ABSTRACT
The smart city, present, and future promises economic
growth, as well as, competitiveness presented in highly
educated talent, seamless electronic connections and high-
tech industries. Other terms used for the same include
“cyber Ville,” “electronic communities,” and “intelligent
cities.
The shift in paradigm to smart cities stems from socio-
economic factors such as economic restructuring, climate
change, pressures on the public finances, aging populations,
as well as, entertainment, and online retail. Thus, creating
and sustaining conditions suitable for learning and
innovation is an essential prerequisite in the existence of
smart cities (Dickey, 2017). In the same vein, for European
countries to achieve Europe’s 2020 goals of climate change,
innovation, employment, employment, energy, and poverty
reduction, progress in the smart city would be welcome to
any interested party, specific questions stand out. For
example, how much urban investment will be responsible
for achieving in the future? What are the factors to
consider? What are their sustainability or plans?
The competition among cities in maintaining and
attracting new residents, visitors and businesses translate to
constant attention in providing a higher quality life and a
viable economic climate. While leftists might cite tight
budgets, challenges frequented by legal systems and scarce
resources as impediments to innovative and new
technology, forward-thinking leaders see a niche in
employing big data and the analytics for more profound
insights (Rønne, 2018). They believe that these problems
can be cured by the use of the cloud to collaborate among
different agencies, mobile to gather, address and
disseminate issues as well as the use of social technologies
to better engage with citizens.
To achieve a smart city, the legal framework
should allow the use of Internet of Things (IoT) as mediums
for the city management and public administration. For
example, from 2009, the local government in Rio has been
working to overcome financial restrictions through the
introduction of innovation and management styles as those
employed by the private sector (Schuler, 2016).
At the heart of smart cities, existence is the role of
urban planning. Urban economists concur that resilience
and sustainability in regional development, urban planning
and information society is not only the thumbprint to the
projects but also the catalyst to their survival. IoT and
telecommunication companies such as Cisco, IBM, and MS
have come up with new solutions for smart cities to
facilitate smartcities (Siano, Shahrour &Vergura, 2018).
While IBM introduced its Smarter Cities as a stimulus to
the quality of life in the cities and economic growth and
development in the urban ecosystem, Cisco would laud the
Global Intelligent urbanization initiative that enables cities
all over the world to use networks as their fourth utility in
the economic development and integrated city management.

INTRODUCTION
The constantly increasing proportions of urbanization have
been explicitly observed in recent times and estimates
suggest that almost 70% of the global population amounting
to more than 6 billion people would be residing in urban
areas or nearby locations by the year 2050 (Choudhary,
Sathe & Kachare, 2017).
The substantial rise in population density in urban locations
has also led to an increase in the demands for sophisticated
services and infrastructure needed for addressing the
requirements of residents. Therefore, the preferences for
smart cities could be conveniently validated in this case
owing to the credible implications for social, environmental
and economic security alongside the use of information and
communication technologies for improving awareness,
competency and interactivity of the services of the city and
its monitoring (Choudhary, Sathe&Kachare, 2017).
The prospects for smart cities are being driven profoundly
by the expanding scope of Internet of Things (IoT) which
can be considered as an integration of available internet
accessibility into a wide network of interconnected devices
and objects that are not only capable of gathering
information from the surrounding environment through
sensing alongside engaging in interactions with the physical
world but also comply with the present internet standards
for provision of services for analytics, applications and
information transfer. In this section, the problem associated
with using Internet of Things (IoT) for development of
smart cities with respect to the recent advancements as well
as the emerging challenges would be discussed.
Domain: IoT for smart cities:
Prior to discussion on the problems and challenges
encountered in the specific concerned domain, it is essential
to obtain a conceptual understanding of Internet of Things

