宽带卫星网络中基于Stackelberg模型的下载带宽分配策略*

宽带卫星网络中,下载带宽是非常宝贵的资源。而使用宽带卫星网络下载带宽的用户有着自身的特点,即下载带宽需求量不同。为此,本文将研究高效的的下载带宽分配策略。Stackelberg模型可以解决层次化资源合理分配问题。应用该模型,带卫星网络用户被分成两个组。一组是下载需求量大的用户组；另一组是,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分配策略的有效性。

Downlink bandwidth allocation strategy in broadband satellite network based on Stackelberg model

In broadband satellite network, downlink bandwidth is very valuable. The users of this network have their own characteristics, such as the different demand of downlink bandwidth. So this paper analyzes the efficient downlink bandwidth allocation strategy. The Stackelberg model is usually used to deal with the fair resources allocation problem. Appling this model, the broadband satellite network users are classified into two groups. The first group is the one who needs large amount of downlink bandwidth and the second is opposite. Then, the optimal function is built for each user. Using the solving method of Stackelberg model, the optimal downlink bandwidth is obtained for each user. The numerical simulation shows the effectiveness of the proposed allocation strategy.
