摘要： 在满足网络吞吐量要求的前提下，研究节点的自私功率控制行为对网络性能的影响。针对非相干频移键控调制方式，证明最优传输策略的存在性，提出一个重复的动态博弈。由于链路会将发送功率从干扰较高的时间段移到干扰较低的时间段，该博弈在某些情况下无法收敛，因此引入惩罚函数确保该博弈收敛，并通过模拟实验验证该方法的有效性和正确性。

Abstract: Under throughput requirements, the impact of selfish power control behaviors on the network performance is studied. Employing the modulation scheme Non-coherent Frequency Shift Keying(NFSK), the existence of the optimal transmission strategy is proved, and a repeated dynamic game is proposed. Since links are motivated to move the transmission power from high interference durations to low interference ones, this game can not converge in some cases. A penalty function is introduced to ensure convergence, which is verified by simulation.
