A Concave-Convex Procedure for TDOA Based Positioning [PDF]
This letter investigates the time-difference-of-arrival based positioning problem in wireless sensor networks. We consider the least-mean absolute, i.e., the \ell_1 norm, minimization of the residual errors and formulate the positioning problem as a difference of convex functions (DC) programming.

A method for localization TDOA estimation based on signal‐level fusion and analysis
Passive localization using time difference of arrival (TDOA) is one of the common methods for radiated source target localization, and its localization performance depends on the accuracy of TDOA estimation. In many localization scenarios, the signals of

This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

High-Precision Time Difference of Arrival Estimation Method Based on Phase Measurement
In unmanned aerial vehicle (UAV)-based time difference of arrival (TDOA) positioning technique, baselines are limited due to communication constraints. In this case, the accuracy is highly sensitive to the TDOA measurements’ error. This article primarily

TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs
This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

Sparsity-aware TDOA localization of multiple sources
The problem of source localization from time-difference-of-arrival (TDOA) measurements is in general a non-convex and complex problem due to its hyperbolic nature. This problem becomes even more complicated for the case of multi-source localization where
