基于模糊层次—熵权法的自适应垂直切换算法

open access: yesGuangtongxin yanjiu, 2021
针对当前异构网络中,采用多决策属性的垂直切换算法难以动态调整网络属性的权重值,从而无法满足用户服务质量(QoS)的需求问题,文章以接入最优的异构无线网络和保障用户QoS为目标,提出基于模糊层次—熵权法的自适应垂直切换算法。首先,根据用户对网络属性的不同要求,采用主观模糊层次赋权与客观熵权法结合的方式构建网络属性优化模型,之后根据用户体验采用自适应机制来动态地调整各网络属性权重值,最后利用成本函数对异构网络的状态进行切换预测,从而选择接入最优的无线网络。仿真实验表明,所提算法能有效降低网络切换率 ...
