ToA-TS: Time of arrival based joint time synchronization and tracking for mobile underwater systems [PDF]
Ad Hoc Networks, 2015 Time synchronization and localization are key requirements for distributed underwater systems consisting of numerous low-cost submersibles. In these systems, submersibles are highly resource constrained and typically have limited acoustic communication capability.

Self-Calibration for the Time-of-Arrival Positioning
IEEE Access, 2020 Self-calibration of time-of-arrival positioning systems is made difficult by the non-linearity of the relevant set of equations. This work applies dimension lifting to this problem.

A Fractional Programming Method for Target Localization in Asynchronous Networks
IEEE Access, 2018 In this paper, we address the target device localization problem in the asynchronous networks. For the purpose of saving power resources, the target device is not synchronized with the anchor nodes, but is only required to listen to the signals ...

A New Time-Based Algorithm for Positioning Mobile Terminals in Wireless Networks
EURASIP Journal on Advances in Signal Processing, 2008 This paper presents a positioning algorithm, named time of arrival to time difference of arrival (TOAD), which computes time-difference-of-arrival (TDOA) measurements from the messages that time-of-arrival (TOA) stations in sight exchange while their ...
