Location-aware technologies will revolutionize many aspects of commercial, public service,
and military sectors, and are expected to spawn numerous unforeseen applications. A new …

Position estimation of wireless devices has many applications in short-range networks. Ultra-
wideband (UWB) signals provide accurate positioning capabilities that can be harnessed in …

In this paper, we propose a linear-programming (LP) approach to the problem of nonline-of-
sight (NLOS) mitigation in ad hoc ultrawideband wireless networks. The locations of …

Nonline-of-sight (NLOS) propagation is one of the challenges in radio positioning.
Significant attention has been drawn to the mitigation of the NLOS effect in recent years. This …

In this paper, a technique for modeling propagation of ultrawideband (UWB) signals in
indoor or outdoor environments is proposed, supporting the design of a positioning systems …

In this paper, we describe a global distributed solution that enables the simultaneous
performance of time synchronization and positioning in ultra-wideband (UWB) ad hoc …

Non Line of Sight (NLOS) channels are one of the major drawbacks for accurate ranging
and localization with Ultra-Wideband (UWB) technology. Whereas several proposals exist to …

In this article we study the problem of localizing a fleet of vehicles in an indoor environment
using ultra-wideband (UWB) signals. This is typically done by placing a number of UWB …

Nonline-of-sight (NLOS) conditions pose a major challenge to radio positioning. In this
paper, a constrained-optimization-based location algorithm is proposed to jointly estimate …

Ultra-wide band (UWB) sensors are innovative devices constructed for efficient wireless
communications that have recently being used for vehicle localization in indoor …
