A Secure Cooperative Approach for Nonline-of-Sight Location Verification in VANET
O. Abumansoor,Azzedine Boukerche +1 more
TL;DR: A location verification protocol among cooperative neighboring vehicles to overcome an NLOS condition and secure the integrity of localization services for VANETs is presented and the simulation results showed improvement in neighborhood awareness under NLOS conditions.

Improved Robust TOA-Based Localization via NLOS Balancing Parameter Estimation
TL;DR: This paper introduces a “balancing parameter” related to the NLOS errors and forms a new robust weighted least squares (RWLS) problem with the source position and theNLOS balancing parameter as the estimation variables and leverages the S-Lemma to transform the RWLS problem into a non-convex optimization problem, which is relaxed into a convex semidefinite program.

Cooperative Volunteer Protocol to Detect Non-Line of Sight Nodes in Vehicular Ad hoc Networks
TL;DR: This work used the cooperative approach to develop the Co-operative Volunteer Protocol (CVP), which uses volunteer vehicles to disseminate the warning message from the source to the target vehicle experiencing an NLOS situation, and simulation results showed that the proposed protocol outperformed the GRANT protocol with regard to several metrics.

Geographical Information Enhanced Cooperative Localization in Vehicular Ad-Hoc Networks
TL;DR: Simulation results show that GIE-CL can handle the NLOS problem, and approach to its performance upper bound provided by the case with known NLOS/LOS link-type information.

Accurate 3D Localization Method for Public Safety Applications in Vehicular Ad-Hoc Networks
TL;DR: An improved subspace algorithm is proposed for time of arrival measurements in VANETs localization and it is robust for large measurement noise, as it is based on the eigen form of a scalar product and dimensionality.
