Abstract: Power control is a key technique for resource management in wireless data networks. In order to get Pareto improvement for non-cooperative power control in wireless data networks, Stackelberg game is introduced to the power control game in wireless data networks, which makes all terminals in system work in the best equal SIR (Signal-to-interference),a new distributed power control algorithm based on Stackelberg game (SPG) is presented and been simulated. Numerical results suggest this algorithm can improve the capability of the system,terminals enjoy higher utility and lower transmit power relatively, the use of wireless resources become more rational and impartial, and the algorithm has good convergence.

Key words: wireless data networks, power control, Stackelberg game, utility, Nash equilibrium
