Sustainable Smart Cities: Integrating IoT, Edge Computing, and Renewable Energy for Climate- Resilient Urban Infrastructure

Abstract

The rapid pace of urbanization has intensified challenges related to energy consumption, environmental degradation, and infrastructure resilience. Sustainable smart cities have emerged as a strategic solution to address these issues by integrating advanced technologies such as the Internet of Things (IoT), edge computing, and renewable energy systems. This paper proposes a comprehensive framework for climate-resilient urban infrastructure that leverages real-time data acquisition, decentralized computing, and intelligent energy management. The framework integrates IoT-enabled sensors for monitoring environmental and infrastructural parameters, while edge computing ensures low-latency data processing and efficient resource utilization. Renewable energy sources, including solar and wind systems, are incorporated into the urban grid to enhance sustainability and reduce carbon emissions. A case study simulation demonstrates improved energy efficiency, reduced operational costs, and enhanced system resilience under varying climatic conditions. The results indicate that the integration of IoT, edge computing, and renewable energy significantly improves urban sustainability and disaster preparedness. This research contributes to the development of intelligent, adaptive, and resilient urban ecosystems aligned with global sustainability goals and climate action strategies.
