An adaptive transmission method based on cooperative communication in the environment of Internet of Vehicles

Abstract

The invention provides an adaptive transmission mechanism based on collaborative communication in the Internet of Vehicles environment, which characterizes all the information in the current Internet of Vehicles by data characteristic parameters, obtains the information value of each information, and determines the information that meets the conditions after processing according to its The value weights are arranged to determine the order of information transmission; starting from the target node, extract the node information traversed by the information and the corresponding neighbor node information parameters to obtain all valid information transmission paths from the sending node to the target node; calculate the path weight of each group to get All coordinated multi-path transmission networks between the departure node and the target node; the information sorted according to the value weight is sent to the target node through the determined multi-path transmission network to complete the information transmission. Based on the information value, the invention performs unified information characteristic parameter representation for a large amount of information, quantifies the weight of the information, performs selective transmission based on the information value, and realizes multi-path transmission in which nodes in the network cooperate with each other.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to an autonomous communication system based on collaborative communication in the Internet of Vehicles environment, which can reduce redundant information occupied resources and improve the reliability and efficiency of information transmission through effective screening of real-time information and optimization of transmission paths. Adapt to the transmission method. Background technique [0002] The application in actual traffic shows that the Internet of Vehicles is a special mobile ad hoc network with high-speed mobility, and the network will be frequently divided into many parts. Many different types of data information are widely distributed in the Internet of Vehicles, such as: text information, image information, audio information, video information, etc. A vehicle node is likely to become an isolated node due to environmental factors that cannot communicate with neighbo...

AI Technical Summary

Problems solved by technology

A vehicle node is likely to become an isolated child node due to the influence of environmental factors and cannot communicate with neighbor nodes. The connectivity of the network is frequently destroyed. Traditional routing protocols are difficult to adapt to the rapid topology changes of the Internet of Vehicles. After adopting the data low transmission efficiency
