摘要
提出了一种评价通信网节点重要性的多指标评价方法。分析论证了现有评价方法中各单指标的优缺点,提出将"不连通节点对数"、"剩余节点对最短距离和增量"和"生成树数减少值"三个单指标进行归一化的综合方法。该方法能对令现有多种方法失效的网络进行节点重要性评价,克服了现有各种方法的缺陷。试验分析表明:该方法简单有效、鲁棒性强。
A method of evaluating node importance in communication network with respect to multiple network performance measures was proposed.Every single measure in current method was analyzed. The number of unconnected pairs of nodes,the increase of the sum of the distance between every two nodes after certain node was deleted,and the reduction of the numbers of spanning trees were put forward or selected in the above mentioned integrated method.Current methods would be disabled in certain conditions due to their bugs,but this method adapts to many conditions.The experiments verify its efficiency and robustness.
