This paper presents UnSpoof, a UWB localization system that can detect and localize
distance-spoofing tags with several collaborative passively-receiving anchors. We propose …

Today, location and proximity information are key to a number of emerging applications.
With the advent of the Internet of Things and autonomous cyber-physical systems, the …

A myriad of IoT applications, ranging from tracking assets in hospitals, logistics, and
construction industries to indoor tracking in large indoor spaces, demand centimeter …

Recently, we introduced PolyPoint, a high-fidelity RF-based indoor localization system that
achieves 28 cm accuracy indoors and tracks a fast-moving quadcopter with only 56 cm …

We present a trustworthiness score for double-sided two-way ranging on ultra-wideband
devices. It serves as quantitative measure for assessing the reliability and security aspects of …

Most localization systems rely on measurements gathered from signals emitted by stations
whose position is assumed known as ground truth, namely anchors. As demonstrated by a …

Precise localization encompassing diverse indoor spaces is the key to immersive interaction
services. In practice, indoor localization often undergoes blind spots as RF is easily blocked …

Understanding the location of ultra-wideband (UWB) tag-attached objects and people in the
real world is vital to enabling a smooth cyber-physical transition. However, most UWB …

Setting up indoor localization systems is often excessively time-consuming and labor-
intensive, because of the high amount of anchors to be carefully deployed or the …
