Car-to-car communication aims an 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 the European Union some research projects look into the potential of reducing road fatalities under the eSafety initiative (e.g. GST, PreVent). The same is true in other countries like the USA or Japan. Car-to-car communication (C2CC), often referred to as vehicular ad hoc networks (VAMOETs), enables many new services for vehicles and creates numerous opportunities for safety improvements. Communication between vehicles can e.g. be used to realize driver support and active safety services like collision warning, up-to-date traffic and weather information or active navigation systems. However, besides enabling new services VANETs pose many challenges on technology, protocols, and security which increase the need for research in this field. 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.
