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. Using the terms Vehicular Ad-hoc Networks (VANETs), Inter-Vehicle Communication (IVC), Car-2-X (C2X), or Vehicle-2-X (V2X), many applications – as interesting as challenging – have been envisioned and (at least) partially realized. Very large projects have been initiated to validate the theoretic work in field tests and protocols are being standardized. With the increasing interest from industry, security and privacy have also become crucial aspects in the stage of protocol design in order to support a smooth and carefully planned roll-out. We are now entering an era that might change the game in road traffic management. Many car makers already supply their recent brands with cellular and WiFi modems, some also adding vehicular WLAN (DSRC, ITS-G5) and C-V2X technologies.

With this latest installment of the “Inter-Vehicular Communication”- Dagstuhl Seminar series, we intend to shift 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. Edge computing is currently becoming one of the core building blocks of cellular networks, including 5G, and it is necessary to study how to integrate ICT components of moving systems. The trade-offs of computation distribution, system aspects, and the impact on end-to-end latency are still unanswered. Also, vehicular networking and cooperative driving focuses almost exclusively on cars but leaves out communication and coordination with, for example, pedestrians and bicyclists. For example, many of the existing communication solutions for this scenario were designed without having battery constraints in mind. In the meantime, some early research has been initiated on this topic and initial projects report very interesting results on safety features for VRUs. Building upon the great success of the previous Dagstuhl Seminars – as documented, e.g., with results published in widely visible magazine articles [1, 2, 3] – with this follow-up seminar, we aim to again bring together experts from all these fields from both academia and industry.

Following the tradition of Dagstuhl, the seminar will focus on lively interactions and discussions stimulated by two or three keynote talks. We plan organizing these discussions in the form of working groups on main topics of the seminar including virtualized edge computing, pedestrian and bicyclist interaction, and resilience of the underlying communication fabric.
