UNIT -1 The Internet of Things

Internet of Things refers to the concept of connecting a device to other devices through
the Internet. Such devices are capable of processing and are equipped with hardware
and software suitable to a specific purpose, which the device fulfills.

What is IoT?

An IoT ecosystem consists of electronic devices, users, and at the center, the
Internet. IoT aims to create interconnections of flexibly scalable sizes. In an IoT
network, there are a number of digital devices connected to the internet.

Each device would ideally serve a specific purpose of its own. To be able to use
internet access and perform various tasks, an IoT device is equipped with a microchip
for processing.

Why is Internet of Things (IoT) so Important?

With technological advancements, increasing internet users, and more devices being
evolved to more digital and responsive forms, IoT has greatly gained momentum. It has
become an important tool in reducing the gap between a device and the user.

• IoT has helped eliminate barriers such as linguistic differences, physical

disabilities, distant communication, etc.
• A.I. has become more accessible and portable than ever with the uprising of IoT
in the form of A.I. SoCs (system on chip) and connection to A.I. on the cloud.
• Devices become more responsive, featureful and interactive. An IoT based clock
for an instance does more than just showtime.
• IoT has enabled new advancements such as remote sensing, technological
medical equipment, satellite technology components, etc.
• IoT devices help in more effective and efficient data collection.

Technologies That Have Made IoT Possible

Following three technological advancements have made it possible for IoT to come this
far:

1. Increase in Processing Capability of Embedded Platforms

Microcontrollers have been replaced by general-purpose processors in computational

devices because of ever-reducing cost, power requirements, and size in exchange for
the same amount of processing potential.

This shift to modern CPUs is crucial because CPUs can run operating systems with
support for major programming languages and complete networking stacks, something
microcontrollers can not do.
 UNIT -1 The Internet of Things
2. Development of Small-footprint OSs and Protocols

With an increase in the performance of embedded platforms, the hardware demands

of lightweight operating systems either reduce or remain unaltered.

On the protocol side, such a dynamic occurred as lightweight TCP/IP stacks were
written for embedded platforms. And also new protocols were written keeping in mind
the limited processing bandwidth and capability of these devices.

3. Development of Wireless Communications

Choices in connectivity methods for low power and small devices have been increasing
in the consumer and industrial markets. Popular options include Xbee, Zigbee, cellular
communications, mesh networking, Bluetooth, WiFi, etc.

Wired network connections are not always feasible to be used with IoT devices.
Wireless network connections solve this problem.

How Does IoT Work?

An IoT network consists of devices that have built-in sensors. Such devices are
connected to a platform that stores data from them. The relevant data is then utilized
for performing tasks that fulfill the requirements of users.

Data is stored on the IoT platforms, but not all of it would be useful. IoT devices select
only certain data pieces that are significant to perform some task. These pieces of data
are able to identify patterns, make recommendations, predict problems beforehand.
Following are the four major components of an IoT ecosystem:

1. Sensors

sensors are embedded within the devices of an IoT network. A sensor obtains all the
details from an environment that can have many complexities. Sensors detect even the
most sensitive changes. this heavily improves security. These sensors collect all the
data. Ex, a smartphone can detect a user's location.

2. Connectivity

After being collected, data is sent to the cloud infrastructure. It is also called an IoT
platform. To transfer the data, the devices will need a medium. Connections like WAN,
Bluetooth, Wi-Fi, mobile networks, etc act as that medium. These media are different
from one another and provide varying results and security effects.
 UNIT -1 The Internet of Things
3. Data Processing

On the IoT platform (cloud infrastructure) the data is analyzed. This process of analysis
is one of the biggest obstacles in IoT application development. The analysis can be as
simple as checking the speed of a fan or as complicated as using hybrid AI/software
tech for identifying security intrusions using hardware such as infrared cameras. An IoT
application should be developed in a manner such that it can process all the data
efficiently and in real-time.

4. User Interface

In this step, the user is informed about the actions by making use of a notifier service or
an alert system to the IoT application. This way the user will be informed that their
commands have been executed in the systems.

