TL;DR: This article proposes the novel design of a vehicular mmWave system combining the advantages of the Internet of Things and cloud computing, which supports vehicles sharing multi-gigabit data about the surrounding environment and recognizing objects via the cloud in real time.
Abstract: Autonomous vehicles are a rising technology in the near future to provide a safe and efficient transportation experience. Vehicular communication systems are indispensable components in autonomous vehicles to share road conditions in a wireless manner. With the exponential increase of traffic data, conventional wireless technologies preliminarily show their incompetence because of limited bandwidth. This article explores the capability of millimeter-wave communications for autonomous vehicles. As the next-generation wireless technology, mmWave is advanced in its multi-gigabit transmittability and beamforming technique. Based on these features, we propose the novel design of a vehicular mmWave system combining the advantages of the Internet of Things and cloud computing. This mmWave system supports vehicles sharing multi-gigabit data about the surrounding environment and recognizing objects via the cloud in real time. Therefore, autonomous vehicles are able to determine the optimal driving strategy instantaneously.

TL;DR: In this article, location information obtained and continuously updated from vehicular-based cellular phones is collected, processed and used as a basis for input to Intelligent Transportation Systems, in particular to Real Time Urban Traffic Guidance for Vehicular Congestion and Intelligent Traffic Control Systems.
Abstract: Location information obtained and continuously updated from vehicular-based cellular phones is collected, processed and used as a basis for input to Intelligent Transportation Systems, in particular to Real Time Urban Traffic Guidance for Vehicular Congestion and Intelligent Traffic Control Systems. Location information that forms the basis of the present invention is obtainable from wireless location systems such as GSM in Europe, CDMA in the USA, or PDC in Japan, and depends on supporting technologies, which are in the process of perpetual improvement. Relying on cellular networks location system capabilities to provide moderately reliable position information, the records of vehicle phones coordinates, timing, etc., are collected, updated and stored in the Traffic Service Center database. Those records together with digital maps are fed into mathematical models and algorithms that construct lists of vehicles traveling on various road sections, traffic loads at particular road sections, real time travel times along all road sections resulting from traffic congestion in particular areas, turning loads for signal intersections, and other key parameters necessary for real time functioning of Intelligent Transportation Systems, in particular of Intelligent Traffic Control Systems, Route Guidance Systems, etc.

01 Dec 2010TL;DR: This work performs experimental measurements in order to collect received signal power and packet delivery ratio information in a multitude of relevant scenarios: parking lot, highway, suburban and urban canyon, and shows that obstructing vehicles cause significant impact on the channel quality.
Abstract: Channel models for vehicular networks typically disregard the effect of vehicles as physical obstructions for the wireless signal. We aim to clarify the validity of this simplification by quantifying the impact of obstructions through a series of wireless experiments. Using two cars equipped with Dedicated Short Range Communications (DSRC) hardware designed for vehicular use, we perform experimental measurements in order to collect received signal power and packet delivery ratio information in a multitude of relevant scenarios: parking lot, highway, suburban and urban canyon. Upon separating the data into line of sight (LOS) and non-line of sight (NLOS) categories, our results show that obstructing vehicles cause significant impact on the channel quality. A single obstacle can cause a drop of over 20 dB in received signal strength when two cars communicate at a distance of 10 m. At longer distances, NLOS conditions affect the usable communication range, effectively halving the distance at which communication can be achieved with 90% chance of success. The presented results motivate the inclusion of vehicles in the radio propagation models used for VANET simulation in order to increase the level of realism.

Abstract: Among civilian communication systems, vehicular networks emerge as one of the most convincing and yet most challenging instantiations of the mobile ad hoc networking technology. Towards the deployment of vehicular communication systems, security and privacy are critical factors and significant challenges to be met. Thanks to the substantial research efforts carried out by the community so far, we make the following contributions in this paper: we outline security requirements for vehicular communication systems, we provide models for the system and the communication, as well as models for the adversaries, and propose a set of design principles for future security and privacy solutions for vehicular communication systems.

TL;DR: The vehicular information transfer protocol (VITP), a location- aware, application-layer, communication protocol designed to support a distributed service infrastructure over vehicular ad- hoc networks, is introduced and the results demonstrate the viability and effectiveness of VITP in providing location-aware services over VANETs.
Abstract: Recent advances in wireless inter-vehicle communication systems enable the establishment of vehicular ad-hoc networks (VANET) and create significant opportunities for the deployment of a wide variety of applications and services to vehicles. In this work, we investigate the problem of developing services that can provide car drivers with time-sensitive information about traffic conditions and roadside facilities. We introduce the vehicular information transfer protocol (VITP), a location- aware, application-layer, communication protocol designed to support a distributed service infrastructure over vehicular ad- hoc networks. We describe the key design concepts of the VITP protocol and infrastructure. We provide an extensive simulation study of VITP performance on large-scale vehicular networks under realistic highway and city traffic conditions. Our results demonstrate the viability and effectiveness of VITP in providing location-aware services over VANETs.
