Internet
of Things (IoT) is a new paradigm that has changed the traditional way of
living into a high tech life style. Smart city, smart homes, pollution control,
energy saving, smart transportation, smart industries are such transformations
due to IoT. A lot of crucial research studies and investigations have been done
in order to enhance the technology through IoT. However, there are still a lot
of challenges and issues that need to be addressed to achieve the full
potential of IoT. These challenges and issues must be considered from various
aspects of IoT such as applications, challenges, enabling technologies, social
and environmental impacts etc. The main goal of this review article is to
provide a detailed discussion from both technological and social perspective.
The article discusses different challenges and key issues of IoT, architecture
and important application domains. Also, the article bring into light the
existing literature and illustrated their contribution in different aspects of
IoT. Moreover, the importance of big data and its analysis with respect to IoT
has been discussed. This article would help the readers and researcher to
understand the IoT and its applicability to the real world. The Internet of
Things (IoT) is an emerging paradigm that enables the communication between
electronic devices and sensors through the internet in order to facilitate our
lives. IoT use smart devices and internet to provide innovative solutions to
various challenges and issues related to various business, governmental and
public/private industries across the world . IoT is progressively becoming an
important aspect of our life that can be sensed everywhere around us. In whole,
IoT is an innovation that puts together extensive variety of smart systems,
frameworks and intelligent devices and sensors. Moreover, it takes advantage of
quantum and nanotechnology in terms of storage, sensing and processing speed
which were not conceivable before hand . Extensive research studies have been
done and available in terms of scientific articles, press reports both on
internet and in the form of printed materials to illustrate the potential
effectiveness and applicability of IoT transformations. It could be utilized as
a preparatory work before making novel innovative business plans while considering
the security, assurance and interoperability.
