Cooperative Vehicle-Infrastructure System (CVIS)-European vision for vehicle-infrastructure systems
Paul Kompfner

Paul Kompfner
Paul Kompfner is Head of Development at ERTICO - ITS Europe, with over 14 years’ experience in co-ordination and management of European projects. He is currently coordinator of the CVIS (Cooperative Vehicle-Infrastructure Systems) integrated project that began in February 2006 within the “IST for eSafety” priority of the EU Sixth Framework Programme. He is also manager of the European Nomadic Device Forum and joint Chair of the eSafety Forum Working Group on “ICT for Clean & Efficient Mobility”.  An astrophysicist by training, he has led ERTICO projects on telematics system evaluation, traffic and travel information, road applications of satellite navigation, ITS planning for cities, ITS for public transport and driver safety & HMI. Before joining ERTICO Mr Kompfner was Principal Scientific Officer at the UK Transport Research Laboratory, where he led a section carrying out studies of accident risk, advanced driver training, company car use and transport systems operation.

End-to-End vs. Broadcast communications in VANET
Motivation statement: The implementation of end-to-end applications requires complicated network-level functionalities, such as point-to-point routing, and so on. This is especially difficult to achieve in a VANET environment, mainly due to the fast evolving network topology. On the other hand, broadcast-based applications are easier to handle at the network-level (e.g., no state information is stored at the nodes), but, of course, only a limited number of applications can be realized using only the one-to-all communication paradigm (or variations of this paradigm). The following question then arise: "Is there real need and are there applications of Ad-Hoc/Meshed-based networking approach for V2V communications, or is using only broadcast-based messaging enough?"

Mario Gerla
Mario Gerla, Professor, UCLA, Computer Science Dept.  Dr Gerla is one of the Pioneers of the ARPANET, with over 35 year of experience in Computer and Communications Networks. Dr. Gerla received his M.S. and Ph.D. degrees from UCLA in 1970 and 1973. He became IEEE Fellow in 2002. At UCLA, he was part of a small team that developed the early ARPANET protocols under the guidance of Prof. Leonard Kleinrock. He worked at Network Analysis Corporation, New York, from 1973 to 1976, transferring the ARPANET technology to several Government and Commercial Networks. He joined the Faculty of the Computer Science Department at UCLA in 1976, where he is now Professor. At UCLA he has designed and implemented some of the most popular and cited network protocols for ad hoc wireless networks including distributed clustering, multicast (ODMRP and CODE Cast) and transport (TCPW) under DARPA and NSF grants. He has lead the $12M, 6 year ONR MINUTEMAN project, designing the next generation scalable airborne Internet for tactical and homeland defense scenarios. He is now leading two advanced wireless network projects under ARMY and IBM funding. In the vehicular network scenario, with NSF and Industry sponsorship, he has led the development of peer to peer applications for safe navigation, urban sensing and location aware applications.

Dan Jiang
Daniel Jiang is a Research Principal at DaimlerChrysler Research, Engineering and Design North America Inc. His interest is centered on vehicular communication simulation and protocol design. He has led research on Mobile Internet and DriveBy InfoFueling and is currently focused on inter-vehicular safety communications. He received a B.S. in Computer Science from Rutgers University and was a doctoral student in Computer Science at UC Berkeley before joining DaimlerChrysler.

Martin Mauve
Martin Mauve received his Ph.D. degree in computer science from the University of Mannheim in 2000. He was an assistant professor at the University of Mannheim from 2000 to 2003. In August 2003 he joined the computer science department at the Heinrich-Heine University in Düsseldorf as a full professor, heading the chair for Computer Networks and Communication Systems. Since 2005 he is the head of the department for computer science at the Heinrich-Heine University. The current focus of his research is on mobile ad-hoc-networks and inter-vehicle communication.

Paolo Santi
Paolo Santi (moderator) received the Laura Degree and Ph.D. degree in computer science from the University of Pisa in 1994 and 2000, respectively. He has been researcher at the Istituto di Informatica e Telematica del CNR in Pisa, Italy, since 2001.  During his career, he visited Georgia Institute of Technology in 2001, and Carnegie Mellon University in 2003. His research interests include fault-tolerant computing in multiprocessor systems (during PhD studies), and, more recently, the investigation of fundamental properties of wireless multihop networks such as connectivity, lifetime, capacity, mobility modeling, and cooperation issues. He has contributed more than 35 papers and a book in the field of wireless ad hoc and sensor networking, and he has been involved in the organizational and technical program committee of several conferences in the field. He is a senior member of ACM and SIGMOBILE.
