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
