Just imagine how exciting and amazing this world would be if everything around us is connected, it would not only save our time but also reduce our unnecessary tensions and stress.And since human-kind has evolved and developed many-folds, thus, we have a super-power technology to turn this into reality and that’s termed as “IoT” or “Internet of Things” - the connection of Physical World with the Cyber World . Sounds fascinating, isn’t it?
Now, let us see how it works in reality.
The Cyber-Physical system is configured or designed by following these functions:
The Cyber-Physical system is configured or designed by following these functions:
·
Connection
level:
It involves attachment-free or wireless communication, monitoring and recording
the physical conditions of the environment using sensors and organizing them at
a central location.
·
Conversion
level
(Data-to-information): Involves data-correlation, tracking of machine-failures,
malfunctions, reduces downtime (time when the machine is out of action) by
degradation and performance prediction.
·
Cyber
level:
Here the data are clustered for interpretation (has the ability to incorporate
Big Data Analysis by analysing it against business and other contextual data) ,
It builds a virtual model of process, product or service to head-off the
problems before their occurrence and to plan the future using simulations.
·
Cognitive
level:
It involves remote visualisation in which remote users can access, manipulate
share critical information. It also includes Integrated simulation and design
synthesis that would reduce development time and improve performance and also invites
collaborative diagnostics and decision making.
·
Configuration
level:
Involves self-configuration, self-adjustment and optimisation for recovery, any
kind of variation or disturbance.
We all can imagine the technology’s benefits. Just to prove
its varied applications some of the fields are listed below:
·
Agriculture:
The sensors can collect Information about the environmental conditions and can
be used to automate farming techniques.
·
Energy
management: The energy consuming devices can be remotely controlled and
scheduled.
·
Environmental
monitoring: IoT can be used to monitor air, water, soil conditions which can be
an effective aid.
·
Building
and home automation: can be used to monitor and control mechanical, electrical
and electronic s.
·
Medical
and healthcare: medical equipments can be monitored using sensors and they can
self-adjust without any manual-interaction.
These are just few which
could be mentioned.
This
technology has impressive characteristics.
Most
of the autonomous works includes cloud computing such as web-services , SOA(Service
Oriented Architecture) and thus
incorporates IoT technology.
The
IoT technology requires high scalability, involves high complexity, has the
ability to encode trillions of objects, thus it is largely dependent on
IPv6(Internet protocol version 6) (as all the devices will use an IP address as
a unique Identifier ) and various connection measures (from Wi-Fi, LTE advanced
to satellite communication and Ethernet cables)
Network
simulators like OPNET http://opnetprojects.com/opnet-network-simulator/
and TETCOS NetSim https://www.tetcos.com/
can be used to simulate IoT networks.
For
getting started into this field you need to have a basic understanding of electronics, sensors, microprocessors,
microcontrollers(Arduino UNO, Raspberry Pi, Banana Pi etc.)(its recommended
to start with Arduino though Raspberry Pi has a much better performance), SoCs(System
on Chips) and programming languages (like python, embedded C ,Java, PHP ,Swift)and of course you need
to know how networking works. If you want to learn and contribute to its
development or wanna make something incredible here are some top links that you
can follow(all of them are free):

(for the book lovers)
It
has the power to transform and revolutionise everything, our lifestyle, our
priorities, our management our surroundings , and everything that affects us in
one or the other way. Though it has challenges, like rising complexities and
space availability etc., but once sorted this can go beyond our imagination.

In today’s world, businesses are faced with many challenges to maintain a market edge over other competitors.Internet of things analyticsis an emerging player in this field and has the potential to completely change the way businesses operate. With the rising smart devices and technological advancement all around us, internet is used to describe almost everything.
ReplyDeleteWhen you are measuring data, there are two different types of analysis you can perform. The first type is descriptive analyticswhich gives you a broad view of the data. Descriptive analytics is a great first step for understanding your data. It can show you patterns in the data, help you better understand your customers, and reveal other useful insights.
