Based on FPGA Switching Mechanism Design for Low Latency Transmission of 802.11p-LTE Hybrid Networks

The reliable and real-time transmission of V2X is one of the current research hotspots of the Internet of Vehicles. Currently, the mainstream applications include the LTE-V protocol and the IEEE802.11p protocol of the LTE system, but both have certain limitations and cannot meet all the requirements of vehicle networking communication. A hybrid heterogeneous network that combines the advantages of the two is an efficient and convenient solution, and is also a trend of future development. This paper mainly studies the transmission and handover mechanisms of 802.11p and LTE-v collaborative networks, and designs a heterogeneous link fast switching module based on FPGA to provide protection for low latency information transmission in the Internet of Vehicles.
