Abstract

The rise of “smart cities” made possible by the IoT is revolutionizing cityscapes by boosting public services, maximizing the use of available resources, and generally enhancing people’s quality of life. A smart city creates responsive, sustainable, and efficient settings by fusing cutting-edge IoT technology with conventional urban processes. Sensors, RFID, MQTT protocols, and Raspberry Pi devices are some of the essential technologies discussed in this article as it pertains to the IoT and its function in smart cities. Key domains such as infrastructure management, governance, transportation, energy, healthcare, waste management, and public safety are analyzed through case studies from global implementations. The study highlights major challenges, including data privacy, scalability, interoperability, and security, that hinder IoT adoption. It also explores future trends like AI, machine learning, and 5G as enablers for next-generation smart cities. By addressing these challenges and leveraging advanced technologies, IoT can pave the way for sustainable urban growth and a citizen-centric approach to urban development. Future trends in IoT, including an integration of AI, ML, and 5G, are also explored as enablers for the next generation of smart cities.
