Abstract: Given that links are under throughput requirements, the impact of selfish rate adaptation behavior on the network performance is studied. The existence of the optimal transmission strategy is proved, and a repeated dynamic game is proposed. It is found that the link scheduling order affects the feasibility of the throughput requirement and the total power consumption. A pricing function is introduced to motivate links to share channel fairly and efficiently. Simulation results show that the proposed approach leads to not only more feasible solutions, but also less power consumption.

摘要： 研究在满足吞吐量要求的前提下链路自私的速率调整行为对网络性能的影响。证明最优传输策略的存在性，提出一个重复的动态博弈，发现链路调度顺序会影响吞吐量要求的可行性及总功率消耗。引入定价函数，促使链路公平有效地分享信道。模拟实验结果表明，采用定价函数不仅导致更多的可行解，而且降低了能耗。
