IoT Applications for Smart Cities

Internet of Things, commonly known as IoT is engineered to add the ability to transfer and share data across networks without the need for human intervention. IoT devices include home appliances, electric meters, vehicles, security systems, speaker systems, etc. These devices are equipped with software and sensors that help the transfer of data which is then processed to make a logical decision, adding smartness to the device.

To serve the newer demands of smart cities, the Government is turning to IoT innovations that have the potential to improve every aspect of Smart living. Some of the current IoT applications include city surveillance, smart parking, traffic monitoring, waste management and smart lighting.

As per IEEE Standards Association, Smart City is defined as“As world urbanization continues to grow and the total population expected to double by 2050, there exists an increased demand for intelligent, sustainable environments that reduce environmental impact and offer citizens a high-quality life. A smart city brings together technology, government and society to enable a smart economy, smart mobility, a smart environment, smart people, smart living and smart governance.” (Source:

IoT is revolutionizing the way smart cities function especially in the following areas:

Efficient Water Supply

Internet of Things can possibly change the manner in which urban communities use water. Smart meters can facilitate leakage detection and reduce wastage. Additionally, these meters can be intended to furnish occupants with continuous access to data about their utilization and water supply.

Smart Traffic Management

Due to rapid urbanization, traffic problems are drastically increasing. Traffic congestion is a massive problem and it is deteriorating as the number of vehicles are increasing. With the help of IoT, it is going to be much easier to handle traffic congestion with smart traffic signals that will help in better management of traffic control. People can collect and share data from their mobile phones, vehicles and road sensors to monitor real-time traffic incidents. When routes are blocked, drivers can get an alert message about the incidents and re-direct to a different route.

Reliable Public transportation

Whenever there are roadblocks or closures, transportation is disrupted. IoT devices can provide real-time insights needed to implement plans to tackle such problems and have safe, reliable and efficient public transportation.

Energy-Efficient Buildings

IoT innovation is making it simpler for constructing energy efficient building structures. With the use of IoT, the devices can be connected to a Smart Management Application thatcontrols nonstandard heating, cooling, lighting, and fire-safety systems.

Smart Parking

GPS data from smartphones and video monitoring  (or sensors embedded on parking spots) can assist a car driver to find an emply parking spot. The data is real time, and it helps tocreate a virtual parking map what will let the car owners know when the closest parking spot becomes free. The drivers will receive a notification on their phone to find the parking spot.

These kind of systems are already installed in cities around the world and have been successful in assisting effective utilisation of parking spaces.

Smart Street Lighting

IoT devices can be implemented for the maintenance and control of streetlamps in a more cost-effective way. Sensors with the help of a cloud management solution can help in controlling and scheduling theswitching operations. Smart lighting solutions can be implemented with sensors to keeptrack of movement of people and vehicles.With the help ofthis data, the street lamps can adjust the lighting to either dim, brighten or switch off or on automatically based on the environment.

Healthy Environment

IoT devices can also be used to keep the cities clean and safe. Cities can implement various strategies like defining parameters which are important for a safe and healthy surrounding. Sensors can be incorporated to measure the quality of the water by examining the level of pH, air, soil, and etc.

Waste Management

IoT devices like sensors can be attached to a garbage container that gathers the data about the level of waste in the container. This sensor upon a certain threshold will give an indication tothe waste management solution and send a notification to the truck driver’s mobile application.


Perhaps, the major advantage of a smart city is the collaboration for sustainability. Everyone has to work together for the future he or she desires. The aforementioned benefits are just a fraction of what the internet of things has to offer us.

IoT has the potential to bring communities around the world into “smart cities”. It will improve our standard of living and increase safety and better traffic control, efficient use of energy and lower levels of pollution. With sensors attached to every vehicle, equipment’s IoT systems will revolutionize the way we live. The possibilities of IoT are endless as it produces invaluable data for businesses, emergency services, parking management, etc.
