objects. The internet is not only a network of computers but it has evolved
into a network of device of all type and sizes. They are vehicles, smart phones, home appliances, toys,
cameras, medical instruments and industrial systems, animals, people and buildings. They all are connected,
communicating and sharing information based on stipulated
protocols in order to achieve smart reorganizations, positioning,
tracing, safe and control and even personal real time online
monitoring , online upgrade, process control and administration.
We can define Internet of things is an internet of three things as
shown in Fig.1.2: (a). People to people, (b) People to machine or
things, (c) Things or machine to things or machine, Interacting
through internet."
Fig.1.2. IoT Internet of Three Things
‘‘The Internet of Things (IoT) can be defined as a network of physical objects called ‘‘things’’
that are embedded with software, electronics, network and sensors which allows these objects
to collect and exchange data without any human intervention.’’
KEY POINTS . . . . .
What are the requirements for IoT
Networks?
l The capacity to connect a large
number of heterogeneous elements
l High reliability
l Real-time data transmission with
minimum delays
l The ability to protect all data flows
l The ability to configure applications
l Monitoring and traffic management at
the device level
l Cost-effectiveness for a large number
of connected objects
KEY TERMS . . . . .
Where is IoT used?
l The Internet of things (IoT) is the inter-
networking of physical devices,
vehicles, smart-devices, building, and
other items embedded with
electronics, software, sensors,
actuators, and network connectivity
which enable these objects to collect
and exchange data.
What is Physical Object?
l Physical objects are the ‘‘things’’ that
are embedded with software,
electronics, network and sensors
which allow these objects to collect
and exchange data without any
human intervention.
What is automation and control?
l Automation or automatic control is
the use of various control systems for
operating equipment such as
machinery, processes in factories,
boilers and heat treating ovens,
switching on telephone networks,
steering and stabilization of ships,
aircraft and other applications and
vehicles with minimal or reduced
human.

‘‘Sensors and actuators embedded in physical objects are linked through wired and wireless
networks, often using the same Internet Protocol (IP) that connects the Internet’’
– McKinsey
IoT is an advanced automation and analytics system which exploits networking, sensing, big
data, and artificial intelligence technology to deliver complete systems for a product or service.
These systems allow greater transparency, control and performance when applied to any
industry or system.
IoT is defined as a system of interrelated Physical Objects, Sensors,Actuators, Virtual Objects,
People, Services, Platforms, and Networks that have separate identifiers and an ability to
transfer data independently.
The goal of the Internet of Things is to enable things to be connected anytime, anyplace, with anything and
anyone ideally using any path/network and any service as shown in Fig. 1.3.
Fig.1.3. IoT Anytime, Anyplace, with Anything
The Internet of things will involve a massive build-out of connected
devices and sensors woven into the fabric of our lives and businesses.
Devices deeply embedded in public and private places will recognize
us and adapt to our requirements for comfort, safety, streamlined
commerce, entertainment, education, resource conservation,
operational efficiency and personal well-being. IoT systems have
applications across industries through their unique flexibility and
ability to be suitable in any environment. They enhance data
collection, automation, operations, and much more through smart
devices and powerful enabling technology.
IoT devices can range from simple to
complex. Here are some examples of IoT
devices which will be used within this
book:
l A smart door is an electronic door
which can be sent commands to be
locked or unlocked remotely. It can
also report on its current state (OPEN,
CLOSED or LOCKED),
l A Bell can be sent a command to
activate and ring for a short period.
l A Motion Sensor can be queried to
return the number of people who
have passed by since it was last reset.
l A Smart Lamp can be switched on or
off remotely. It can also report on its
current state (ON or OFF). When
switched on, a Motion Sensor within
the device checks to see if light is
needed and will dim if no-one is
nearby. Furthermore the device can
be report on the current luminosity
of the bulb.
As you can see, the Bell is an example
of a pure actuator, as it only reacts to
the given commands. Meanwhile the
Motion Sensor is an example of a pure
sensor, since it will only report on the
state of the world as it sees it. The
other two devices are able to both
respond to commands and report on
state in a meaningful way.

