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.

Persistent Traffic Measurement Through Vehicle-to-Infrastructure Communications
2017 IEEE 37th International Conference on Distributed Computing Systems (ICDCS), 2017Measuring point traffic volume and point-to-point traffic volume in a road system has important applications in transportation engineering. The connected vehicle technologies integrate wireless communications and computers into transportation systems, allowing wireless data exchanges between vehicles and road-side equipment, and enabling large-scale ...

On roadside unit antenna measurements for vehicle-to-infrastructure communications
2012 IEEE 23rd International Symposium on Personal, Indoor and Mobile Radio Communications - (PIMRC), 2012In 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), 2014In 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.

V2V2I: Extended inter-vehicles to infrastructure communication paradigm
Global Information Infrastructure Symposium - GIIS 2013, 2013We consider the problem of providing ubiquitous IPv6 Internet connectivity to vehicles compliant with IEEE WAVE standard. In particular, we take advantage of two realistic technology trends. On the one hand, IEEE 802.11p interfaces should be mandatory on the On-Board Units (OBUs) but the Road-Side Units (RSUs) deployment will not be immediate.

Machine learning based optimization for vehicle-to-infrastructure communications
Future Generation Computer Systems, 2019In 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 ...

IEEE 802.11p vehicle to infrastructure communications in urban environments
IEEE Communications Magazine, 2012The future exploitation of cooperative vehicular services in urban environments, generally characterized by challenging propagation conditions, will require an efficient deployment of roadside units. This article presents the results of an extensive field testing campaign aimed at analyzing the impact of urban characteristics, RSU deployment conditions,

An integrated architecture for multi-homed vehicle-to-infrastructure communications
2012 IEEE Network Operations and Management Symposium, 2012We develop an intelligent distributed quality-of-service (QoS) control scheme which inter-operates between mobile routers, managing vehicular networks mobility, and road communication gateways (RCGs). This scheme manages vehicle-to-infrastructure (V2I) communications by enabling multi-homed vehicular networks to evenly distribute traffic among egress ...

VIPER: A vehicle-to-infrastructure communication privacy enforcement protocol
2007 IEEE Internatonal Conference on Mobile Adhoc and Sensor Systems, 2007Privacy-related issues are crucial for the wide diffusion of Vehicular Communications (VC). In particular, traffic analysis is one of the subtler threats to privacy in VC. In this paper we first briefly review current work in literature addressing privacy issues.