and its application in the case of developing new smart
cities. The general concept that is associated with the IoT is
the ubiquitous presence of different objects such as sensors,
mobile phones, actuators and Radio-Frequency
Identification (RFID) tags around us. With their individual
addressing schemes, these devices would be able to
coordinate with each other for accomplishing common
goals (Choudhary, Sathe&Kachare, 2017, p 1).
The empowerment of IoT through adapting different
facilitating devices such as actuator nodes and embedded
sensors for converting the available fixed and mobile
networking infrastructures into a fully integrated network
for the future. Wireless sensor networks (WSNs) that form
an integral aspect of sensing-actuation support in IoT could
be integrated effectively into urban infrastructure thereby
providing a digital blueprint of the city. The information
that is garnered through WSNs could be collated across
different applications and platforms that lead to the
development of a common operating picture (COP) of the
city (Choudhary, Sathe&Kachare, 2017, p 1).
The concern for addressing the problems identified in use
of IoT for smart cities could be profoundly observed from
the benefits of IoT for smart cities that cannot be
undermined in any scenario.The applications of IoT
facilitate prolific assistance for individuals, businesses and
societies to explore new opportunities for accessing
substantial volumes of data alongside introducing new
applications and services that can contribute to reduction in
levels of power consumption, improvement in efficiency of
the society and creation of a cleaner environment (Ahlgren,
Hidell& Ngai, 2016, p 2).
One of the promising examples of the application
of IoT in moderation of urban infrastructure could be
identified in the utilization of mobile phones and smart
meters for regulating energy consumption that is
responsible for higher energy efficiency as well as
individual control. Furthermore, smart energy solutions and
smart grids could be leveraged by people for measuring,
monitoring, controlling and influencing personal energy
consumption alongside capitalizing on abilities for
independent production of energy (Ahlgren, Hidell& Ngai,
2016, p 2).
PROBLEM OR CHALLENGES:
The primary challenges that are identified in the adoption of
IoT for smart cities are vested in open research issues. The
discussion on these challenges would be explicitly
productive for facilitating research direction to new
ventures in this domain. The first aspect that should be
discussed in the case of implementing IoT for smart cities is
vested in security, privacy and trust. Since smart cities are
associated with provision of Internet connectivity to a wide
assortment of devices, security could be accounted as a
formidable issue as estimates have suggested that 70% of
IoT devices in smart cities are vulnerable to attacks owing
to factors such as insufficient software safeguards,
inadequate protocols for encrypted communication and
improper standards for authorization. Therefore, it is
essential to address specific issues in the establishment of
an IoT-based smart city which include active and competent
decentralized trust management system, privacy-aware
communication of user data, string privacy measures for
ensuring the trust and consent of users and utilization of
risk assessment frameworks for identifying existing as well
as threats of emergent attacks on the basis of vulnerabilities.
Interoperability is also a formidable challenge in
establishing an IoT-based smart city which can be defined
as the capability of different devices and networks to
engage in communication for exchanging crucial
information. The consideration of interoperability between
two devices from different domains as a major roadblock
for accomplishing IoT success by the World Economic
Forum further strengthens the necessity for addressing this
issue urgently.
The primary cause for issues with interoperability could be
identified in the lack of universal standards. The possible
measures that could be implemented for addressing the
issues with interoperability is to recognize the issues at
different levels such as platform, network, device or
application and utilization of a holistic and competent
approach for facilitating connectivity to numerous IoT
devices. In the case the example of standardizing FIWARE
and oneM2M could be presented as a prolific initiative for
addressing interoperability issues arising in context of the
collaboration between the largest standardization bodies of
the world such as OMA, ETSI and 3GPP.
The operation of IoT devices is profoundly associated with
the requirement for a continuous source of energy thereby
leading to the challenge of cost and battery life. The
possible approach that can be implemented in this case
would be the implementation of devices that provide the
feature of low power consumption at lower costs
(Mehmood et al., 2017, p 21).
The advances in this context could be realized only through
progress in the domain of micro-electronics and wireless
communication. Continuing with the problems that might
arise in establishment of IoT-based smart cities, the other
noticeable issues include Big Data Analytics and
connectivity in IoT (Mehmood et al., 2017, p 22).
The prominent challenges that can be observed in this case
include references to the requirements for respecting the
privacy of users during data analysis, provision of
infrastructure for collection, storage and analysis of a
considerable amount of data, provision of connectivity to
high-mobility devices and ensuring connectivity among the
extensively deployed devices even in the lack of
communication networks (Mehmood et al., 2017, p 23).

LITERATURE REVIEW
According to research conducted by Nanni, Benetti&
Mazzini, (2017) Internet of Things offers cities new
opportunities to use data to manage the traffic, reduce
pollution, better utilize the infrastructure and protect
citizens' safety(Nanni, Benetti& Mazzini, 2017). IoT help
cities to make the several digital opportunities, the Smart
City Internet of Things are a fully integrated scalable and
modular framework to effectively deliver as well as to
manage smart city services. Saadeh, Sleit, Sabri &
Almobaideen, (2018) states that the “fully integrated”
approach meets the essential requirements of a shared,
secure and scalable interconnected environment each
'thing' can communicate with each other to make
tomorrow's cities smart, secure moreover the sustainable. It
is easy to see that cities can benefit from technological
advances in the use of the Internet of Things(Saadeh, Sleit,
Sabri&Almobaideen, 2018). It's also easy to see that as the
city continues to grow and more devices are added to the
infrastructure, the amount of data will be huge. In order to
manage these needs and make full use of new technologies,
cities will need information management systems.

As the IoT began to leave its mark in the technology
industry furthermore not only completely changed
consumer goods, however also completely changed all
aspects of human life (authors suggest that things from
street lights to cars to the seaport will eventually be "smart,
IoT importance lies, according to authors point out, in cloud
computing and the sensors inbuilt in technology. Whereas
the smart gadgets have the ability to "communicate" or to
simply communicate with different smart gadgets, they
likewise have ability to collect and to observe data (as
opposed to sensors) and examine the real-time data. The
following is a painful example of the author's ability to
monitor and analyze real-time data through the smart
infrastructure novelty.

