A Cluster Routing Algorithm Based on Vehicle Social Information for VANET

In recent years, with the gradual rise and improvement of autonomous driving technology, research on vehicle ad hoc network (VANET) has gradually been paid attention by researchers. In VANET, the vehicle nodes are networked through a routing protocol and communicate with each other with the established routing. However, the high-speed mobility of vehicle nodes will cause rapid changes in the topology of the network, which can increase the information transmission delay. And as the number of vehicles increases, the probability of information transmission collision in the network will also increase. When the delay and collision reach a certain level, it will cause the loss of information. In order to solve these problems, this paper proposes a cluster routing algorithm based on vehicle social information. The communication source node and the destination node will communicate with each other through these cluster heads. This algorithm is superior to the traditional routing algorithm in terms of VANET communication performance.
