Research on reliable communication network for data concurrent transmission based on intelligent network connection system

Abstract

With the development of intelligent networking system for electric vehicles, the communication between intelligent electric vehicles has attracted more and more attention, and how to use multi-channel communication to realize data distribution is one of the research focuses. Firstly, the communication channel is modeled by Markov chain, and a discrete-time channel model is established, which is used for estimating and predicting the channel state. At the same time, using the idea of multi-channel and time synchronization, a concurrent transmission mechanism based on time synchronization is proposed to realize the synchronous transmission of data from multiple intelligent networks on multiple channels. Finally, the simulation results show that the average delay in the network can be reduced by about 30%. Therefore, the feasibility of the method is verified, and the method can effectively improve the performance of the communication network. This paper also gives a feasible solution to the overall architecture of vehicle communication network from the perspective of integration of WAVE and WiMAX technologies, and uses cross-layer integration design criteria and optimization methods to improve the performance of the new vehicle communication network.
