A New Pricing Function for Power Control Game in Wireless Data Networks

— This paper presents a new pricing function for noncooperative power control game in a single cell CDMA data network. Considering a utility function for each terminal, the purpose of power control in wireless data networks is to maximize network utility. In the proposed game, the pricing function is a linear function of the terminal’s Signal to Interference plus Noise Ratio (SINR). We first prove that the new game is a supermodular game and then we show the strategy space of the new game is such that it is possible to reach better equilibrium point compared to pricing function based on terminal’s power. Simulation results show that the game with the proposed pricing function can improve the utility and power consumption of the terminals at equilibrium.
