In recent years, there has been an increasing trend in population moving toward urban regions and large cities. It is envisioned that the future cities around the world will be smart cities. Plenty of efforts have been made to improve the quality of inhabitants of smart cities by integrating different technologies in their day‐to‐day lifestyle. These improvements include advancement in public facilities such as water systems, transportation systems, and the electricity system. In smart cities, information and communication technologies (ICT) will play a vital role for providing services in urban environments. These services include real‐time monitoring and control through wireless sensor and actuator networks. Smart grids (SGs), intelligent transportation systems (ITS), the Internet of Things (IoT), electric vehicles (EVs), and wireless sensor networks (WSNs) will be the building blocks of future smart cities. “Smart grid” refers to the modernization of the traditional power grid by incorporating two‐way digital communication support at the generation, transmission, and distribution levels. “Intelligent transportation system” refers to making the vehicular traffic smarter by reducing congestion, optimizing fuel consumption, choosing shorter routes, and improving safety, as well as allowing self‐driving cars by using communication and sensing technologies. The “Internet of Things” refers to a worldwide network of interconnected objects uniquely addressable, based on standard communication protocols and allows people and things to be connected anytime, anyplace, with anything and anyone, ideally using any path/network and any service. The IoT can be very useful for resource management in the context of smart cities. Wireless sensor networks are composed of sensor nodes capable of performing sensing. The application of WSNs ranges from environmental monitoring to forest fire detection and from power system applications to disaster, security, emergency applications in urban environments. Electric vehicles aim to reduce vehicle emissions and can also be envisaged as mobile power stations, which can introduce the consumer‐generated energy to the main electrical grid. All these technologies will somehow help to build a smart city.
