一种基于两测度的无线链路重要性评价方法

A Method for Estimating the Importance of Based on both Sides of the Wireless Networks Link

基于现实中的网络往往为非对称网络,各条串接链路之间也不是对称的关系,故将某些串联链路的重要性视为相等是不妥当的。该文提出了一种评价无线网络中每条链路重要性的新方法———两测度法,并给出了归一化表达式。通过比较第i条链路失效时整个网络的生成树数目和节点两两之间最短距离的总和,来评价第i条链路的重要性。该方法可以用来判断全网络链路的重要性,并比较任意两条链路的相对重要性,实验结果证明了该方法的正确性。

Based on the reality of the network are asymmetric network,link between each of the series is not a symmetrical relationship,therefore the importance of certain serial link is not appropriate as equal.A both sides of law degree method for estimating the importance of node in wireless networks is proposed.A generalized expression for computing the node score is given.By comparing the i-th link fails the number of spanning tree nodes and the shortest distance between any two sum evaluate the importance of all network links,and compare the relative importance of any two links,the experimental results prove the correctness of the method.
