Enhancing 5G Broadcast Services in Large-Scale IoV Networks Using Reliable RIS Relaying

The advent of 5G technology and new energy radio communication systems heralds a significant shift in the landscape of automated driving. This paper focuses on the integration of 5G and broadcast services in the realm of new energy automatic assisted driving, emphasizing the importance of reliable, energy-efficient communication in the large-scale IoV. The enhanced capabilities of 5G enable improved vehicle battery endurance while safeguarding user data privacy and road traffic safety. We introduce RIS relay reflection as a novel approach to optimize non-line-of-sight links, presenting a RIS-assisted communication model tailored for 5G-enhanced large-scale IoV. The paper evaluates the trustworthiness of RIS relays using user behavior data, proposing a reliable and energy-efficient communication scheme that incorporates RIS security relay assistance. This scheme ensures the selection of trustworthy relays, synergizing the beam direction of transmitters and RISs for optimal 5G broadcast service delivery and OTA updates. Our approach promises to revolutionize communication in large-scale IoV systems, paving the way for a more connected and efficient future in automated vehicle networks.
