A Game Theoretic Approach to Power Control in Vehicular Communication Systems

Abstract: Vehicular-to-network (V2N) communication is a key enabler in various intelligent transportation system services currently investigated by global standards bodies and European projects. In this master thesis, we study the impact of pilot and data power setting on the uplink performance of V2N communications. Specifically, we consider the “urban” and “rural” scenarios specified by the 5G Infrastructure Public Private Partnership project called 5GCAR, and use the the recommended base station and vehicular user equipment parameters in the 5 . 9 GHz band. We study a distributed non-cooperative game theoretic algorithm to determine the pilot-data power ratio for each vehicle. Numerical results indicate that the proposed distributed algorithm converges to the Nash equilibrium, and that the mean squared error (MSE) of the received data symbols decreases compared with the MSE obtained by a centralized benchmark algorithm.
