V2X communication system for sharing road alert information using cognitive network
Kenta Ito, Koji Hashimoto, Yoshitaka Shibata · 2017
We developed a system for deterring traffic problems by understanding the road surface condition, collecting information from many vehicles and calling attention at various levels to the driver. We focus on the sharing method of sensor data with road condition using V2X communication. The Wi-Fi communication in the 2.4 GHz band which is the conventional method, has a short communication distance and must understand the communication partner in advance. We use 920 MHz band communication which is long distance communication to compensate for these problems. We propose a cognitive network method to optimize V2X communication by combining both WiFi and 920MHz bands.
