IOV large-scale network interconnected and intercommunicated communication base component construction method

Abstract

An IOV large-scale network objectively has low interconnection and intercommunication coupling degree due to the characteristics of enormous IOV large-scale network nodes in city scenes, frequent topological change, crisscrossed roads and the like. For the above problem, by considering the IOV network node redundancy characteristics, an IOV network topological structure, namely an IOV communication base, is provided; and furthermore, a communication base construction method is provided by utilization of a heuristic algorithm. By means of the IOV large-scale network interconnected and intercommunicated communication base component construction method in the invention, the problems of signal interference, network congestion and low communication efficiency due to the fact that IOV large-scale network redundant nodes substantially participate in communication in a city scene can be effectively solved; the IOV large-scale network interconnected and intercommunicated real-time performance and stability can be improved easily; and simultaneously, relatively high transmission efficiency can be provided for design and operation of IOV application services.

Description

technical field [0001] The invention relates to the complex network field of the Internet of Vehicles. Background technique [0002] In the Internet of Vehicles, the IEEE802.11p standard is used for communication between nodes, and most distant vehicles or between vehicles and roadside infrastructure cannot communicate directly, and must rely on intermediate nodes to forward and receive messages. In the large-scale Internet of Vehicles in the urban scene, there are a large number of nodes, and the nodes have redundancy characteristics. In this way, a large number of intermediate nodes will participate in forwarding data during network communication, resulting in increased signal interference between nodes, which is likely to cause network congestion. Due to problems such as sending delays, it is difficult to guarantee network interconnection. In the case of node redundancy, if the information transmission process uses a simple flooding (Flooding) method, that is, each vehic...
