摘要
传统基于AHP的激光通信最优节点选取方法在最优节点选取过程中,仅采用AHP赋权方法,获取的指标权重主观性较强,导致最优节点选取结果存在偏差,提出基于TOPSIS算法的激光通信最优节点选取方法。构造激光通信节点优秀程度指标的规范化选取决策矩阵;通过结构熵权法获取主客观相结合的激光通信节点权重,采用变异系数方法消除指标间量纲不同的影响,获取激光通信节点综合权重;基于综合权重与规范化选取决策矩阵构造激光通信节点加权规范化选取决策矩阵;在此基础上计算不同激光通信节点与权重指标的相对贴近度,获取不同激光通信节点优秀程度排序,实现激光通信最优节点的选取。实验结果表明:所提方法能够准确选取激光通信最优节点,具有低能耗、低传输延时的优势。
In the traditional AHP based optimal node selection method of laser communication,only the AHP empowerment method is used in the optimal node selection process. The index weight gained by the optimal node is more subjective,resulting in the deviation of the optimal node selection results,and the optimal node selection method based on the TOPSIS algorithm is proposed. The decision matrix is selected for the standardization of the excellent degree index of the laser communication node,and the weight of the laser communication nodes combined with the subjective and objective view is obtained by the structure entropy weight method. The variation coefficient method is used to eliminate the different influence of the index interval,and the comprehensive weight of the laser communication node is obtained. Based on the comprehensive weight and standardization,the decision moments are selected. The decision matrix is selected by weighted normalization of the laser communication node of array structure;on this basis,the relative degree of relative closeness between different laser communication nodes and weight indexes is calculated,and the excellent degree sorting of different laser communication nodes is obtained,and the selection of the optimal node of the laser communication is realized. The experimental results show that the proposed method can accurately select the optimal node for laser communication,and has the advantages of low energy consumption and low transmission delay.
