摘要：Vehicular ad hoc network (VANET) is developing technology in vehicular environment. It is sub groupof mobile ad hoc network (MANET). VANET is a technology that uses moving vehicles as nodes in network to createmobile network. In this paper, we present the concept of adaptive beacon broadcast and adaptive congestion control forsafety critical message in vehicular ad hoc network (VANET). When large number of vehicles transmits beacons at ahigher frequency then bandwidth can be exhausted very easily, so number of packet collision occurs. To avoid thissituation adaptive beacon broadcast and adaptive congestion control concept is present in this paper. Adaptive BeaconBroadcast has dynamically partition the beacon interval to enhance the efficiency and fairness of using multiple datarates for beacons. Performance of the proposed system is evaluated by delay and throughput.
