SimDeep: Federated 3D Indoor Localization via Similarity-Aware Aggregation
This addresses indoor localization for location-based services, with incremental improvements in handling non-IID data in federated learning.
The paper tackles the challenge of indoor localization in real-world scenarios with non-IID data and device heterogeneity by proposing SimDeep, a federated learning framework that uses similarity-aware aggregation, achieving 92.89% accuracy and outperforming traditional methods.
Indoor localization plays a pivotal role in supporting a wide array of location-based services, including navigation, security, and context-aware computing within intricate indoor environments. Despite considerable advancements, deploying indoor localization systems in real-world scenarios remains challenging, largely because of non-independent and identically distributed (non-IID) data and device heterogeneity. In response, we propose SimDeep, a novel Federated Learning (FL) framework explicitly crafted to overcome these obstacles and effectively manage device heterogeneity. SimDeep incorporates a Similarity Aggregation Strategy, which aggregates client model updates based on data similarity, significantly alleviating the issues posed by non-IID data. Our experimental evaluations indicate that SimDeep achieves an impressive accuracy of 92.89%, surpassing traditional federated and centralized techniques, thus underscoring its viability for real-world deployment.
