Vehicular Ad hoc NETwork (VANET) is a new communications system for moving vehicles at high speed, which are equipped with wireless communication devices, together with additional wireless roadside units, enabling communications among nearby vehicles (vehicle-to-vehicle communication) as well as between vehicles and nearby fixed equipment (vehicle-to-infrastructure communication). Inter-vehicular communications aim to improve road traffic safety and provide multimedia services. VANET has become an important communication infrastructure for the Intelligent Transportation System (ITS). In this paper, the authors have studied the impact of vehicle mobility on the quality of service in VANET based on IEEE 1609.4.
