Cluster Head Selection for CCB-MAC Protocol by Implementing High Priority Algorithm in VANET

VANET is a field of technology through which road accidents can be reduced which leads to the reduction of the death rate. For this purpose, different protocols were proposed to improve the VANET network for safety messages, priority messages, and application based schemes, but MAC ( Medium Access Control) is a branch where fewer researchers explored the literature. We proposed a VANET lane model for reducing the delay of the packets using high priority algorithm for cluster selection to transmit the safety messages rapidly. Therefore, cooperative clustering based MAC is one of the fields for broadcasting the safety messages to reduce the delay of transmission at the time of emergency. Cooperation using the cluster member node as a cooperation node for transmission of safety messages from source to destination without affecting the overall transmission of the network.
