Research on Communication Delay Mechanism of Intelligent Network Connected Vehicle Data Transmission System

With the rapid development of information technology and the increasing maturity of intelligent vehicle network technology, the Internet of Vehicles system is an important part of intelligent transportation, and the real-time and accuracy of its data transmission is very important to improve road traffic efficiency and safety. This paper discusses the mechanism of communication delay in automobile intelligent network data transmission system in detail, analyzes the key factors affecting the transmission distance, transmission speed and network congestion of communication delay signal, and proposes an optimization method of cache strategy based on popularity and location prediction. The effectiveness of the strategy is verified by simulation experiments and practical tests, which provides strong support for the further development of automotive network systems.
