摘　　要：根据Ad hoc网络的分布式特性,提出一种新的以干扰为代价的非合作功率控制博弈算法,让产生较大干扰的发送节点受到更多惩罚,验证其存在唯一的纳什均衡。仿真结果表明,该算法具有较快的收敛速度,与NPG和NPGP模型相比,可以有效抑制产生较大干扰的链路的发送功率。在保证链路接收信号质量的同时,不仅有效减小干扰以提高网络容量,而且还在一定程度上兼顾了节点之间的公平性。According to the distributed characteristic of Ad hoc network, a new non-cooperative power control game algorithm at the cost of interference is proposed. Thus the transmitting nodes which generate fairly interference would receive more punishment, verifying the unique nash equilibrium of the proposed algorithm. The simulation results indicate that this algorithm has quick convergence speed and could effectively restrain transmitting power of the link with high interference as compared with NPG and NPGP. While ensuring the received signal quality of the link, the interference is reduced, the network capacity effectively improved, and the equality among different nodes considered in a certain degree.