1.1.2. History of IoT
The term Internet of Things is 20 years old. But the actual idea of connected devices had been around
longer at least since the 1970s. Back then the idea was often called embedded internet. But the actual term
Internet of Things was coined by Kevin Ashton in 1999 during his work at Procter & Gamble.
1970 - The actual idea of connected devices was proposed.
1990 - John Romkey created a toaster which could be turned on/off over the Internet.
1995 - Siemens introduced the first cellular module built for M2M.
1999 - The term Internet of Things was used by Kevin Ashton during his work at P&G which became
widely accepted.Ashton who was working in supply chain optimization, wanted to attract senior
management's attention to a new exciting technology called RFID. Because the internet was the
hottest new trend in 1999 and because it somehow made sense, he called his presentation Internet
of Things.
2004 - The term was mentioned in famous publications like the Guardian, Boston Globe, and Scientific
American.
2005 - UN’s International Telecommunications Union (ITU) published its first report on this topic.
2008 - The Internet of Things was born.
2010 - The concept of IoT started to gain some popularity in the summer of 2010. Information leaked
that Google's StreetView service had not only made 360 degree pictures but had also stored tons
of data of people's Wifi networks. People were debating whether this was the start of a new
Google approach to not only index the internet but also index the physical world.
2011 - Gartner the market research company includes TheInternet ofThings technologyin their research.
2014 - The term Internet of Things reached mass market awareness when in January 2014 Google
announced to buy Nest. At the same time the Consumer Electronics Show (CES) in Las Vegas
was held under the theme of IoT.
1.2 CHARACTERISTICS OF IOT
The most important features of IoT include artificial intelligence, connectivity, sensors, active engagement,
and small device use as shown in Fig.1.4.
Fig.1.4. IoT Features

1. Artificial Intelligence. The AI - IoT technically makes things
smart, meaning that it enhances different aspects of life through
proper usage of that data, networks, and algorithms. This can range
from something as simple as improving or enhancing your
refrigerator by embedding it with sensors that automatically detect
when milk and eggs run low and to then place an order with your
choice of the grocer to automatically send them over. For companies
to realize the full potential of IoT enablement they need to combine
IoT with rapidly advancingArtificial Intelligence (#AI) technologies
as shown in Fig.1.5, which enable smart machines to simulate
intelligent behavior and make well informed decisions with little or
no human intervention.
Fig.1.5. AI and IoT
2. Connectivity. It is new enabling technologies for networking and specifically IoT networking, mean
networks are no longer exclusively tied to major providers. Networks can exist on a much smaller and
cheaper scale while still being practical. IoT creates these small networks between its system devices.
3. Sensors. The true essence of IoT would not hold effective or true without sensors. IoT would not be
possible without sensors which will detect or measure any changes in the environment to generate data
that can report on their status or even interact with the environment. The Fig.1.6 shown some types of
sensor used in IoT. Sensing technologies provide the means to create capabilities that reflect a true awareness
of the physical world and the people in it. The sensing information is simply the analogue input from the
physical world but it can provide the rich understanding of our complex world.
KEY TERMS . . . . .
Artificial Intelligence. Artificial
intelligence (AI) is an area of computer
science that emphasizes the creation of
intelligent machines that work and reacts
like humans. Some of the activities
computers with artificial intelligence are
designed for include:
l Speech recognition
l Learning
l Planning
l Problem solving
Sensor. A sensor is a device that detects
and responds to some type of input from
the physical environment. The specific
input could be light, heat, motion,
moisture, pressure, or any one of a great
number of other environmental
phenomena. The output is generally a
signal that is converted to human-readable
display at the sensor location or
transmitted electronically over a network
for reading or further processing.

