The intra cluster routing protocol designed in this paper is based on the trust model of vehicle nodes. The trust model is mainly composed of the reliability of vehicle nodes and other attribute factors of vehicle nodes. The cloud data center uses principal component analysis to calculate the trust value. The attributes of the vehicle nodes in the cluster are forwarded to the cluster head along with the Hello message packet. The cluster head forms an attribute list and sends it to the cloud data center, which calculates the trust value. When there are multiple paths to choose, the vehicle nodes in the cluster take the trust value of each node on the path as an important basis for path selection, forming the routing process in the cluster. By adding trust computation, reliable data transmission between vehicle nodes can be guaranteed. The experimental results show that the intra cluster routing protocol designed by the trust model in this scheme is effective and feasible, and the maximum speed of vehicle nodes has an impact on the performance of the routing algorithm.
