I research vehicle communications networks, connecting cars to cars and to transportation infrastructure like traffic lights—for tomorrow’s vehicle-to-everthing (V2X) networks. These complications, at least at the simulation level, did not slow down the V2X network. To date, our published research on O-RAN V2X has centered around a computer simulation only. After all, no one will trust a V2X network to do anything if that network’s cyber vulnerabilities haven’t been anticipated and patched in advance. Realizing the O-RAN V2X vision will require progress on multiple fronts simultaneously.