• IoT has several applications in healthcare, such as remote monitoring
equipment, smart sensors, equipment integration.
• Retailers have begun adopting IoT products and services across a number of
applications that improve store operations.
• Through IoT physical retailers can compete against online challengers more
strongly. They can regain their lost market share and attract consumers into the
store, thus making it easier for them to buy more while saving money.
• Supply chains have been using IoT for some years now. IoT provides solutions to
issues such as tracking goods while they are in transit, helping suppliers
exchange inventory information, etc.

IoT Deployment

The initial planning does not have much to do with the technology of IoT. Rather, it is
much related to what the business aims to achieve. The next step after setting
business goals is to design a compliant network that will accomplish these goals.

A network design and specification must cover the schema of the network, the choice
of components, their locations and measurement of their performance.

As soon as wireless technology is added to any project, the project's complexity is also
increased. Not only must the correct system architecture be created, but also tackling
the other challenges such as signal strength, etc is required. Mobile-based IoT
deployments may also require a certification stage.

No deployment goes live without a fairly long period of intense testing. Technology is
not the only aspect of testing. It is vital to also do checks against the original business
goals.

After this, IoT deployment undergoes a digital transformation that improves efficiency,
reduces costs, increases revenue, etc.

Major Components of IoT

Things or Devices

The key physical items being tracked are Things or Devices. Smart sensors are
connected to things/devices which further continues to collect data from the device
and send it to the next layer, which is the portal or also called as the gateway Small
smart sensors for a variety of applications are now possible because of new
advancements in microelectronics.

Some commonly used sensors are:

• Temperature sensors and thermostats

• Pressure sensors
• Humidity / Moisture level
• Light intensity detectors
 UNIT -1 The Internet of Things
• Moisture sensors
• Proximity detection
• RFID tags

User Interface

User interface also termed as UI is nothing but a user-facing program that allows the
user to monitor and manipulate data.

The user interface (UI) is the visible, tangible portion of the IoT device that people can
interact with. Developers must provide a well-designed user interface that requires the
least amount of effort from users and promotes additional interactions.

Cloud

Cloud storage is used to store the data which has been collected from different
devices or things. Cloud computing is simply a set of connected servers that operate
continuously(24*7) over the Internet.

IoT devices, applications, and users generate massive amounts of data, which must be
managed efficiently. Data collection, processing, management, and archiving are
among the responsibilities of IoT clouds. The data can be accessed remotely by
industries and services, allowing them to take critical decisions at any time.

In the simplest terms, an IoT cloud is a network of servers optimized to handle data at
high speeds for a large number of different devices, manage traffic, and analyze data
with great accuracy. An IoT cloud would not be complete without a distributed
management database system.

Analytics

After receiving the data in the cloud, that data is processed. Data is analyzed here with
the help of various algorithms like machine learning and all.

Analytics is the conversion of analog information via connected sensors and devices
into actionable insights that can be processed, interpreted, and analyzed in depth.
Analysis of raw data or information for further processing is a prerequisite for the
monitoring and enhancement of the Internet of things (IoT).

Among the most significant benefits of a well-designed IoT system is real-time smart
analysis, which enables designers to spot anomalies in gathering information and
respond quickly to avoid an undesirable situation. If information is collected correctly
and at the right moment, network operators can plan for the next steps.
 UNIT -1 The Internet of Things
Network Interconnection

Over the past few years, the IoT has seen massive growth in devices controlled by the
internet and connected to it. Although IoT devices have a wide variety of uses, there are
some common things among them also along with the differences between them.

IoT is enabled by a variety of technologies. The network used to communicate with

other devices in an IoT deployment is critical to the field, a position that numerous
wireless or wired technologies can fill.

System Security

Security is a crucial component of IoT implementation, but this security point of view is
too often overlooked during the design process. Day after day weaknesses within IoT
are being attacked with evil intent – however, the majority of them that can be easily
and inexpensively addressed.

A secure network begins with the elimination of weaknesses within IoT devices as well
as the provision of tools to withstand, recognize, and recoup from harmful attacks.

Central Control Hardware

The two or more data flow among multiple channels and interfaces is managed by a
Control Panel. The additional duty of a control panel is to convert various wireless
interfaces and ensure that linked sensors and devices are accessible.

