Summary:
Radio environment estimation is an important technology to realize reliable vehicle-to-vehicle (V2V) communications. However, in V2V communications, it is difficult to estimate radio environment characteristics accurately owing to the dynamic change of surrounding environments. Mainly, a received signal power significantly fluctuates by obstacle vehicles between a transmitter and a receiver. In this paper, we propose a simple power control method for V2V communications existing an obstacle vehicle. The proposed method first estimates the empirical cumulative distribution function (CDF) of the instantaneous received signal power based on the actual measurements. Then, the power control is performed using the estimated CDF. The simulation results clarify that the proposed method can enhance the efficiency of the transmission power while precisely guaranteeing a permissible communication quality.
