摘要

Abstract

The performance of the existing efficient topology inference algorithm is highly sensitive to the threshold . To address the problem , a finite mixture model based topology inference algorithm is proposed . Firstly , a leaf node is selected from the original leaf‐node set , and then the similarities between the node and the other leaf nodes are measured , after which the original leaf‐node set is roughly divided into several subsets using the finite mixture model based on the measured similarities . The internal nodes corresponding to each subset could be inferred afterwards . Subsequently , the above procedures are applied for each subset obtained from rough division , and the process is iterated until all of the internal nodes are found . Analysis and simulation show that the proposed algorithm needs less correlation data than the existing algorithm , and performs almost as well as the existing algorithm with the optimum threshold .