Example: Street light monitoring

Streetlights Are Quite An Important Part Of A City Because It Helps In Giving Better
Vision Of Roads And Streets At Night Time.

Machine to Machine (M2M)

Machine-to-machine (M2M) communication is the exchange of information between

machines. M2M is a network of physical objects capable of capturing information
about their state, communicating that information over a network without requiring
human interference, and using that information to control their operational behavior.

Characteristics of M2M (Machine-to-Machine)

• Focused Communication:

M2M is a subset of IoT that focuses on direct communication between machines

or devices, often for predefined tasks.

• Task-Specific:
 UNIT -1 The Internet of Things
M2M devices and communication are often task-specific, designed to perform a
particular function or monitor specific data points.

• Minimal Human Intervention:

M2M minimizes or eliminates the need for human intervention in device

communication, as it primarily involves automated interactions.

• Efficiency:

M2M is designed for efficiency, optimizing resource usage and automating

processes to achieve specific goals.

M2M Application: Industrial Manufacturing

In an M2M application within industrial manufacturing, machines on the factory floor

directly communicate with each other. For example, robotic arms, conveyor belts, and
quality control systems work together seamlessly. When a product reaches a
particular stage of production, sensors on machines can trigger automated actions,
such as shifting the product to the next station or performing quality checks. This
direct, machine-to-machine communication streamlines the manufacturing process,
enhancing effectiveness and reducing errors, with minimal human intervention.

Types of IoT

The networking, communication and connectivity protocols depend largely on the

specific IoT application deployed. Just as there are many different IoT devices, there
are many types of IoT applications based on their usage. Here are some of the most
common ones:

• Consumer IoT - Primarily for everyday use. Eg: home appliances, voice
assistance, and light fixtures.

• Commercial IoT - Primarily used in the healthcare and transport industries. Eg:
smart pacemakers and monitoring systems.
 UNIT -1 The Internet of Things
• Military Things (IoMT) - Primarily used for the application of IoT technologies in
the military field. Eg: surveillance robots and human-wearable biometrics for
combat.

• Industrial Internet of Things (IIoT) - Primarily used with industrial applications,

such as in the manufacturing and energy sectors. Eg: Digital control systems,
smart agriculture and industrial big data.

• Infrastructure IoT - Primarily used for connectivity in smart cities. Eg:

infrastructure sensors and management systems.
Examples of IOT:
1. Smart Home Security

Let's start with how IoT helps secure your home. Window and door contacts, glass
break and motion detectors, and heat, smoke, and water detectors combined with
security alarm pads, cameras, and smart doorbells help secure your home against
break-ins, fire, and floods.

Readings and alarms from these sensors flow to an in-home controller and then on to
the cloud via the Internet or through battery-powered cellular communicators.

From the cloud, you will be alerted through a mobile phone or computer app to any
untoward activity in the home. Using the app, you can check sensor logs and cameras
to determine what's happening and where. You can arm or disarm the security system
remotely to deny or allow access to your home. For more security, you can set up
personalized access codes for specific authorized users and be informed when they
enter and leave your home.

Forgot to arm your security system? With geofencing arming reminders, you'll be
notified if you go beyond a specified distance from your home. You can then use your
app to arm the system.

You could already open your front door using a keypad code, but now iris scanning,
voice recognition, and facial recognition may soon eliminate the need for keys or
codes.

2. Smart Home: Heating & Cooling

Programmable thermostats have long been able to detect and adjust temperatures
and humidity to suit individual preferences: daytime, nighttime, vacations, weekends,
et. Now with smart thermostats and sensors, a whole new set of capabilities is
available.
 UNIT -1 The Internet of Things
First, the system can be connected by Wi-Fi to the cloud and accessed and controlled
remotely through a mobile app. From a vacation spot, the car, or even from the couch
in front of their TV, users can monitor and adjust temperatures for their comfort. And
with smart sensors in your bathroom or workout room, the system can automatically
and individually adjust the temperature and humidity as you or another family member
shower or exercise.

