Road Safety Based Model By Broadcasting Communication in VANET’s

To detect the position forging attacks in vehicular ad hoc networks (VANETs) and to improve vehicle passenger safety by means of inter vehicle communication. In the existing system, it presents a model for the performance evaluation of safety message dissemination in VANETs with two classes. In particular, considering the IEEE 802.11 broadcast protocol and 2D Markov modelling. Then the result is used to drive the average dissemination delay of highpriority messages in the presence of the low –priority traffic in the network. In the proposed system, to introduce multiple RSU from position forging attacks and combination of position and ID forging attacks. It provides primary key and RTS/CTS based on AMBA for each vehicle for security purpose. The network generates the secret key (random key) for each vehicle it secures on On-Board Unit (OBU). The Block forwarding process is used for acknowledgement. Vehicle will give the request to RSU and get the needed response from network while moving one network to another network.
