IoT has a strong association with web development and other advancements. And many programmers use the IoT framework to create an IoT Smart City.

Role of IoT in Smart Cities

Big regions can use IoT technology to improve various parts of their infrastructure and communal area.

To specify, such devices allow regional heads to control and monitor things easily, using the internet to communicate. Such technologies are useful around the world and are specific to sensors and similar devices.

Indeed, with how widespread the uses are, and the unlimited region it can encompass, using the Internet of Things for Smart Cities is valid. With its help, one can ensure the citizens are safe and enjoying a good infrastructure. Plus, there is lesser pollution and traffic in cities.

What Is A Smart City?

An IoT Smart City utilizes different forms of IoT devices to collect and analyze data. Some of the things that such devices derive the data from are meters, lights, and any connected sensors.

These technological cities undergo massive advancement in terms of public utilities, infrastructure, and other such services. Any iot app development company can help you in this regard.

People in charge of handling the operations of the city use the data they gather to access user needs and problem areas.

With the help of the internet, the city handlers can directly address their citizens too and understand what they require. Plus, they can keep a note on what is going on around the region, and ensure proper development.

Why There Is A Need Of Smart City?

More than 68% of the people today live in urban areas, and it would keep growing with time. Alongside this, the population is growing too, and many people are focusing on area development or displacing to cities.

In fact, estimates show that within the next thirty years, at least 2.5 billion more people would start living in cities. Owing to this, it is important to improve the economic, social, and environmental conditions with a bigger expansion.

In this concern, the need for IoT Smart Cities is visible, and many developers and individuals focus on it.

The Sustainable Development Goals (SDGs) agenda was brought forward at the United Nation in the concern of growing urbanization. 193 countries agreed to it but the development planning and the pace of it were relatively slower than planned.

Not only does an IoT Smart City help with improving the quality of life, but also expands on pre-existing features. One of the most important concepts in this concern is the main connective control system that works on Cloud.

Additionally, these are good for the ecosystem too, like using the natural power of solar energy to power things.

There are countless ways in which the Smarter Cities Solutions help the citizens as well. Like, streetlights that can notice parking spots and alert drivers looking for one.

Some bright LEDs warn people regarding disaster situations too, like heavy storms or traffic problems. Thus, a smart city is helpful in many ways including giving space, living conditions,  and much more.

Components Of Smart City

With a growing population all over the world, the consequences are seen in the ecosystems. In this concern, an IoT Smart City is a good choice as it consumes lesser resources and is also eco-friendly. There are certain components to this, and they are:-


The CyAM or City Air Management Tool is a software suite that is cloud-based, developed by Siemens. The algorithm of this works with a neural network (artificial), and that makes the weather predictions.

This includes a dashboard, on which you would receive the information regarding how the air-quality is and the pollution level.

When wondering What Technology Do Smart Cities Use, this one is highly helpful and it provides 90% accurate real-time forecasts.

The CyAM is good in calculating what the forecast emissions would show for the next 3-5 days. There are 17 measures in this that it uses to calculate the weather pattern for the upcoming days.

Due to this, there will be many consequences like speed limits assigned, low-emission zones introduced, and inexpensive public transport.

Smart Infrastructure

Investing in self-propelled cars and electric vehicles would cut down on the CO2 levels. That is what the Smart City Applications focus on, and the consumers should abide by.

Plus, a great part about the infrastructure of the smart cities is that it uses advanced technologies. These, in turn, try to be energy-efficient and eco-friendly. That’s where IoT Open Source Frameworks can come really handy.

Another great concern about the IoT Smart Cities is that they try to continuously improve and change themselves. There is a higher need of using digital technology to make buildings in urban areas more sustainable and energy-efficient.

Also, this infrastructure comes with smart lighting features, in order to save electricity and power. These lighting features automatically switch off or adjust brightness levels as an alert.

Smart Parking

Another of the good Smart City Examples in regard to the components is the smart parking factor. Using the sensors on the road, the drivers receive a report on their phone about the nearest parking space.

This component is not expensive either, which makes it ideal for smart cities of various locales and sizes. Someone driving would get feedback too from other people in the lane, and make easier parking decisions.

Traffic Management

One of the most important components of an IoT Smart City is the traffic management conditions. This is not easy in bigger cities as traffic congestion is more likely to occur on the roads.

But in a smart city, the traffic management feature includes sensors on the pavement that would send you real-time alerts.

