E-SALDAT: Efficient Single-Anchor Localization of Dual-Antenna Tags
Accurate localization is required to enable location awareness of devices in many IoT applications. Current state-of-the-art ultra-wideband solutions make use of ranging measurements in a multi-anchor setup. In this paper, we propose a novel single-anchor scheme (E-SALDAT): an improvement of the Dual Wireless Radio Localization (DWRL). While four ranging measurements were previously required for semi-localization (usually, the first step towards definite localization/rigid-localization), E-SALDAT allows for semi-localization with only two ranging measurements. This results in a significant improvement of overall power efficiency and localization ratio. We present a comparison of the proposed localization scheme E-SALDAT to its predecessors I-DWRL and DWRL. The comparison was performed based on simulations. Our results suggest that E-SALDAT, on average, can achieve double the localization ratio of I-DWRL with just 23% more messages.
