Car-to-Car Communication

Car-to-car communication aims at increased driving comfort and safety. Moreover, it changes the role of vehicles from mere transportation means to "smart objects". Despite many R&D activities in the last years, this technology still poses multiple challenges on the wireless transmission and network protocols. Aspects like efficient message dissemination, network scalability, and information security mechanisms are still major research areas in the area of vehicular ad hoc networks. In this paper we present the potential of future car-to-car
and car-to-environment communication systems, introduce the major research challenges in this field, and provide a selection of current research results.
