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.
In order to choose a representative parameter that reflects the quality of the link in a comprehensive way, a link quality parameter optimization method based on the dynamic intuitionistic fuzzy multi-attribute decision-making is proposed.From the stability and agility of the link quality evaluation, The quality of the link under the decision matrix as a preferred basis, the use of superior and inferior solution distance method to obtain the order of the alternative parameter set, and screening, according to the degree of close selection of the candidate parameter set after the weighted average fusion, the preferred based on Dynamic intuitionistic fuzzy multiple attribute link quality parameters.Experimental results show that the proposed link quality parameters are more stable than the smoothed packet receiving rate and fuzzy link quality estimator (F-LQE) And agility.
