Investigating Value of Information in Future Vehicular Communications
No full textThe next generations of vehicles are expected to be equipped with sophisticated sensors to support advanced automotive services. The large volume of data generated by such applications will likely put a strain on the vehicular communication technologies, which may be unable to guarantee the required quality of service. In this scenario, it is fundamental to assess the value of information (VoI) provided by each data source, to prioritize the transmissions that have greatest importance for the target applications. In this paper, we characterize VoI in future vehicular networks, and investigate efficient data dissemination methods to tackle capacity issues. Through a simulation study, we show how analytic hierarchy multicriteria decision processes can be exploited to determine the value of sensory observations as a function of space, time, and quality criteria
On the Feasibility of Integrating mmWave and IEEE 802.11p for V2V Communications
No full textRecently, the millimeter wave (mmWave) band has been investigated as a means to support the foreseen extreme data rate demands of emerging automotive applications, which go beyond the capabilities of existing technologies for vehicular communications. However, this potential is hindered by the severe isotropic path loss and the harsh propagation of high-frequency channels. Moreover, mmWave signals are typically directional, to benefit from beamforming gain, and require frequent realignment of the beams to maintain connectivity. These limitations are particularly challenging when considering vehicle-to-vehicle (V2V) transmissions, because of the highly mobile nature of the vehicular scenarios, and pose new challenges for proper vehicular communication design. In this paper, we conduct simulations to compare the performance of IEEE 802.11p and the mmWave technology to support V2V networking, aiming at providing insights on how both technologies can complement each other to meet the requirements of future automotive services. The results show that mmWave-based strategies support ultra-high transmission speeds, and IEEE 802.11p systems have the ability to guarantee reliable and robust communications
2012 IEEE Vehicular Networking Conference (VNC)
No full textOn behalf of the Organizing Committee, we would like to welcome you to the fourth edition of the IEEE Vehicular Networking Conference in Seoul, Korea. IEEE VNC is a unique conference sponsored by both IEEE Communications Society and Intelligent Transportation Systems Society. It brings together these distinct communities to facilitate learning and to benefit from each others’ experience in the respective fields. The organizing committee spent countless hours and worked diligently to make this conference possible and to put together a high-quality program. Producing a conference is always a team effort involving many volunteers, and we would like to thank the team that made IEEE VNC 2012 possible. In particular, we are greatly indebted to our Technical Program Committee co-chairs, Frank Kargl, Falko Dressler, Elmar Schoch, Jong-Moon Chung, and Giovanni Pau, as well as to their TPC members. The TPC co-chairs compiled a very interesting program with highly respected and distinguished invited speakers, and an excellent technical program. The conference received 78 submissions of which 25 were accepted for the main technical program. Ten submissions were accepted as work in progress for the poster session. Our TPC co-chairs collected over 250 reviews from reviewers from all parts of the world. We also would like to thank EDAS Conference Services, LLC, especially Alice Arapshian, for helping to produce the proceedings. The staff of IEEE, in particular Bruce Worthman and Deidre Zeigler, helped with handling the finances and with making logistics arrangements. We would like to thank them for their support. The organizing committee would like to acknowledge the generous financial support from Toyota InfoTechnology Center and KAIST IREC that helped us to keep the registration fees at a reasonable rate. Last but not least, we would like to take this opportunity to express our gratitude to the IEEE Communications Society and IEEE Intelligent Transportation Systems Society for their joint sponsorship of the conference. We hope that all attendees will enjoy the scientific and social program, as well as the beautiful city of Seoul. Welcome to IEEE VNC 2012!

Inter-Vehicular Communication -- Quo Vadis (Dagstuhl Seminar 13392)
No full text"Inter-Vehicular Communication -- Quo Vadis?". With this question in mind, leading experts in the field of vehicular networking met in Dagstuhl to discuss the current state of the art and, most importantly, the open challenges in R&D from both an scientific and an industry point of view. After more than a decade of research on vehicular networks, the experts very seriously asked the question whether all of the initial research issues had been solved so far.
It turned out that the perspective changed in the last few years, mainly thanks to the ongoing field operational tests in Europe and the U.S. The results point to new research directions and new challenges that need to be solved for a second generation of vehicular networking applications and protocols.
In four working groups, the experts studied these new challenges and derived recommendations that are also very helpful for the respective funding organizations
Inter-Vehicular Communication - From Edge Support to Vulnerable Road Users (Dagstuhl Seminar 21262)
No full textThis report documents the program and the outcomes of Dagstuhl Seminar 21262 "Inter-Vehicular Communication - From Edge Support to Vulnerable Road Users". Looking back at the last decade, one can observe enormous progress in the domain of vehicular networking. In this growing community, many ongoing activities focus on the design of communication protocols to support safety applications, intelligent navigation, and many others. We shifted the focus from basic networking principles to open challenges in edge computing support and, as a novel aspect, on how to integrate so called vulnerable road users (VRU) into the picture
Inter-Vehicular Communication Towards Cooperative Driving (Dagstuhl Seminar 18202)
No full textLooking back at the last decade, one can observe enormous progress in the domain of vehicular networking. In this growing community, many ongoing activities focus on the design of communication protocols to support safety applications, intelligent navigation, multi-player gaming and others.
This seminar shifted the focus from basic networking principles to networked control applications. We were particularly interested in eSafety applications and traffic efficiency applications that are thought to yield substantial benefits for the emerging "cooperative automated driving" domain.
The seminar brought together experts from several fields, including classical computer science (computer networking, simulation and modeling, operating system design), electrical engineering (digital signal processing, communication networks), and automated driving (mechanical engineering, image processing, control theory), to discuss the most challenging issues related to inter-vehicular communication and cooperative driving
