The present invention provides a method for implementing multi-hop Internet of Vehicles. The Internet of Vehicles includes access routers, access nodes and vehicle nodes; each vehicle node is configured with X wireless interfaces, and each interface uses a different channel for communication. Each interface is uniquely identified by an interface ID i, and i takes a value from 1 to X. Each channel is uniquely identified by a channel ID. The channel ID of the channel used by the interface with the interface ID i is i, and X is a positive integer greater than 1; The node can obtain data from the nearest data provider through the multi-hop Internet of Vehicles data transmission implementation method provided by the present invention, thereby effectively reducing the delay and cost of obtaining data and improving the service quality. The present invention can be applied to road condition monitoring , Vehicle management and other fields, has a wide range of application prospects.
Description
technical field [0001] The invention relates to a realization method, in particular to a realization method of multi-hop Internet of Vehicles. Background technique [0002] In recent years, a lot of research work has been devoted to multi-hop Internet of Vehicles, so that drivers can quickly obtain data to ensure driving safety. With the development of vehicle network technology, multi-hop vehicle network will become a mode of providing services in the future. [0003] At present, the implementation mode of multi-hop car networking is realized through broadcasting, so the delay and cost are relatively large, which reduces the performance of data communication. Therefore, how to reduce the data communication delay and cost of multi-hop Internet of Vehicles has become a hot research issue in recent years. Contents of the invention [0004] Purpose of the invention: The technical problem to be solved by the present invention is to provide a method for realizing multi-hop In...
