Inter-vehicle communications will play an important role in future cars and traffic management in general. Many different services have been proposed in the literature using Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. These services include safety applications like collision warning, up-to-date traffic information, active navigation, and also infotainment. Efficient data dissemination in Vehicular NETworks (VANET) is of particular interest for both safety and infotainment services. In case of infotainment services, which are the object of the authors' paper, data dissemination is used to extend the radio coverage area of a Road Side Unit (RSU) to reach all users that can be interested in a given service.
