Summary:
Vehicle-to-vehicle (V2V) communications have been continuously studied to realize reliable autonomous driving systems. Conventional works have clarified that multiple obstacle vehicles between a transmitter and a receiver have a strong effect on radio propagation characteristics. It is necessary to design communication parameters according to the number of obstacle vehicles for improving the robustness of V2V communications. This paper describes a method to estimate the number of obstacle vehicles using a small sample size based on a p-value, which is typically utilized in hypothesis testing. The cloud server first calculates the average received signal power for each number of obstacle vehicles assuming that each number is known. Subsequently, the number of obstacles is estimated by using newly reported samples. The simulation results reveal that the proposed method can accurately predict the number of obstacles using a small sample size.
