基于纳什议价合作博弈论,针对IEEE 802.16无线Mesh网络中不同信道情况下的流量控制问题,提出了一种最大化网络整体效用的流量控制方法.该方法以IEEE802.16无线Mesh网络端到端的业务流为研究对象,基于纳什议价解(NBS)框架,结合自适应调制编码技术,设计了一种节点速率优化控制机制.实验结果表明,所提方法能兼顾用户的收益和公平性,并能最大化网络的整体效用.
This paper considers the flow control of IEEE 802.16 wireless Mesh networks in different channel conditions and proposes a flow control method with maximized aggregated utility based on the cooperative game theory of Nash bargaining solution(NBS).In this method,the NBS mechanism is combined with the adaptive modulation and coding technology for the end-to-end service flow in IEEE 802.16 wireless Mesh networks,and a control mecha-nism for the service flow rate of source nodes is presented.Simulated results show that the proposed method maintains a good balance between the profit of users and the fairness among service flows,and that it maximizes the aggregated utility of the whole network.
