Welcome to VTP 2012
Vehicular ad hoc networks (VANETs) use vehicle-to-vehicle as well as vehicle-to-infrastructure communication, for providing drivers with novel services, such as collision avoidance, realtime traffic information, high-speed toll collection and infotainment. The emergence of these networks has raised novel research challenges that are different from regular ad hoc networks. These challenges are induced by the high speed of the vehicles, which leads to specific mobility and connectivity patterns.
In order to provide efficient, reliable and secure services, dedicated solutions are required. It includes new communications standards (e.g. 802.11p) and information dissemination algorithms (e.g. geocasting). Developing applications and protocols for such an environment creates unique security and trust-related challenges. It also requires experimental testbeds and simulation tools for their performance evaluation.
Prototyping and testbeds allow to obtain performance measures under real-word conditions such as realistic signal propagation and vehicles' mobility patterns. Simulation — complementary to costly and often limited in scale testbed experiments — is one of the most often used methods for performance evaluation. However, it requires the development of realistic models for the signals' physical characteristics and mobility at a macroscopic as well as a microscopic level.
The target audience of this workshop is represented by researchers from the mobile ad hoc network community working in the VANET domain.
