- Abstract
- In this paper, we introduce a Border Effect Problem and mitigation algorithm that can be applicable for Weighted Centroid Localization (WCL) based indoor positioning system. First, we generate virtual APs based on a terminal's initial estimated position by symmetrically flipping real APs position and their RSSI. Then we re-estimate terminal's position using both real APs and the selected virtual APs until it converges. We verified our proposed method mitigates the problem effectively through various simulation scenarios and their results.
