Embodiment 1

[0158] Based on the simulation parameters in Table 1, this embodiment simulates the vehicle-mounted cloud implementation method in the present invention, and the performance analysis is as follows: when the vehicle node speed is constant, as the vehicle node density increases, the number of cloud members also increases, and the distribution The area is wider, so the delay and cost of obtaining service data are reduced. The average delay for vehicle nodes to obtain service data is 40ms, and the average cost is 10.

Abstract

The vehicle-mounted cloud includes a vehicle-mounted network connected to the IPv6 Internet. The vehicle-mounted network includes K access routers and more than two vehicle nodes. Each access router ARk is uniquely identified by its own geographical coordinates (xk, yk), 1≤ k≤K, the geographical coordinates of each access router are unique in the vehicle network; the vehicle node has a routing and forwarding function, and the vehicle node realizes communication with the IPv6 Internet through the nearest access router; an access router and All the vehicle nodes communicating through it are constructed into a subnet, and the present invention obtains service data in a unicast manner, thereby reducing delay and cost of obtaining service data and improving service quality.

Description

technical field [0001] The invention relates to a data communication method, in particular to a data communication method based on a vehicle cloud. Background technique [0002] The vehicle cloud is a service model that is built on the vehicle network and can provide local services. In recent years, much research work has been devoted to in-vehicle cloud in order to enable vehicle drivers to quickly obtain network services. With the development of in-vehicle network technology, in-vehicle cloud will become a mode of providing services in the future. [0003] At present, the implementation mode of in-vehicle cloud is realized through broadcasting, so the delay and cost are relatively large, which reduces the performance of network services. Therefore, how to reduce the delay and cost of in-vehicle cloud services has become a hot research topic in recent years. [0004] The present invention realizes the vehicle-mounted cloud by means of unicast instead of broadcasting, the...
