Abstract:

Cellular vehicle-to-everything (C-V2X) is an important direction of the development of intelligent and connected vehicles.In order to improve the quality of data transmission in the communication process, the average end-to-end communication delay, delay jitter degree and packet loss rate were calculated, and a transmission loss function was proposed to represent the performance of the system.A dedicated short range communication (DSRC) short message (DSM) data transmission strategy based on transmission loss function was designed and implemented, and it was compared with transparent transmission strategy.The test results show that compared with the transparent transmission strategy, the transmission loss of the proposed data transmission strategy decreases by 48.95%, 52.96%, 47.79% and 50.86% under the four scenarios of static straight track, static curve, dynamic straight track and dynamic curve.The proposed message transmission strategy ensures the comprehensive optimization of the effectiveness, stability and reliability of the direct network communication.

Key words: Internet of vehicles, transmission loss function, data transmission strategy, DSM
