Large-scale network accessibility model based on Internet of Vehicles communication base

Abstract

The invention provides a large-scale network accessibility model based on an Internet of Vehicles communication base. Considering the redundant characteristics of an Internet of Vehicles network node,an Internet of Vehicles network topology is given, namely the Internet of Vehicles communication base, and a heuristic algorithm is used to give a construction method of the communication base. Starting from the internal structure attribute and the dynamic characteristic of the communication base, and in combination with a smooth Gaussian-semi-Markov mobility model, the connectivity and stabilityof an Internet of Vehicles large-scale network are proved, and an Internet of Vehicles accessibility theoretical model is given; the theoretical model can accurately evaluate the network connectivityand stability under an Internet of Vehicles high dynamic environment, and provide a theoretical support for a network layer and provide real-time data guarantee for an application layer, so that stable and everlasting transmission of important information, such as traffic accident information and real-time media data and the like, in the Internet of Vehicles high dynamic network environment can be kept, which has important theoretical and practical application values.

Description

technical field [0001] The invention relates to the complex network field of the Internet of Vehicles. Background technique [0002] In recent years, domestic and foreign scholars' research on the network performance of the Internet of Vehicles has mainly focused on a specific scenario or the research on network connectivity based on certain assumptions. The existing research on the connectivity of the Internet of Vehicles mainly focuses on two aspects: (1 ) end-to-end connectivity; (2) overall network connectivity. [0003] The current research on end-to-segment connectivity mainly studies the connectivity probability between two nodes in a dynamic network environment. This kind of research is generally aimed at a certain road section in a highway or an urban scene, and models it as a 1-D network space, and then analyzes the relationship between nodes according to a certain node distribution model such as random distribution, average distribution, or Poisson distribution. ...

AI Technical Summary

Problems solved by technology

The end-to-end connectivity research mainly considers the use of node distribution model to analyze the relationship between the connectivity probability between two nodes in a small-scale network environment, vehicle density and communication radius, and does not study the network connectivity performance from the perspective of the overall network

However, the research on the overall connectivity of the network is generally based
