摘　　要：使用宽带卫星网络下载带宽的用户对于下载带宽需求量不同,为此,将研究高效的下载带宽分配策略。在博弈论中,Stackelberg模型可以解决层次化资源合理分配问题,应用该模型解决宽带卫星网络资源分配问题。宽带卫星网络用户被分成下载需求量大的用户组和下载需求量小的用户组,分别对其建立优化函数,利用Stackelberg求解算法得到各用户最佳的下载带宽。数值仿真实验验证了该分配策略的有效性。The users of broadband satellite network have their own characteristics,such as the different demand of downlink bandwidth. So this paper analyzed the efficient downlink bandwidth allocation strategy. The Stackelberg model was usually used to deal with the fair resources allocation problem. This paper applied this model to classify the broadband satellite network users into two groups. The first group was the one who needed large amount of downlink bandwidth and the second was opposite.Then,it built the optimal function for each user. Using the solving method of Stackelberg model,it obtained the optimal downlink bandwidth for each user. The numerical simulation shows the effectiveness of the proposed allocation strategy.
