I.Introduction
Each development stage of world history is associated with revolutions in science and
technology. And today, the Internet of Things revolution has created significant changes to
humanlifeinthepresentandinthefuture.WiththedevelopmentoftheInternet,
smartphones and especially sensor devices, the Internet of Things (IoT) is becoming a new
trend of the world. IoT is defined as devices that are able to connect to the Internet. You enter
the house, unlock the door, the lights will automatically turn on where you stand, the air
conditioner will automatically adjust the temperature, the music will automatically turn on to
welcome you... things only in sci-fi movies, are gradually becoming reality with IoT technology.
My assignment includes four parts:
Explore various forms of IoT functionality.
Review standard architecture, frameworks, tools, hardware and APIs available for use in
IoT development.
Investigate architecture, frameworks, tools, hardware and API techniques available to
develop IoT applications.
Finally, determine a specific problem to solve using IoT.
II.Explore various forms of IoT functionality
1.What is the Internet of Things?
The term “Internet of Things” (IoT) is now widely used, but so far there is not unique common
non-biased definition or understanding of what this term encompasses. There are many
different definitions of the expression “Internet of Things” which however have in common the
feature that is has to do with the integration of the physical world with the virtual world of the
internet. In its simple form, IoT may be considered as a network of physical elements
empowered by:
Sensors: to collect information.
Identifier: to identify the source of data (e.g., sensors, devices).
Software: to analyze data.
Internet connectivity: to communication and notify.
~6~
The Internet of Things (IoT) is a system of interrelated devices connected to a network and/or
to one another, exchanging data without necessarily requiring human-to machine interaction.
In other words, IoT is a collection of electronic devices than can share information among
themselves. Examples include smart factories, smart home devices, media monitoring devices,
wearable fitness trackers, smart city infrastructure, and vehicular telematics.
Actually, IoT is distinguished in three interaction categories:
People to people IoT.
People to things (objects, machines) IoT.
Things/ machines to things/machines IoT.
Figure1. Internet of Things
“Things” refer in general to everyday objects that are readable, recognizable, locatable, and
addressable via information sensing devices, and/or controllable via the Internet, irrespectively
of the communication means employed (wireless LAN, WAN, etc.).
Some companies (e.g., Cisco) refer to IoT as the IoE (Internet of Everything) with four key
components: people, process, data, and Things. In this case, IoE connects:
People: Connecting people in more relevant ways.
Data:Converting data into intelligence to make better decisions.
Process: Delivering the right information to the right person or machine at the right
time.
~7~
Things: Physical devices and objects connects to the Internet and each other for
intelligent decision-making, often called IoT.
Figure2. IoT – more complete definition
2.Internet of Things Characteristics
The fundamental characteristics of the IoT are as follows:
Connectivity:Connectivitymakespossiblenetworkaccessibilityandcompatibility.
Anything can be interconnected with the overall IoT communication and information
facilities. Compatibility means that “things” have the common ability to generate and
consume data.
Safety: IoT must be designed to ensure the security of personal data, physical safety and
human health. Secure endpoints, networks, and the data in transit, implying that we
create a security model at scale.
Heterogeneity: The devices in the IoT are heterogeneous as based on different hardware
platforms and networks. They can interact with other devices or service platforms
through different networks.
Dynamic changes: The state of devices change dynamically, (e.g., alternating connection
and disconnection, changing position and speed, etc.).
Tremendous scale: The number of things and IoT devices that communicate and interact
with each other, and have to be managed, is at least one order of magnitude bigger
than that of the present internet.
