IoT Based Smart City – Applications, Challenges and Future Treads

Abstract

The Internet of Things (IoT) is a transformative technology enabling smart city development through real-time data collection, intelligent automation, and seamless connectivity. Smart cities leverage IoT to enhance urban infrastructure, optimize resource utilization, and improve citizen services. Key applications include smart transportation, energy-efficient buildings, intelligent waste management, and real-time environmental monitoring. However, IoT-based smart cities face significant challenges, including data security, interoperability, scalability, and high deployment costs. Addressing these challenges requires robust cybersecurity frameworks, standardized protocols, and advanced data analytics techniques. Future trends in smart cities involve AI-driven automation, 5G-enabled IoT networks, edge computing, and blockchain-based security solutions. This paper explores IoT applications in smart cities, discusses existing challenges, and highlights future directions to achieve sustainable and intelligent urban environments.
