With the rapid development of automobile manufacturing and mobile communication technologies, the Internet-connected connected vehicles show new features such as a huge quantity of data, intelligence of communication, and diversification of user's needs, with a result that the information sensing, resource sharing and content distribution become new issue in the reality and reliability. To address these problems, this application studies the intelligent cooperative decision-making theory of network communications for Internet-connected connected vehicles based on vehicles’ network architecture and communication demands. Firstly, the extensible network architecture and communication model is designed to provide the theoretical foundation. Secondly, with the game theory, operational research and optimization mathematical tools, this application studies the collaborative information sensing based on the cooperation game, the collaborative task allocation strategy based on the dynamic programming, and the collaborative content caching strategy based on the edge computing, respectively. The specific objectives and results are to study the new features and requirements in the current networks and the rational allocation of the network resources. The proposal improves the accuracy of information perception, the efficiency of task allocation and content caching, the performance of the network systems and the user quality of experience. Moreover, the new theory presented in the application establishes the theoretical foundation for the intelligent collaborative decision making theory of network communications for Internet-connected connected vehicles.
