Embodiment 1

[0218] Based on the simulation parameters in Table 1, this embodiment simulates a method for real-time communication of road safety information based on the Internet of Vehicles in the present invention. The performance analysis is as follows: when the amount of data decreases, the network performance increases, and the packet loss rate decreases. When it increases, the network performance decreases and the packet loss rate increases. The average success rate of vehicle nodes to obtain service data is 99.37%.

Abstract

The invention provides a real-time communication method of road safety information based on vehicle networking. The vehicle networking comprises a base station, a vehicle node, an access node, a router and a server. Each access node and the base station have unique coordinates, and the access node and the base station use different protocols to communicate. The access node is arranged on both sides of the road covered by the vehicle-mounted network. The method provided by the invention can quickly obtain service data, shorten the delay and cost of obtaining service data, and improve the service quality. The invention can be applied to the fields of road condition monitoring, vehicle management and the like, and has a wide application prospect.

Description

technical field [0001] The invention relates to a communication method, in particular to a method for real-time communication of road safety information based on the Internet of Vehicles. Background technique [0002] The Internet of Vehicles is a service model that is built on vehicles and can provide local services. In recent years, a lot of research work has been devoted to the Internet of Vehicles in order to enable vehicle drivers to quickly obtain network services. With the development of network technology, the Internet of Vehicles will become a mode of providing services in the future. [0003] At present, the implementation mode of the Internet of Vehicles 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 providing services in the Internet of Vehicles has become a hot research issue in recent years. Contents of the invention [0004] Pur...
