Extensive research activities and field operation tests on V2I and V2V communication have been carried out for more than a decade. However, there are still some unsolved issues for successful and sustainable deployment of cooperative systems based on vehicular communication. Open challenges for a deployment of cooperative applications with high reliability and user acceptance include: minimal performance requirements on positioning accuracy and wireless performance to ensure interoperability, congestion control and adaptive data aggregation for reliable communications, life cycle management and security & privacy issues to ensure the user acceptance and protect the investments.

Advanced cooperative applications require a deployment of vehicles equipped with V2V communication at high penetration rate. However, presently only applications which do not require time-critical communication and high penetration rate can be deployed based on cellular communication (3G/4G). But how can we bridge the penetration rate gap and introduce also time-critical applications step-by-step? One promising solution might be selective infrastructure support: Roadside units with 802.11p technology, initially deployed on accident prone spots, extend the coverage and enable time-critical applications for every equipped vehicle from the start of deployment. It is also possible to reduce the latency of cellular communication by moving the applications closer to the road. Thereby, applications reside directly on mobile base stations and do not need additional connectivity to the core network.

A second approach is hybrid communication providing seamless connectivity. Vehicles equipped with multiple wireless technologies are able to decide which interface to use based on the availability of the technology, its current coverage, or requirements of the applications. With this approach, all traffic participants including pedestrians and vulnerable users can be integrated seamlessly into one common ITS system. Hence, the overall question is: What will bring us closest to the goal of seamless V2X connectivity? Is the full V2V penetration rate the ultimate solution? Do we have to wait for the next evolution of cellular communication technologies? Or will the hybrid concept with seamless connectivity and evolutionary integration of other technologies pave the way?


Mr. Josef Jiru heads the Automotive Connectivity group at the Fraunhofer Institute for Embedded Systems and Communication Technologies ESK which he joined in 2006.

He has been in charge of several projects in the field of Vehicle-to-X Communication and Advanced Driver Assistance Systems based on communication. His research activities focus on efficient networking concepts and adaptive data aggregation in vehicular networks.

Josef Jiru studied electrical engineering and information technology at the Technical University Munich and graduated as "Diplom-Ingenieur".
