摘要: 为选择有代表性的、较全面反映链路质量的参数,提出了基于动态直觉模糊多属性决策的链路质量参数优选方法.从链路质量评估的稳定性和敏捷性出发,以4种不同链路质量等级下的决策矩阵作为优选依据,采用优劣解距离法得到备选参数集的排序,并进行筛选,根据贴近度对筛选后的备选参数集进行加权平均融合,得到优选的基于动态直觉模糊多属性的链路质量参数.实验结果表明,与平滑后的包接收率、模糊链路质量评估器(F-LQE)相比,采用优选的链路质量参数具有较强的稳定性和敏捷性.

Abstract: To select typical and comprehensive parameters reflecting link quality, an optimization approach was proposed based on dynamic intuitionistic fuzzy multiple attribute decision making. Considering stability and agility of link quality estimation, a method for order preference by similarity to an ideal solution was employed to get sorted parameters in candidate set according to decision making matrix coming from four different link levels, so that parameters are selected from sorted parameters. Based on the closeness of selected parameters, the selected parameters are fused with weighted average so as to achieve optimized link quality parameter which is the quality indicator based on dynamic intuitionistic fuzzy multiple attribute decision making (DMD-LQI). Experiments show that comparing with smoothed packet reception ratio (SPRR), fuzzy link quality estimator (F-LQE), the optimization approach is of better stability and agility.
