Description

technical field

[0001] The invention belongs to the technical field of Internet of Vehicles communication, and relates to a routing method for vehicle node communication, in particular to a routing method for Internet of Vehicles based on the cognitive interaction degree of nodes. Background technique

[0002] With the rapid development of Internet of Vehicles technology in recent years, urban traffic interconnection is gradually operating in an intelligent and collaborative manner. However, similar to other open dynamic networks, due to the dynamic and changeable topology of the urban traffic network, short vehicle interaction time, and uneven distribution of vehicle nodes, there are often interruptions in network connection and data communication, and it is difficult for message data to pass through suitable channels. Phenomena such as the relay reaches the destination node.

[0003] The delay tolerant network (Delay Tolerant Network, DTN) has the characteristics of time-...
