摘    要:针对无线Mesh网在资源分配公平性方面存在的不足,提出了一种基于损耗因子动态优化权重的博弈算法,算法将博弈论融合在无线Mesh网的信道分配问题中,把节点间的竞争看作博弈参与者,采取博弈策略来竞争信道资源.针对信道分配过程中存在的损耗,引入损耗因子来动态更新博弈权重,使博弈能够按需索取,达到信道公平分配的目的.实验结果表明,改进算法使得网络吞吐量有所提升,并且保证了信道分配的相对公平.

关 键 词:无线Mesh网络  博弈  公平性  信道分配

Abstract:As there exists unfairness of channel allocation in wireless mesh networks, the paper proposes a game algorithm based on loss factor which can dynamically optimize weight.In this paper, the game theory is integrated into the channel allocation in wireless mesh networks, the competitive nodes are viewed as participants of the game, it adopts game strategy to compete channel resources.As there exists loss in the process of channel allocation, the loss factor is introduced to dynamically update the weight of game, make game demand demands, and ensuring the fairness of channel allocation.The experimental results show that the improved algorithm improves network throughput, and ensures that the channel allocation is relatively fair.
Keywords:Wireless Mesh Networks(WMN)  game  fairness  channel assignment