Fig. 1.6. Types of Sensor
4. Active engagement. Today's interaction between different connected technologies happens through
passive engagement. IoT introduces a new paradigm for active content, product or service engagement.
5. Devices. Devices are more powerful, cheaper and smaller over time Internet ofThings purposely makes
use of small devices to deliver its scalability, versatility, and accuracy. Internet of Things (IoT) devices
support the expansion of internet connection beyond the usual standard devices like computers, laptops,
smartphones etc. These IoT devices are purely integrated with high definition technology which makes it
possible for them to communicate or interact over the internet smoothly and can also be managed and
controlled remotely when required. There are several advantages of these smart devices and some of them
are given below.
(a) IoT encourages the interaction between devices called as a machine to machine interaction.
(b) It provides good automation and control.
(c) Integrated with more technical information so it is better to operate.
(d) IoT possesses strong monitoring feature.
(e) It saves a lot of time.
(f) IoT helps to save more money by reducing manual task and time.
(g) Automating daily life tasks makes good monitoring of devices.
(h) Increased efficiency and time-saving.
(i) With good features make a better quality of life.
1.2.1 Some other Features
A brief review of these features is given below:
1. Dynamic changes. The state of devices change dynamically, e.g., sleeping and waking up, connected
and disconnected as well as the context of devices including location and speed. Moreover the number of
devices can change dynamically.
2. Heterogeneity. Heterogeneity in Internet of Things as one of the key characteristics. Devices in IoT are

based on different hardware platforms and networks and can interact with other devices or service platforms
through different networks. IoT architecture should support direct network connectivity between
heterogeneous networks. They can interact with other devices or service platforms through different
networks.
3. Self-adapting. IoT devices and systems may have the capability to dynamically adapt with the changing
contexts and take actions based on their operating conditions, user's context or sensed environment. For
example, consider a surveillance system comprising of a number of surveillance cameras. The surveillance
cameras can adapt their modes based on whether it is day or night. Cameras could switch from lower
resolution to higher resolution modes when any motion is detected and alert nearby cameras to do the
same. In this example, the surveillance system is adapting itself based on the context and changing (e.g.,
dynamic) conditions.
4. Security. IoT devices are naturally vulnerable to security threats. As we gain efficiencies and other
benefits from the IoT, it would be a mistake to forget about security concerns associated with it. There is
a high level of transparency and privacy issues with IoT. It is important to secure the endpoints, the
networks and the data that is transferred across all of it means creating a security paradigm.
5. Enormous scale. The number of devices that need to be managed
and that communicate with each other will be at least an order of
magnitude larger than the devices connected to the current Internet.
Even more critical will be the management of the data generated
and their interpretation for application purposes. This relates to
semantics of data as well as efficient data handling.
6. Integrated into information network. IoT devices are usually
integrated into the information network that allows them to
communicate and exchange data with other devices and systems.
The devices can be dynamically discovered in the network by other
devices and the network and have the capability to describe
themselves and their characteristics.
7. Unique identity. Each IoT device has a unique identity and a
unique identifier such as an IP address or a URL. IoT systems may
have intelligent interfaces which adapt based on the context; allow
communicating with users and the environmental contexts. IoT
device interfaces allow users to query the devices, monitor their
status, and control them remotely, in association with the control,
configuration and management infrastructure.
1.2.2. Challenges of IoT
IoT is a universe of connected things providing key physical data and further processing of that data in the
cloud to deliver business insights. They present a huge opportunity for many players in all businesses and
industries. Many companies are organizing themselves to focus on IoT and the connectivity of their future
products and services. For the IoT industry to flourish there are five categories of challenges to overcome
and this is true for any new trend in technology not only IoT: technology, business, society, privacy and
standard.
1. Technology. This part is covering all technologies needed to make IoT systems function smoothly as a
standalone solution or part of existing systems and that's not an easy mission. As Fig 1.7 shown there are
many technological challenges, including security, connectivity, compatibility and longevity, standards
What is the scope of IoT?
"Internet of Things can connect devices
embedded in various systems to the
internet. When devices/objects can
represent themselves digitally, they can be
controlled from anywhere. The
connectivity then helps us capture more
data from more places, ensuring more
ways of increasing efficiency.
Why IoT ?
l Universal inter-networking
l Acts as technology integrator. Flexible
configuration.
l Integrating human society and
physical systems.
l Improves the resource utilization ratio.
l Dynamic control of industry and daily
life.

