Soumaya Zirari, Philippe Canalda, Francois Spies
TL;DR
This paper introduces a new Dilution of Precision (DOP) metric for Wi-Fi-based positioning that considers geometric and signal strength factors to improve accuracy assessment.
Contribution
It proposes the Geometric and Signal Strength DOP as a novel coefficient for evaluating Wi-Fi positioning accuracy.
Findings
The DOP metric effectively quantifies positioning accuracy.
Incorporating signal strength improves DOP reliability.
The method enhances understanding of Wi-Fi positioning limitations.
Abstract
The democratization of wireless networks combined to the emergence of mobile devices increasingly autonomous and efficient lead to new services. Positioning services become overcrowded. Accuracy is the main quality criteria in positioning. But to better appreciate this one a coefficient is needed. In this paper we present Geometric and Signal Strength Dilution of Precision (DOP) for positioning systems based on Wi-Fi and Signal Strength measurements.
