Channel Characterization for Vehicle-to-Infrastructure Communications at the Terahertz Band

2020 IEEE International Conference on Communications Workshops (ICC Workshops), 2020
Although the vehicular communications began from the era of the Long Term Evolution (LTE), the strict requirements of the vehicular safety and advanced applications force the academic and industrial communities to continue the topic on the next-generation vehicular communications.

Geolocation-based Sector Selection for Vehicle-to-Infrastructure 802.11ad Communication

2021 19th Mediterranean Communication and Computer Networking Conference (MedComNet), 2021
To improve range, 802.11ad uses directional communication, the first step of which is to choose the best antenna configuration, or sector. We studied the sector selection behavior of Commercial Off-The-Shelf (COTS) 802.11ad equipment in an experimental Vehicle-to-Infrastructure (V2I) communication scenario.

Measurement and evaluation of communication parameters on a Vehicle-to-infrastructure communication test site

2014 International Conference on Connected Vehicles and Expo (ICCVE), 2014
The German Aerospace Center (DLR) operates a test field for cooperative ITS systems using Vehicle-to-X communication. Since a long-term operation is planned several periodic measurements and test drives have to be taken and the measurement data has to be evaluated.

On roadside unit antenna measurements for vehicle-to-infrastructure communications

2012 IEEE 23rd International Symposium on Personal, Indoor and Mobile Radio Communications - (PIMRC), 2012
In this paper, we discuss and analyze results from real-world vehicle-to-infrastructure measurements in an IEEE 802.11p-based vehicular ad hoc network. For our experiments we have used six roadside units (RSUs) mounted on highway gantries equipped with five different antenna types.

Signal-to-noise ratio modeling for vehicle-to-infrastructure communications

2014 IEEE 6th International Symposium on Wireless Vehicular Communications (WiVeC 2014), 2014
In this contribution we propose an extension to the range-dependent modified Gilbert model introduced in [1]. With the proposed extension, the model can be used to generate realistic vehicle-to-infrastructure signal-to-noise ratio (SNR) traces along with the corresponding error patterns.

Urban vehicle-to-infrastructure wireless communications range evaluation

2012 15th International IEEE Conference on Intelligent Transportation Systems, 2012
We consider the problem of information propagation for traffic management applications of Intelligent Transportation Systems in urban areas. In this paper is described a system for measurement of communication range of vehicular wireless communications, method for processing and interpreting the measured data and the initial results.

Machine learning based optimization for vehicle-to-infrastructure communications

Future Generation Computer Systems, 2019
In this paper, we study wireless communications in vehicle-to-infrastructure communications. In certain situations, multiple vehicles within a local range need to exchange information via common roadside infrastructure. Example scenarios include busy intersections, and a driver with the knowledge of information from other vehicles can make safer ...

Cooperative Relay Selection and Forwarding in Vehicle-to-Infrastructure Communications

2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017
The wireless sensors deployed at the highway can ensure the safety of the traveling vehicles. However, the ribbon deployed wireless sensor network in the roadside infrastructure can easily to generate energy hole. Cooperative communication between sensors and vehicles is an effective way to improve this situation and reduce the energy consumption of ...