and intelligent analysis and actions.
Fig.1.7. Technological Challenges
(a) Security. IoT has already turned into a serious security concern that has drawn the attention of firms
and government agencies across the world. The hacking of baby monitors, smart fridges, thermostats,
drug infusion pumps, cameras and even the radio in your car are signifying a security nightmare being
caused by the future of IoT.
(b) Connectivity. Connecting so many devices will be one of the
biggest challenges of the future of IoT. It will defy the very structure
of current communication models and the underlying technologies.
At present we rely on the centralized, server/client paradigm to
authenticate, authorize and connect different nodes in a network.
(c) Compatibility and Longevity. IoT is growing in many different
directions, with many different technologies competing to become
the standard. This will cause difficulties and require the deployment
of extra hardware and software when connecting devices.
(d) Standards. Technology standards which include network
protocols, communication protocols, and data-aggregation standards,
are the sum of all activities of handling, processing and storing the
data collected from the sensors. This aggregation increases the value
of data by increasing, the scale, scope, and frequency of data
available for analysis.
(e) Intelligent analysis and actions. The last stage in IoT
implementation is extracting insights from data for analysis. The
analysis is driven by cognitive technologies and the accompanying
models that facilitate the use of cognitive technologies.
2. Business. The bottom line is a big motivation for starting, investing and operating any business, without
a sound and solid business model for IoT. This model must satisfy all the requirements for all kinds of e-
commerce vertical markets, horizontal markets, and consumer markets. But this category is always a
victim of regulatory and legal scrutiny. IoT can be divided into 3 categories, based on usage and clients
base as shown in Fig.1.8.
(a) Consumer IoT. It includes the connected devices such as smart cars, phones, watches, laptops, connected
appliances, and entertainment systems.
(b) Commercial IoT. It includes things like inventory controls, device trackers, and connected medical
devices.
(c) Industrial IoT. It covers such things as connected electric meters, waste water systems, flow gauges,
pipeline monitors, manufacturing robots, and other types of connected industrial devices and systems.
How does IoT help in our life?
l Along with advanced data analytics,
IoT-enabled devices and sensors are
helping us reduce air pollution in some
of our world's biggest cities, improve
agriculture and our food supply, and
even detect and contain deadly
viruses.
How are IoT devices connected?
l The IoT device will typically be
connected to an IP network to the
global Internet. Commercial IoT
where local communication is
typically either Bluetooth or Ethernet
(wired or wireless). The IoT device will
typically communicate only with local
devices
How many IoT devices will there be in
2020?
l The number of IoT devices that are
active is expected to grow to 10 billion
by 2020and 22 billion by 2025.

Fig. 1.8. Categories of IoT
So it is important to understand the value chain and business model for the IoT applications for each
category of IoT.
3. Society. Understanding IoT from the customers and regulators prospective is not an easy task for the
following reasons:
(a) Customer demands and requirements change constantly.
(b) New uses for devices as well as new devices and grow at breakneck speeds.
(c) Inventing and reintegrating must-have features and capabilities are expensive and take time and
resources.
(d) The uses for Internet of Things technology are expanding and changing-often in uncharted waters.
(e) Each of these problems could put a dent in consumers' desire to purchase connected products,
which would prevent the IoT from fulfilling its true potential.
(f) Lack of understanding or education by consumers of best practices for IoT devices security to help
in improving privacy, for example change default passwords of IoT devices.
4. Privacy. The IoT creates unique challenges to privacy, many that go beyond the data privacy issues that
currently exist. This is becoming more prevalent in consumer devices, such as tracking devices for phones
and cars as well as smart televisions. In terms of the latter, voice recognition or vision features are being
integrated that can continuously listen to conversations or watch for activity and selectively transmit that
data to a cloud service for processing, which sometimes includes a third party. The collection of this
information exposes legal and regulatory challenges facing data protection and privacy law.
5. Regulatory standards. Regulatory standards for data markets are missing especially for data brokers.
They are companies that sell data collected from various sources. Even though data appear to be the
currency of the IoT, there is a lack of transparency about who gets access to data and how those data are
used to develop products or services and sold to advertisers and third parties. There is a need for clear
guidelines on the retention, use and security of the data including metadata.
1.2.3. Advantages of IoT
The advantages of IoT span across every area of lifestyle and business. The key benefits of IoT technology
are as follows:
1. Technical optimization. IoT technology helps a lot in improving technologies and making them better.
For example with IoT a manufacturer is able to collect data from various car sensors. The manufacturer
analyzes them to improve its design and make them more efficient.
2. Data. The more the information, the easier it is to make the right decision. Knowing what to get from

