Smart City Concepts, Features and the Role of Internet of Things: A Review

By 2050, almost 70% of the total world population is estimated to migrate to urban areas. To accommodate such a large population, the need to build smart cities all over the world is the need of the hour. To accomplish this goal, a lot of work needs to be done in the fields of various smart city concepts for better management of resources and to reduce the problems faced by the public in general. With this vision, many researchers around the world are working to build up efficient technologies, that would make the concept of smart cities feasible. In this direction, some technologies, like ambient intelligence, etc. exist but are not coupled with the Internet. On the other hand, the Internet of Things (IoT) is an emerging technique, that is tightly coupled with the Internet. This makes IoT one of the popular techniques to implement the concept of smart cities easily and efficiently, and various applications of IoT are capable of formulating the concept of smart cities into existence. This paper focuses on a detailed survey of smart city concepts, features, and the role of IoT in building smart cities.
