Data Dissemination in VANET Based Upon a Tree Topology
Wireless communication between vehicles, known as Vehicular Ad hoc NETwork (VANET), allows providing drivers with information like safety, efficiency, speed limit, any obstacle on road, road condition, traffic condition, commercial advertisement etc for convenience purpose. In vehicular technology a variety of sensors, radars and onboard computing systems which helped vehicles to information gathering and processing. Sensors can continuously monitor and detect the dangerous situation. They will broadcast the message to vehicles which are in their close vicinity. It is important to disseminate data from an information source to many destination vehicles in order to improve the quality of driving in terms of time, distance and safety.
