Vehicular AdHoc Networks or VANETs are emerging as a promising technology for providing safety and comfort applications for vehicular transportation. VANETs are receiving growing attention from the research community and from the transportation industry because of their great potential to improve traffic safety on roads. In existing system the IEEE 802.11 broadcasting mode, considers no request-to-send/clearto- send (RTS/CTS) handshaking process, because all of the nodes are within the range of a sending node and that node will be act as the recipients. Thus, the size of the potential hidden node activity‟s area is dramatically larger than the 802.11 unicast mode, which makes the communications more unreliable. In this work, the main objective is to show the hidden terminal problem, packet leakage and multi message broadcasting and the delay time has been reduced. To reduce the delay and overcome the single message broadcasting problem in the existing system, the probabilistic data structure is proposed. To address the degree of compatibility of the protocol Dedicate Short Range Communication (DSRC) method is used. The network operation mode is introduced for Dedicate Short Range Communication standardization. Thus the result of this work is to reduce the low priority messages and also determine the good tradeoff between network parameters.