Not to mention, these smart sensors would predict the traffic patterns too, depending on past traffic conditions.

Waste Management

Another good and useful feature of an IoT Smart City is the efficiency it uses in waste management too. It can reduce operational costs, and one way this is possible is because the waste collectors receive alerts of full bins.

Therefore, when there is a half-empty container, waste collectors do not have to get down and collect them. They would do so when they receive the notification that the waste bin, otherwise they drive by.

This is very good for saving fuel as well. The main reason that this works is because of the sensors that are present on the smart bins.

How To Secure Smart Cities?

It is true that smart road systems, monitoring systems, GPS-tracking systems, connected cameras, etc., improve one’s lifestyle.

However, with so many personal information syncing to the cloud, it leaves you vulnerable to data theft, hacking, etc. You need to be aware of IoT Security Challenges in detail.

Thus, it is crucial to safeguard the Smart Cities Internet of Things, and there are many ways to do so. Overall, there are four phases to focus on- integrity, availability, accountability, and confidentiality.

  • Integrity- An IoT Smart City relies on data, and it is important that it is correct and reliable information. While focusing on security, that is one matter to consider and ensure that the data is not changed.
  • Availability- While the data is important to protect, it is also necessary to ensure that you can access it when needed. For an IoT Smart City to work it is supposed to, one should focus on the collection and sharing process.
  • Accountability- While the system software should ensure safety and security, it is also the users’ responsibility to stay vigilant. Thus, they should themselves make sure not to let others use their login ID and other such user-specific points.
  • Confidentiality- A lot of the data that is shared comes from the users’ phones. And these devices contain a lot of private details, like sensitive personal messages, financial details, etc. When using the Smart City Examples, you should make sure that no third-party can breach it.

To make sure that your system is safe, use the help of ID management-centric solutions and high-end authentication features.

When these are present in the ecosystem, the data is more secure and identification is easier. Plus, they also safeguard the backend systems.

Smart City Architecture & Infrastructure

When creating new buildings and houses, a lot of the building managers wish to use Smart City Applications.

Using IoT solutions and devices, one can improve the quality and features of the buildings. Not to mention, such approaches are not too expensive either, making it a safe choice. The IoT Applications and Examples are proof of that.

More than half of the total building managers in the US alone know the need for IoT, with a majority of them already using it.

Many developers believe that a huge portion of building development and operation would improve within a few years through smart cities.

For example, one of the main areas where the Internet of Things for Smart Cities would work well is the lighting features. This would replace the use of LED bulbs, thereby saving energy and cost.

One of the main areas of concern that is common for smart cities is the use of smart grids. This infrastructurally and the architecturally thought-out system help to conserve resources.

For example, people in the European Union have started using Smart City Applications like IoT gas meters and electricity meters.

Examples Of IoT Smart City Infrastructure

Like heating appliances, building managers also see a need to improve upon elevators using IoT. While these are very helpful applications in building planning, most elevators do not run fast enough.

Due to this, people wish to utilize IoT technology to make elevators faster and safer. Allied Market Research predicted in 2015 that the market for smart elevators would rise from $12 billion to $23 billion within 5 years.

As for smart grids, Amsterdam has considered using solar panels and storage units in homes by connecting it to them.

This way, these devices in an IoT Smart City would store energy and then use them later during peak hours. Next, people can also choose to give the excess energy to the smart grid.

IoT Applications & Smart City Projects

In terms of using Smart City Applications, Europe is one of the leading countries in making interesting Smart City projects. In fact, the entire European Union urges the member nations to create and use smart city benefits.

Subsequently, the European Commission has kept 365 million euros aside to help facilitate this planning. Thus, Amsterdam is not the only example for IoT Smart Cities in this continent, although it is a notable one.

In Copenhagen, there is a bike traffic tracking program that uses sensors to see where the traffic is lesser. This gives the rider an easier view of the routes, in real-time. Also, it ensures faster travel and more safe commute throughout the city.

One of the major cities where Smart City projects that have seen improvement over the years is in Paris. Under this, Autolib grew in popularity after it started in 2011, and has around 3,000 vehicles and counting.

It is an electricity-based car-sharing program that uses GPS in a phone for tracking. Plus, there is the facility to reserve a parking space beforehand too displayed on the car’s dashboard.

In London, there is a similar IoT Smart City automobile service project, aimed towards finding parking spots easily. This way, drivers can easily and quickly find a place to park at, and not get stuck in congested traffic.

Smart City Projects
