Problems solved by technology
[0004] Current researchers have proposed a mode in which the Internet of Vehicles obtains network services by accessing the IPv6-based Internet and defined the corresponding protocol stack. However, due to the incompatibility between the architecture of the Internet of Vehicles and the IPv6 network, the existing access methods have some limitations.

Embodiment 1
[0159] Based on the simulation parameters in Table 1, this embodiment simulates the implementation method of the Internet of Vehicles in the present invention, and the performance analysis is as follows: when the vehicle density is constant, as the speed of the vehicle node increases, the delay for the vehicle node to obtain network service data And the cost decreases accordingly, the main reason is that with the increase of vehicle node speed, the distribution area of vehicle nodes with network service data is wider. In the present invention, vehicle nodes obtain network service data from the nearest vehicle node, so the service data The cost and latency decrease as the speed increases. The average delay for vehicle nodes to obtain data is 40ms, and the cost is 5

The invention provides a communication realization method of the next-generation city internet of vehicle. The internet of vehicle comprises four types of nodes including boundary access routers, access routers, access nodes and vehicle nodes. The boundary access routers are connected with the routing backbone network of the next-generation internet. The access routers are connected with the boundary routers. The access nodes are connected with the access routers. The internet of vehicle comprises more than one roads and more than one road intersection points. Each road intersection point is identified by one virtual node. The road between the two adjacent virtual nodes is called a road segment. Each road segment is provided with one access node. Area covered by all the access nodes connected with one access router is called a sub-network. The internet of vehicle is divided into more than one sub-networks. The vehicle nodes drive along the roads and have routing and forwarding functions.
Description
technical field [0001] The invention relates to a method for realizing communication, in particular to a method for realizing communication of the next-generation urban Internet of Vehicles. Background technique [0002] As a new type of vehicle communication network, the Internet of Vehicles can realize multi-hop wireless communication between vehicles and between vehicles and roadside infrastructure. With the continuous development of the Internet of Vehicles technology and the continuous emergence of various new applications, it is urgently required that the Internet of Vehicles can be connected to the Internet to meet the rapidly growing application needs of users. [0003] As a special type of mobile ad hoc network, Internet of Vehicles has the characteristics of fast moving speed, large number of nodes, and large coverage area. The Internet based on IPv6 (hereinafter referred to as IPv6 network) has the advantages of mobility support, abundant address resources, and s...
