Abstract: 为抑制无线Mesh网络中的信道振荡和提升网络效用,综合分析路由端和用户端信道振荡产生的因素.引入演化博弈理论,联合改进的果蝇优化算法提出基于ESS-PFOA(Evolutionary Stable Status-Promoted Fruit-Flies Opti-mal Algorithm)算法的分布式信道分配策略.实验分析发现当信道振荡宽容因子β≤0.5时网络呈同构特征,β>0.5时网络向异构转化,β≥0.9时网络呈异构特征;网络效用和信道振荡抑制率与信道振荡宽容因子β紧密相关.仿真结果表明,ESS-PFOA算法的信道振荡率从0.44下降至0.08,在异构网络环境下其网络收益和信道振荡抑制率明显占优,能有效提高网络效用.
