Proof-of-Concept of a SDN Based mmWave V2X Network for Safe Automated Driving

Conventional wisdom to enhance driving safety of automated vehicles focuses on the massive deployments of intelligent sensors, which generate enormous amount of data. As the solution of 5G era, creating a highly connected vehicular network is considered more reliable to guarantee the driving safety because single vehicle is prone to estimation error with blocked vision. Millimeter- wave, which is one of the key enablers of 5G, is promising to provide multi-gigabit ultra-high data rate and millisecond-level ultra-low latency data transmission. At the same time, software defined networking (SDN), which has proved its ability of dynamic resource management in wired networks, attracts us to extend its advantages into the vehicular environment. In this paper, we enumerate the benefits of mmWave and SDN on the vehicular network. In order to highlight their benefit on driving safety, we propose an architecture of SDN- based mmWave V2X network for HD dynamic map reception and distribution, i.e., cooperative perception. In addition, a proof-of-concept (PoC) is practically conducted in an outdoor environment to validate the performances of the proposed system.
