摘要：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 whic h 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. In order to avoid the broadcasting storm problem in wireless networks, we present BODYF protocol with time constraint which relay on the tree –based topology .the behavior of this protocol does not depend upon any parameter which makes it challenging and suitable for highly fluctuating network like VANETs. With the help of this we can calculate whether message is forwarded or not with in time limit, so that limited available bandwidth can be efficiently utilized. Se ctions II present the different type of data disse mination technique; Section III data aggregation framework; Section IV proposed BODYF protocol. Finally we conclude the paper and give some perception to our work in Section V
