Abstract	The Internet of Things (IoT) proliferation has garnered widespread attention due to its versatile applications across manufacturing, commerce, and education industries. Within urban contexts, IoT plays a pivotal role in transforming cities into smart cities (SCs) by offering many applications and services. Nevertheless, these innovative urban solutions carry a significant environmental challenge: air pollution. In this context, the utilization of Deep Learning (DL) and Federated Learning (FL) techniques presents a solution for addressing forecasting challenges, particularly in scenarios involving volatile patterns of air contaminants (ACs) within vast and diverse datasets. The synergy of DL and FL has inspired us to harness the power of DL-based Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) models. These models form the foundation of our novel approach: Long Short-Term Gated Recurrent Unit (LSU). We employ the LSU method for accurate predictions of future air quality, while FL facilitates our model’s secure, decentralized, and distributed training. This study aims to achieve exact future air quality predictions by employing this innovative approach. To gauge the efficacy of the FeLLU framework, we conduct a comparative analysis against other machine learning models, utilizing a range of evaluation metrics. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