Smart technology deployment like smart technologies,
smart chips, and smart phones has promoted in the smart
cities development. It includes diverse smart systems, for
example, smart homes, and smart gadgets. These intelligent
systems must be connected to a large number of unique and
smart objects in a largest IoT network. Trusted
communication between the IoT objects is a fundamental
goal of IoT security. In this article, the authors have devised
architecture to address diverse IoT issue or challenges for
instance scalability, heterogeneity, and mobility. In
addition, the architecture is also supported by associability
of the proposed signature verification protocol which is
completely based on hierarchical elliptic curve uniqueness.
The authors conclude that proposed architecture supports
the design of the Internet of Things in smart cities more
than its competitive architecture.

smart cities is to get the right information at the right place
and on the right equipment, making city-related decisions
easier and providing citizens with faster, faster ways. In this
paper, the authors propose an IoT-based system to
implement smart cities, promote governments and citizens,
and make real-time decisions based on current urban
scenarios. The author concludes that in order to process
large amounts of data, we use the Hadoop ecosystem and
Spark at the top level at a very high speed. Existing
intelligent system data sets are used to test and evaluate the
efficiency of the system. In the future, we plan to use a
practical intelligent system deployment system to test the
actual implementation and feasibility of the system.

REQUIREMENTS FOR THE PROJECT
Based on the literature, the requirements for the project are
security concerns of smart cities, privacy concerns of smart
cities and implementation of IoT in smart cities security
concerns of Smart cities are selected to work with.
MODIFIED PROBLEM STATEMENT
The main challenges identified when using the Internet of
Things in smart cities are attributable to open research
issues. There are many opportunities for the implementation
of the Internet of Things, but we cannot ignore the threats
and difficulties we face. Since the Internet of Things is
expected to have a major impact on our lifestyle, we need to
make sure we understand the risks and challenges involved.
Security and privacy are considered to be the main threats
to our implementation of the Internet of Things. While
many people discuss different opportunities for the Internet
of Things, everyone agrees that security must always be
achieved. Everything is managed online, which means
anyone with access to computers and the Internet can
control it.
CURRENT AND PAST TECHNIQUES OR
TECHNOLOGIES USED TO SOLVE THE PROBLEM
More importantly, the Internet of Things will be a key
innovation to solve this problem. In addition, support
technologies have reached maturity, allowing the actual
implementation of the IoT solutions moreover the services,
starting with field trials, with the hope of helping to
eliminate the uncertainty that still hampers the large-scale
adoption of the IoT paradigm. With the advent of personal
data, the security and privacy of communications and
services are lost, and unnecessary communications become
paralyzed. As new devices and heterogeneous networks
diversify, the overall problem is further exacerbated. Users
are faced with various methods and devices for accessing
the digital world and can no longer be assumed. Urban IoT
systems require a set of link layer technologies due to their
inherent large deployment area. These technologies can
easily cover a broad geographical area while supporting a
large number of small flows generated by very high
aggregation. For such reasons, the link layer technology for
realizing the IoT system is divided into constrained and
unconstrained technologies.

