Characterizing Urban V2V Link Communications

2020
After enhancing the communication performance at the MAC layer, in this chapter, we investigate the vehicular link layer performance, which is of paramount importance for reliable message exchanging. However, with limited literature available, there is a lack of understanding about how IEEE 802.11p based DSRC performs for V2V communications in urban ...

Channel Modeling for V2V Communications

2006 Third Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services, 2006
In this paper we describe results of a channel measurement campaign for modeling the V2V channel. After review of applications, potential frequency bands, and related work, we describe the measurements and results for delay spreads and multipath component fading amplitudes and correlations, made in multiple V2V environments.

MobSampling: V2V Communications for Traffic Density Estimation

2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011
We propose a fully-distributed approach to the on line estimation of vehicle traffic density. Our approach envisions vehicles communicating within a VANET and cooperating to collect density measurements through a uniform sampling of the road sections of interest.

Value-Anticipating V2V Communications for Cooperative Perception

2019 IEEE Intelligent Vehicles Symposium (IV), 2019
The growing penetration of on-board communication units is enabling intelligent vehicles to share their sensor data with cloud computing platforms as well as with other vehicles. Although this unlocks the possibility of a variety of emerging applications, the massive amount of data traffic in vehicular networks is expected to pose a big challenge in ...

Large-scale simulation of V2V environments

Proceedings of the 2008 ACM symposium on Applied computing, 2008
Providing vehicles with enhanced ability to communicate and exchange real-time data with neighboring vehicles opens up a variety of complex challenges that can only be met by combining different research fronts such as wireless communications, information processing, self-organization protocols and collaborative optimization.

Regularized ICI Cancellation in V2V Communications

Proceedings of the 16th International Conference on Engineering Applications of Neural Networks (INNS), 2015
In this work, we consider a V2V commnunication system operating over high relative speeds. In this scenario, the wireless channel is characterized by double selectivity, which results into intercarrier interference (ICI) at the receiver. To mitigate this effect, several equalization schemes have been proposed, which usually adopt a banded approximation

V2V Vehicle Safety Communication

2018
National Highway Traffic Safety Administration (NTHSA) has been interested in vehicle-to-vehicle (V2V) communication as the next step in addressing grooving rates of fatalities from vehicle related crashes. Today’s crash avoidance technologies depend on on-board sensors like camera and radar to provide awareness input to the safety applications.

Beamforming for Beaconing in V2V Communications

2019 IEEE XXVI International Conference on Electronics, Electrical Engineering and Computing (INTERCON), 2019
The following manuscript studies the benefits and weaknesses of using beamforming for beaconing in a vehicle to vehicle communication scenario following the specifications of the IEEE 802.11p standard. This is done through a simulation in which the performance of a uniform linear array of two isotropic antennas is compared to an isotropic antenna with ...

Contention window allocation scheme for V2V

2013 International Conference on Advanced Technologies for Communications (ATC 2013), 2013
This paper proposes a contention window (CW) allocation scheme for real-time emergency data for vehicle ad hoc networks. The proposed scheme reduces the probability of packet collisions with the vehicle-to-vehicle (V2V) protocol and provides bandwidth efficiency with a short delay for emergency sporadic data.

Coordinated Lane Changing Using V2V Communications

2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018
Lane changing behavior is one source of vehicle accidents on the road. Before changing to another lane, the driver needs to carefully assess the distances to surrounding vehicles. Vehicle-to-Vehicle (V2V) communications provide an opportunity to make lane changing decisions more safe and efficient. Within a vehicular network, all connected vehicles are
