Abstract
Welcome to the Second ACM International Workshop on Vehicular Ad Hoc Networks! Vehicular ad hoc networks show an enormous potential to increase traveler safety and comfort and can serve to improve the efficiency of the transportation infrastructure. The creation of high-performance, highly reliable, highly scalable, and secure VANET technologies, though, presents an extraordinary challenge to the wireless research community: a high degree of communication reliability is needed under unfavorable channel conditions. Clearly, the specificity of vehicular ad hoc networks in terms of mobility behavior and applications scenarios and requirements makes VANET research an exciting and demanding application- and purpose-driven sub-discipline of wireless networking.The opportunities for vehicular ad hoc networks are growing rapidly. In December 2003, the U.S. FCC approved 75 MHz of spectrum for Dedicated Short Range Communications (DSRC), and the resulting DSRC system is expected to be the first wide-scale VANET in North America. In Japan, two DSRC standards have been adopted (the ARIB STD-T75 in 2001, the ARIB STD-T88 in 2004), and Japanese auto manufactures are working with the Ministry of Land, Infrastructure, and Transportation in the third phase of an ambitious Advanced Safety Vehicle project. The European Union is funding, among others, the "Prevent" and "Global System for Telematics" Integrated Projects. The German Ministry of Education and Research has sponsored the "FleetNet" and "Network on Wheels" projects. Throughout the world, there are many national/international projects in government, industry, and academia devoted to VANETs.Our goal for this workshop is to discuss recent advances and to chart the way forward by bringing together diverse and exciting challenges, ideas and proposals of this very active VANET community.
