The invention provides an adaptive transmission mechanism based on cooperative communication in an Internet of Vehicles environment, and the mechanism comprises steps of carrying out the data featureparameter representation of all information in the current Internet of Vehicles, obtaining the information value of each piece of information, and arranging the processed information meeting the conditions according to the value weights of the information, so as to determine an information transmission sequence; starting from the target node, extracting node information of information traversal and corresponding neighbor node information parameters to obtain all effective information transmission paths from the sending node to the target node; calculating the path weight of each group to obtain all coordinated multi-path transmission networks between the starting node and the target node; and sending the information sorted according to the value weights to a target node through the determined multi-path transmission network to finish information transmission. According to the method, based on the information value, unified information characteristic parameter representation is carriedout on a large amount of information, the weight of the information is quantified, selective transmission is carried out according to the information value, and cooperative multi-path transmission ofnodes in the network is achieved.
