Abstract : As urban populations continue to grow and infrastructure demands intensify, cities across the globe are increasingly adopting technological innovations to enhance sustainability, efficiency, and overall quality of life. The Internet of Things (IoT) has emerged as a key enabler in the evolution of smart cities—urban environments that utilize interconnected devices and data analytics to streamline operations, actively engage citizens, and minimize environmental impact. This article examines the pivotal role of IoT in smart city initiatives, with particular emphasis on its applications in infrastructure management, urban mobility, resource optimization, and energy efficiency. Through case studies and technological analysis, the study highlights how IoT is driving the evolution of intelligent, responsive, and inclusive urban ecosystems. The Internet of Things (IoT) is fundamentally reshaping urban landscapes by connecting infrastructure, devices, and people. As cities grapple with overpopulation, environmental degradation, and resource constraints, IoT provides data-driven, automated solutions that support more efficient, livable, and sustainable environments. This paper explores how IoT is applied in smart cities, outlines its benefits, identifies implementation challenges, and presents a future outlook with recommendations to promote security and resilience in smart city ecosystems.

Keywords : Smart Cities, Internet of Things, IoT, Urban Development, Infrastructure Management, Smart Transportation, Sustainable Energy, Predictive Maintenance, Data Analytics.
