摘要
简要介绍了博弈论的基本原理和非合作博弈功率控制模型,为了改进非合作博弈中终端的不公平性,将合作博弈引入到功率控制中来,使得系统中所有终端都工作在最佳的等信干比下,并推导出一个分布式基于合作博弈的功率控制算法。仿真表明,该算法明显提高了系统的性能,系统中终端具有相对较高的效用和较低的发射功率,还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。
The basic principle of game theory and the model of non-cooperative power control game （NPG） presented for wireless data network are introduced. In order to ameliorate unfairness between terminals in system, the idea of cooperative game is introduced to this model; a new distributed algorithm based on cooperative game （CPG） is presented. Numerical results suggest this algorithm can improve the capability of the system; terminals have higher utility and lower transmit power relatively, make terminals use the wireless resources more rational and impartial, and the convergence of the algorithm is good.
