Abstract
Urbanization has accelerated rapidly in recent decades, resulting in increased pressure on cities to manage infrastructure, resources, and public services efficiently. Traditional urban systems are often unable to cope with rising population density, environmental degradation, traffic congestion, energy demand, and waste generation. In response to these challenges, the concept of smart cities has emerged as a sustainable solution that integrates digital technologies with urban governance and infrastructure. Among these technologies, the Internet of Things (IoT) plays a critical role by enabling real-time data collection, monitoring, and intelligent decision-making.
This study examines how IoT-based smart city initiatives contribute to sustainable urban development. It explores the application of IoT in key sectors such as energy management, water conservation, waste management, transportation, and public governance. Using a descriptive research design, primary data was collected through a structured questionnaire to understand public awareness, usage frequency, and perception of IoT-enabled services in cities. Secondary data from journals, reports, and research articles were also reviewed.
The findings indicate that IoT-driven smart city solutions significantly improve resource efficiency, reduce environmental impact, and enhance urban living standards. However, challenges such as high implementation costs, data privacy concerns, technological complexity, and lack of digital literacy remain major barriers. The study concludes that smart cities can achieve long-term sustainability only through integrated planning, strong governance, citizen participation, and continuous technological adaptation.
