Ensuring Reliable V2X Communications by Simulation

​RT Spotlight San Francisco - V2X promises to improve safety on the road by relaying information among vehicles to help reduce collisions and loss of life. The technology must operate with extreme reliability in a very dynamic environment, with high relative speeds, very low latency for dynamic connections and safety-critical message receipt, in crowded urban environments with interfering signals. V2X systems will use competing technologies including DSRC and C-V2X. However, there are many issues which will need to be resolved. Congestion on the roads will affect the ability to communicate, and mitigation strategies need to be developed. Security of the networks will be needed for trustworthiness. Significant testing will be needed to guarantee interoperability among devices.

The presentation will explain how lab-based simulation that includes urban environments, vehicle mobility, fading, path loss, interference, and cyber security is being used with real radios in-the-loop, under varying conditions with thousands of moving vehicles, to greatly reduce testing time, space, and cost.
