Estimation of Communication Range Using Wi-Fi for V2X Communication Environment

In this paper, we introduce an estimation of communication range using Wi-Fi for V2X communication environment. Traffic accidents and traffic hazard are serious social problems. Understanding road condition in advance is important and necessary to prevent traffic accidents and traffic hazards. In addition, getting information without Internet connection is necessary to provide road information for drivers in real-time because there is an environment that getting Internet connection is difficult. We construct a road condition sharing system with multiple vehicles using V2X communication. Our goal is to share road condition without Internet connection. To realize our goal, we experiment V2X communication, evaluate experimental results and estimate communication range.
