摘要

The Fifth Generation of Mobile Communication/ Beyong Fifth Generation of Mobile Communication (5G/B5G) is an indispensable communication technology in the wireless communication system. Its ultimate goal is to realize the information exchange between the vehicle and all the surrounding wireless communication devices. However, a large amount of interactive information is widely spread, user nodes have strong mobility and openness, and the network topology changes rapidly in the Internet of Vehicles (IoV), which makes the communication links change frequently and interrupt easily. In this paper, the relay cooperative transmission technology is applied to the IoV. Based on the design of relay selection algorithm and the analysis of system performance, the influence of relay selection algorithm on the reliability and stability of IoV communication is studied. Simulation results show that the proposed scheme can significantly improve the system throughput and relay switching times.
