Internet of Vehicles (IoV) technology has been rapidly advancing, making intelligent transportation systems the future trend. This research revolves around building efficient and secure vehicular networks using data processing mechanisms backed by machine learning and information security. However, noise and incremental data present challenges to vehicular network development. This study proposes two novel federated learning frameworks, namely the Outlier Detection and Exponential Smoothing Federated Learning (OES-FED) and Federated Learning Framework Based on Incremental Weighting and Diversity Selection for IoV (FED-IW&DS), to overcome the above problems. The OES-FED framework leveraged anomaly detection and exponential smoothing to filter noise data, thus, improving model robustness and enhancing communication efficiency. In terms of accuracy, it outperformed the existing Federated Learning-Average (FED-AVG) and FED-SGD models on three datasets by 44.46% and 2.36%, respectively. Fur.....
