ABSTRACT
Due to various fast technological innovations, the world is swiftly changing to meet emerging problems and moving toward mechanization. The use of various Internet of Things (IoT) devices is expanding, and every activity becomes a component of the network, culminating in cities that are becoming smart cities. Since the concept's inception, the IoT has been identified as a smart city's key infrastructure. Cities all across the world are looking to modern communications and technology to help them manage resource restrictions. Given that more than 65% of US online users feel at ease with the idea of living in a smart home, adoption of this technology will only grow in the coming years. As population and urbanization continue to expand in the next years, many towns may look to technology and smart networks to help them manage resource constraints. Cities, in particular, may grow to rely on smart city technology, which is a component of the IoT. The notion of the IoT mainly refers to the constantly rising number of electronic gadgets – now numbering in the billions – that can interact and communicate with others across the world via connection and can be tracked and controlled from afar. It entirely comprises sensors and smart devices. At the technical level of IoT, for example, weather data is acquired. The IoT gives cities a new way to use data to control traffic, cut pollution, make significant investments in technology, and keep inhabitants safe and clean. Furthermore, there are currently just a few descriptions of the many IoT applications in smart cities. This chapter aims to give an overview of different applications of IoT in smart cities.
