An analysis of the error characteristics of two time of arrival localization techniques

open access: yes, 2010
Accurate local positioning systems usually use a network of anchor nodes at known locations to track mobile nodes based on the measurement of the time of arrival (TOA) at anchor nodes of beacon signals transmitted by the mobile nodes.

Novel sensor location scheme using time-of-arrival estimates

open access: yes, 2012
This study proposes a novel scheme for locating an asynchronous sensor with synchronised beacons using time-of-arrival (TOA) estimates. In this scheme, a reference beacon initiates the localisation by emitting a ranging signal, and the sensor position is

Synchronization of perturbed Genesio-Tesi chaotic systems via a new finite-time control

open access: yes, 2018
This paper investigates the synchronization problem for perturbed Genesio-Tesi chaotic system. Based on Lyapnov stability theory, a new finite-time control method is proposed to ensure that the synchronization takes place in finite time.