the grocery while you are out, without having to check on your own,
not only saves time but is convenient as well.
3. Improved data collection. Traditional data collection has its
limitations and its design for passive use. IoT facilitates immediate
action on data.
4. Reduced waste. IoT offers real-time information leading to
effective decision making & management ofresources. For example,
if a manufacturer finds an issue in multiple car engines, he can track
the manufacturing plan of those engines and solves this issue with
the manufacturing belt.
5. Tracking. The computers keep a track both on the quality and
the feasibility of things at home. Knowing the expiration date of
products before one consumes them improves safety and quality of
life.Also, you will never run out of anything when you need it at the
last moment.
6. Improved customer engagement. IoT allows you to improve
customer experience by detecting problems and improving the
process.
7. Money. The financialaspect is the best advantage.This technology
could replace humans who are in charge of monitoring and
maintaining supplies.
1.2.4. Disadvantages IoT
1. Security. IoT technology creates an ecosystem of connected devices. However, during this process, the
system may offer little authentication control despite sufficient security measures.
2. Privacy. The use of IoT, exposes a substantial amount of personal data, in extreme detail, without the
user's active participation. This creates lots of privacy issues.
3. Flexibility. There is a huge concern regarding the flexibility of an IoT system. It is mainly regarding
integrating with another system as there are many diverse systems involved in the process.
4. Complexity. The design of the IOT system is also quite complicated. Moreover, it's deployment and
maintenance also not very easy. There are several opportunities for failure with complex systems. For
example, both you and your spouse may receive messages that the milk is over and both of you may end
up buying the same. That leaves you with double the quantity required. Or there is a software bug causing
the printer to order ink multiple times when it requires a single cartridge.
5. Compliance. IOT has its own set of rules and regulations. However, because of its complexity, the task
of compliance is quite challenging.
6. Safety. There is a chance that the software can be hacked and your personal information misused. The
possibilities are endless. Your prescription being changed or your account details being hacked could put
you at risk. Hence, all the safety risks become the consumer's responsibility.
1.2.5. How IoT works?
The entire IoT process starts with the devices themselves like smartphones, smartwatches, electronic
machine like TV, Washing Machine which helps you to communicate with the IOT platform as shown in
Fig.1.9. Here, are four fundamental components of an IoT system:
What is the future of IoT?
l IoT devices will be a huge part of how
we interact with basic everyday
objects. In just one year alone, we
went from having 5 million IoT devices
connected to the internet to billions.
The future is happening now, and
these devices are getting smarter
every day through machine learning
and artificial intelligence.
Does IoT always need Internet?
l The network supports a range IoT
applications suited to devices in
motion or remote locations, or that
must be secure before connection to
the cloud. Because USSD is feature
in all cellular networks, it can provide
secure IoT connectivity without
involving the Internet.
Are IoT devices secured?
l When your individual devices are
secure, the main point of entry into
your IoT is going to be through your
main network. . It is likely that your
computer's operating system (OS) has
some sort of firewall software, but this
won't protect the other devices on
your network.

