Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0037] The invention integrates the idea of ​​the prophet protocol, avoids the problem of "cold start" of the system, fully considers the fact that different vehicle nodes in the real urban traffic road network have different distribution characteristics and mobility characteristics, and pays attention to whether the next hop can be efficiently and accurately used as a relay The message is delivered to the target node, and incentives are given to the nodes participating in the interaction and relay, so as to activate network interaction and promote information forwarding. The specific steps include: 1. Node connection establishment 2. Relay node screening 3. Message delivery completed

[0038] Step 1: Connection establishment phase

[0039] When node A and node B in the urban traffic network...

Abstract

The present invention provides a vehicle networking routing method based on node cognitive interaction, including the following steps, step 1, initialization of urban traffic road network; step 2, establishing node connection; step 3, screening relay nodes; step 4, completing Message delivery: high delivery rate, low network overhead, low end-to-end delay, effectively improving the efficiency of data transmission in the Internet of Vehicles environment, and adapting to the multiple factors of data transmission in the urban traffic road network environment.

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-...
