| 摘要: |
| 对于多业务流的网络选择问题,提出了一种在网络侧进行的基于二分图匹配网络选择机制,根据业务流对于每个接入网络的满意度,网络侧实体进行统一的分配,在保证公平性的前提下使得分配结果的满意度最大.对算法的代价和性能进行了分析.实验结果表明,算法能够达到较大的网络整体满意度,并且具有较大的公平性系数. |

| Abstract: |
| The existing methods are mostly concentrated on single flow network selection. In this paper, a multi-flow network selection model scheme based on bigraph is proposed. By calculating the satisfactions between flows and networks this scheme can distribute the flows with the most satisfaction on the condition of being fair. Analysis of the performance of the algorithm proves the correctness of Algorithm. Numerical results show that the proposed schemes achieve significant satisfaction and Fair coefficient. |