Fig.1.9 How IoT Works
1. Sensors/Devices. Sensors or devices are a key component that helps you to collect live data from the
surrounding environment. All this data may have various levels of complexities. It could be a simple
temperature monitoring sensor or it may be in the form of the video feed.
A device may have various types of sensors which performs multiple tasks apart from sensing. Example,
A mobile phone is a device which has multiple sensors like GPS, camera but your smartphone is not able
to sense these things.
2. Connectivity : All the collected data is sent to a cloud infrastructure. The sensors should be connected
to the cloud using various mediums of communications. These communication mediums include mobile
or satellite networks, Bluetooth, WI-FI, WAN, etc.
3. Data Processing : Once that data is collected, and it gets to the
cloud, the software performs processing on the gathered data. This
process can be just checking the temperature, reading on devices
likeAC or heaters. However, it can sometimes also be very complex
like identifying objects, using computer vision on video.
4. User Interface : The information needs to be available to the
end-user in some way which can be achieved by triggering alarms
on their phones or sending them notification through email or text
message. The user sometimes might need an interface which actively
checks their IOT system. For example, the user has a camera installed
in his home. He wants to access video recording and all the feeds
with the help of a web server.
However, it's not always one-way communication. Depending on
the IoT application and complexity of the system, the user may also
be able to perform an action which may create cascading effects.
For example, if a user detects any changes in the temperature of the
refrigerator, with the help of IOT technology the user should able to
adjust the temperature with the help of their mobile phone.
1.3. APPLICATIONS OF IOT
To the public IoT currently appears to be a mixture of smart home applications, wearables and an industrial
IoT component. But actually it has the potential to have a much wider reach. When the connected world
becomes reality, the Internet of Things will transform nearly all major segments - from homes to hospitals
and from cars to cities. IoT has many applications, but we will cover top IoT Applications with uses as
shown in Fig.1.10.
How do I protect my IoT devices?
Here are some precautions you should
take to protect your IoT devices.
l Set passwords. Not many people
know they can set passwords for IoT
devices, making their gadgets easy to
hack.
l Disable Universal Plug and Play
(UPnP) .
l Create a separate network. .

the behaviors of electricity suppliers and consumers in an automated
fashion to improve the efficiency, reliability and economics of
electricity.
Fig. 1.14. Smart grids -IoT Applications
What do smart grids do?
l The grid refers to the electric grid, a
network of transmission lines,
substations, transformers and more
that deliver electricity from the power
plant to your home or business. It's
what you plug into when you flip on
your light switch or power up your
computer.
Why smart grid is important?
l A smart grid can help utilities conserve
energy, reduce costs, increase
reliability and transparency, and make
processes more efficient. The
increasing use of IT-based electric
power systems, however, increases
cyber security vulnerabilities, which
increases cyber security's importance.
What is two way communications in
smart grid?

1.3.5. IoT ? Industrial Internet Applications
One wayto think of the Industrial Internet is, as connecting machines
and devices in industries such as power generation, oil, gas, and
healthcare. It is also made use of in situations where unplanned
downtime and system failures can result in life-threatening situations.
A system embedded with the IoT tends to include devices such as
fitness bands for heart monitoring or smart home appliances. These
systems are functional and can very well provide ease of use but are
not reliable because they do not typicallycreate emergency situations
if a downtime was to occur.
1.3.6. IoT ? Connected Health (Digital Health)
Applications
The connected car technology is a vast and an extensive network of
multiple sensors, antennas, embedded software and technologies
that assist in communication to navigate in our complex world (as
shown in Fig.1.15). It has the responsibility of making decisions
with consistency, accuracy and speed. It also has to be reliable. The
battle is on for the car of the future. Whether it is self-driving or just
driver-assisted: Connectivity with other cars, mapping services, or
traffic control will play a part. Next generation in-car entertainment
systems and remote monitoring are also interesting concepts to watch
as shown in 1.15 and it is not only large auto-makers that play a
role: Google, Microsoft, and Apple have all announced connected
car platforms.

