IEMS: An AI-Framework Fusing IoT, Deep Learning, and LLMs for Multi-Domain Urban Environmental Monitoring and Actionable Sustainability Insights

Read article

Journal of Robotics and Control · Jan 27, 2026

With Kodithuwakku C.K., Arandara S.D., Karunarathne R.Y.D.

The study introduces the Intelligent EcoUrban Monitoring System (IEMS), an integrated AI-driven framework that combines IoT data, deep learning models, satellite imagery, and large language models to address key urban environmental challenges such as air pollution, noise, CO₂ emissions, and green space depletion. By unifying specialized components for air quality analysis, green space assessment, noise classification, and vehicle CO₂ estimation within a centralized data fusion pipeline, IEMS enables cross-domain intelligence and actionable insights for urban planners and policymakers. Experimental results demonstrate strong performance across multiple domains, highlighting the potential of AI-powered, multi-modal systems to support data-driven and sustainable urban development.
