In this paper, we investigate a directional CSMA/CA protocol for mmWave vehicle-to-vehicle communications when location information is given with an observational error. Considering this inaccuracy, we propose a directional CSMA/CA where location-based selective RTS/CTS and beam alignment are applied. Numerical evaluations verify that the proposed algorithm improves packet reception ratio and data rate compared to a directional CSMA/CA that does not utilize the location information.
