The proposed method is effective, as shown by a significant reduction in mean error and narrowing of standard deviation and maximum values. The 95th percentile value has been enhanced, effectively mitigating the impact of extreme outliers. With improve of ranging performance, the standard deviation and 95th percentile of the positioning error improved in suitable RSSI threshold. values.