If you live in an older home without central heating and air conditioning, you can still
get a smart room air conditioner. On your way home on a hot and sticky evening? Just
switch on the unit ahead of time through your cell phone app. Or tell Google Assistant
or Amazon Alexa to switch it on as you walk in the door.

Your heating and cooling system can be set up to send you an alarm if something is
detected outside of acceptable ranges. On a wintery day, you certainly want to know if
your heating is out before the water pipes freeze and burst! It gives you a chance to turn
off the water with your Smart Home app, or simply disarm your security system, so a
friend can get in to do it the old-fashioned way!

The heating system may also include gas, smoke, or CO2 sensors and check the air in
your home to determine if conditions are outside set parameters, alerting you (and your
alarm service) of possible gas leaks, fires, or water leaks.

3. Smart Home: Kitchen

One of the first commercially available IoT devices was the internet Digital DIOS smart
refrigerator announced by LG Electronics in 2000. Although that web-enabled model
was not deemed a success, it has been followed by smart IoT products from almost
every kitchen appliance manufacturer.

Today, in your kitchen you'll find Wi-Fi-enabled fridges, faucets, gas and electric
ranges, microwave ovens, coffee makers, pizza ovens, wine coolers, dishwashers, and
toasters. You'll also find Wi-Fi controlled washer and dryer in your laundry room and
even a smart toilet in your bathroom!

Smart refrigerators have a variety of features that you can control via mobile phone
app. Some features include cameras inside the fridge, so you can monitor what's
inside, and a touchscreen on which you can pull up recipes or create shopping lists.

Often, smart appliances are compatible with industry voice assistants, so you can ask
Siri, Alexa, or Google Assistant to dispense ice, turn on your oven, or add something to
your shopping list!.

Designing connected devices for the Internet of Things (IoT) involves considering
various principles to ensure functionality, security, scalability, and user
experience. Here are some key design principles for IoT devices:
 UNIT -1 The Internet of Things
1. Interoperability: Devices should be designed to communicate and interact
seamlessly with each other, regardless of manufacturer or technology. This often
involves adhering to common standards and protocols such as MQTT, CoAP, or
HTTP.
2. Scalability: IoT systems should be able to handle a large number of devices and
data streams efficiently as the network grows. Scalable architectures, both on
the device side and the cloud/backend side, are essential to accommodate
increasing numbers of users and devices.
3. Security: Security is paramount in IoT systems to protect against unauthorized
access, data breaches, and malicious attacks. Design considerations include
encryption, authentication mechanisms, secure boot, over-the-air (OTA)
updates, and secure data transmission protocols.
4. Reliability: IoT devices should be designed to operate reliably under various
conditions, including network disruptions, power outages, and harsh
environments. Redundancy, fault tolerance, and robust error handling
mechanisms are critical for ensuring continuous operation.
5. Low Power Consumption: Many IoT devices are battery-powered or have limited
power sources, so minimizing power consumption is essential to extend battery
life and reduce maintenance requirements. This involves optimizing hardware
design, software algorithms, and communication protocols for energy efficiency.
6. Data Privacy: Users' privacy must be protected by collecting only necessary
data, anonymizing or pseudonymizing personal information, and implementing
strict access controls. Compliance with regulations such as GDPR and CCPA is
crucial for handling user data responsibly.
7. User-Centric Design: IoT devices should be intuitive and easy to use, with
interfaces designed for a wide range of users. User feedback and usability testing
are essential for refining the user experience and ensuring that features meet
users' needs and expectations.
8. Edge Computing: Processing data at the edge of the network, closer to where it
is generated, can reduce latency, bandwidth usage, and dependency on cloud
services. Designing devices with edge computing capabilities can improve
responsiveness and efficiency in IoT applications.
9. Remote Management and Monitoring: IoT devices should support remote
management and monitoring capabilities to enable administrators to configure,
update, and troubleshoot devices remotely. This includes features such as
remote diagnostics, configuration management, and firmware updates over the
air (OTA).
10. Adaptability and Flexibility: IoT systems should be adaptable to evolving
requirements and changing environments. Designing modular and flexible
architectures allows for easy integration of new devices, sensors, and
functionalities over time.
