Cluster based emergency message broadcasting technique for vehicular ad hoc network

摘要: Broadcasting is one of the major emergency services Vehicular ad hoc network, since number vehicles increases every day. Because high density vehicles, it necessary to broadcast messages all avoid traffic jam and vehicle accidents. Reliable broadcasting in self-organizing Ad networks a promising research field. In this paper cluster based message algorithm proposed. regard we have proposed architecture for dissemination collision avoidance VANET. paper, first formation done such way that avoids any kind collision. Once head selected takes responsibility intra management interference between clusters. To increase reliability during two MAC layer broadcasts protocol used. This assures delivered on time without hazards. The model simulated DSDV, AODV, DSR protocols with standards 802.11 802.11p SHWM, Manhattan freeway mobility models.