types, communication protocols, standardization efforts,
chief service providers & many more.
Serviced providers – The innovation of IoT is
becoming popular day by day and its application
over smart cities will grow by billions of dollars
by the year 2020. The annual growth will be
around 16 billion. Internet of Things carries
immense potential of enhancing the revenue for all
service providers (Mehmood et al., 2017). This
communication paradigm is avant-garde that many
renowned service providers have started
discovering. Ericsson, Orange, Nokia are some
service providers that can out forward numerous
platforms for the applications related to smart city
such as e-healthcare, ITS, home automation,
logistics & a lot more.
Communication protocols – An Iot based smart
city is bound to depend on manifold
communication protocols for the transportation of
data between backend servers & devices. Some of
the short range technologies are Wi-Fi, ZigBee,
WiMAX, Bluetooth, etc. These technologies are
utilized in vehicular communication, e-healthcare
& metering. The wide range communication
technologies are LTE, GSM, and GPRS. These
technologies are utilized in mobile e-healthcare,
infotainment services, V2I, smart grid, etc. The
protocols and the various radio technologies can
be utilized for:
Backing up smart city applications for
ensuring interoperability among
numerous operators
Radio technology is equipped with star-
based communications that presents a
scalable worldwide network for
discovering smart city applications with
consumption of low power.
Network types – Network topologies are required
for smart city applications for establishing
autonomous environments. These capillary
networks render services over minute ranges.
WPANs, WLANs & BANs are some of the
examples of wireless networks. Home automation
& e-healthcare services are some of the application
areas. Applications such as waste management,
ITS utilize WANs, mobile communication &
metropolitan area networks.
Activities of standard bodies – The device interoperability
requirement by smart city applications is a highly vital one
along with deployment of manifold IoT devices. Smart city
applications can then only be facilitated on a huge scale
when renowned government bodies like oneM2M, IETF,
OMA & 3GPP participate for developing the standards.
Offered services – Within the arena of Iot there
are manifold services that help in influencing city
administration with decrease in operational costs.
Smart lighting, waste management & waste are the
offerings.
Requirements – There are diverse applications
within the sphere of IoT in a smart city that again
leads to vast requirements. IoT based applications
& solutions are always anticipated to be highly
secured, flexible, low cost, Quality-of-Service,
multivendor interoperability, etc. These requisites
can be fulfilled with the implementation of new
techniques. For instance, huge IoT traffic can be
managed with traffic modeling. This combined
modeling approach is better than conventional
approaches where IoT devices can access networks
individually for putting out & receiving messages.
Internets of Things open source platforms
Multi-vendor interoperability can then only be achieved
when information is shared with the help of open source
realizations (Ilunin, 2018). There exit open communities
that render rapid development platforms just for smart
cities.
OCEAN – Open alliance for iot standard is a
worldwide alliance that brings in open source
realizations for smart cities that are based on
Internet of Things standards. With this the
commercialization of platforms, services &
products will also take place for the extensive
acceptance of IoT standards. The source code will
be released by OCEAN as open source that will
lead to the collaboration of developers & vendors

is the development of a data hub surrounded by the
city that handles & amalgamates data that is
acquired from manifold smart devices. The project
also focuses on the control of carbon emissions
CHALLENGES RELATED TO OPEN RESEARCH
The adoption of the Internet of Things for smart cities will
bring forth advancements but there will be open research
challenges & issues as well (GoodWorkLabs: Mobile App
and Software Product Development 2016, 2018). By
throwing light on these challenges, new directions can be
offered to researches in the upcoming time.
Interoperability The ability by which two
diverse devices interact with each other for
information exchange is known as interoperability.
IoT devices that are incorporated in smart cities
come from wide-ranging domains like intelligent
transport, smart metering, monitoring and a lot
more. Interoperability is something that will be
responsible for connectivity amidst devices in a
smart city. But this is an obstacle for IoT success
as well as per World Economic Forum as there is a
lack in universal standards. Solving these calls for
the identification of these issues at varied levels
such as device, platform, communication, network,
application, etc. The challenges can be addressed

with an intelligent approach for offering easy
connectivity to many IoT devices.
Big Data Analytics – It is one of those research
directions that have a major role to play in IoT
based smart cities. Smart cities with the potential
of connecting many devices will offer massive
data amount for analysis. Both from user private
data and surrounding environments, this data can
amalgamate information. Intelligent techniques
will be required for this data analysis. For
example, information can be easily analyzed with
the help of deep learning algorithms whose
production is done by devices that are locally
connected. Major challenges that must be
addressed are:
The need for offering computation power
for extracting new knowledge from data
Respecting user privacy while data
analysis is being done
Need for adequate infrastructure for
collecting, storing and analyzing huge
data amounts
Presence of data anonymity for
confidential data
Security – All IoT devices require security that
has to be maintained at all costs. Security truly
becomes a critical challenge as all smart cities
offer Internet connectivity to various devices. The
devices can be at risks due to vulnerabilities like
poorly encrypted communication protocols,
inadequate authorization and a lot more. The
designing of a successful smart city based on IoT
calls for the addressing of the following issues:
Presence of robust privacy measures for
ensuring the consent and trust of the user
Fabricating efficacious security solutions
for guaranteeing data authenticity. With
this, a secured communication can also be
offered between cloud-dependent
application centers & IoT devices
Designing a sufficient and active
decentralized system of trust management
User data must be offered with privacy
aware communication
Studying the freshly emerging attacks
with risk assessment that are based on
threats and vulnerabilities. One of the
risks assessments has also been put
forward by ENISA that recognizes the
probable emerging attacks.
CONCLUSION
This paper carries the facts about the recent trends in IoT
based smart cities model. A classification has been carried
out for the Internet of Things enabled cities that are based
on service providers, protocols, standard bodies & network
types. Based on this study, we can conclude that
applications of smart city depend on wireless technologies
like LTE A/LTE, WAVE, 6LoWPAN & a lot more.
Researchers can also benefit from the study as we have
spoken about open Internet of Things platforms. Some case
studies of recent IoT deployments are also presented for
revealing the augmenting development towards IoT
deployments. The last but not the least, open research
challenges are also addressed like low cost, security,
interoperability, big data analytics that require considerable
attention and concern from various research communities.