Are self driving cars IoT?
l The concept of self-driving cars has
always intrigued many people. These
autonomous vehicles require an
enormous quantity of data collecting
and processing. In this case, through
IoT, the driverless car shares
information about the road (which has
already been mapped out).
What do self driving cars do?
l Self-driving vehicles are cars or trucks
in which human drivers are never
required to take control to safely
operate the vehicle. Also known as
autonomous or "driverless" cars, they
combine sensors and software to
control, navigate, and drive the
vehicle.
How do driverless cars help the
environment?
l Yes, most of the driverless vehicles
being driven (and test-driven) today
are already fully electric. ...
Autonomous cars use significantly less
gas and energy when driving,
compared to a vehicle driven by a
human. Most gas is burned when
driving at high speeds, braking, and
re-accelerating excessively.

to most organizations and individuals. The energy sources for massive IoT applications are shown in
Fig. 1.18.
Fig.1.18 Energy sources for IoT Applications
1. Residential Energy. The rise of technology has driven energy
costs up. Consumers search for ways to reduce or control
consumption. IoT offers a sophisticated way to analyze and optimize
use not only at device level, but throughout the entire system of the
home. This can mean simple switching off or dimming of lights, or
changing device settings and modifying multiple home settings to
optimize energyuse. IoT can also discover problematic consumption
from issues like older appliances, damaged appliances, or faulty
system components. Traditionally, finding such problems required
the use of often multiple professionals.
2. Commercial Energy. Energy waste can easily and quietly impact business in a major way, given the
tremendous energy needs of even small organizations. Smaller organizations wrestle with balancing costs
of business while delivering a product with typically smaller margins, and working with limited funding
and technology. Larger organizations must monitor a massive, complex ecosystem of energy use that
offers few simple, effective solutions for energy use management.
1.3.10. IoT - Transportation Application
At every layer of transportation, IoT provides improved communication, control, and data distribution.
These applications include personal vehicles, commercial vehicles, trains, UAVs, and other equipment. It
extends throughout the entire system of all transportation elements such as traffic control, parking, fuel
consumption, and more.
The number one concerns of traffic is handling congestion, decreasing accidents, and parking. IoT allows
us to better take a look at and analyze the go with the flow of visitors through gadgets in any respect traffic
commentary factors. It aids in parking with the aid of making storage glide obvious whilst present-day
techniques offer little if any statistics. Accidents usually end result from more than a few of factors, but,
visitors' management impacts their frequency. Production sites, poor rerouting, and a lack of facts about
traffic reputation are all issues that result in incidents. IoT provides solutions within the shape of higher
What is Smart Energy in IoT?

educators to give focus to individuals and their method. It also
reduces costs and labor of education through automation of common
tasks outside ofthe actual education process. Some of IoT -education
applications are:
1. Education Organizations. Education organizations typically
suffer from limited funding, labor issues, and poor attention to actual
education. They, unlike other organizations, commonly lack or avoid
analytics due to their funding issues and the belief that analytics do
not apply to their industry. IoT not only provides valuable insight,
but it also democratizes that information through low-cost, low-
power small devices, which still offer high performance. This
technology aids in managing costs, improving the quality of
education, professional development, and facility management

(c) Facility monitoring and maintenance
(d) Data from other facilities
(e) Educators
2. Educators. IoT provides instructors with easy access to powerful educational tools. Educators can use
IoT to perform as a one-on-one instructor providing specific instructional designs for each pupil; for
example, using data to determine the most effective supplements for each student, and auto generating
content from lesson materials on-demand for any student.
3. Personalized education. IoT facilitates the customization of education to give every student access to
what they need. Each student can control their experience and participate in instructional design, and
much of this happens passively. The student simply utilizes the system, and performance data primarily
shapes their design. This combined with organizational and educator optimization delivers highly effective
education while reducing costs.
1.3.12. IoT ? Government Applications
IoT supports the development of smart nations and smart cities. This includes enhancement of infrastructure
previously discussed (e.g., healthcare, energy, transportation, etc.), defense and also the engineering and
maintenance of communities. Some of government application are:
