摘要: 功率控制是无线数据网络中资源管理的关键技术。为使无线数据网络中非合作博弈功率控制算法得到帕累托改进,将斯塔克尔博格博弈引入到无线数据网络功率控制算法中,使所有系统终端都工作在最佳的等信干比下,提出一个基于斯塔克尔博格博弈的分布式功率控制算法,并进行了数值仿真。仿真结果表明,该算法明显提高了系统的性能,使系统终端具有相对较高的效用和较低的发射功率,并使得无线网络资源的使用更加合理和公平,同时算法拥有较好的收敛性。

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.
