Abstract: Highlights•Novel RSSI data processing pipeline enhances WiFi indoor localization accuracy.•Addresses stale data issue by prioritizing last-seen timestamps over local for fresher RSSI data.•Introduces AP filling approach to maintain localization accuracy during access point unavailability.•Proposes Wasserstein distance-based AP selection strategy for optimized system performance.
