Vehicular ad hoc network (VANET) is an example of mobile applications developed recently of Intelligent Transportation Systems (ITS). This network comprises mainly of vehicles and road infrastructure, connected each to other for exchanging traffic data (V2V communication and V2I communication). It allows sharing data between vehicles in a collaborative way. In this thesis, we are particularly interested in road safety applications, designed for the exchange of information on road traffic. This kind of applications have strict Quality of Service (QoS) requirements, as data must be delivered thoroughly and without any delays. In this context, data routing will face several issues caused by rapidly dynamic topology, which characterizes VANETs, intermittent connectivity, and high mobility of vehicle nodes. Indeed, the problem of data dissemination in this field is non-trivial, and several research challenges must be solved in order to provide an efficient support for road safety applications. Specifically, we will address the problem of studying data dissemination’s protocols and mechanisms in the new situation caused by the emergency of advanced comfort and driving assistance technologies in VANETs.
