- Abstract:
-
A probing path selection algorithm based on active probing is proposed to solve the problem of existing fault localization algorithms’ inability to meet the requirements of multi-node failure localization, especially when a large number of failed nodes are present in the network. The algorithm mainly includes the greedy path selection algorithm for fault detection, which is used to iteratively select the probing path with the minimum weight to cover the nodes in the network, and the tabu link search algorithm for fault localization, which is used to generate the candidate path set multiple times to select the most suitable probing paths and thus solve the problem of multi-node failure localization. Simulation results on random network topologies and real network topologies show that the probing path selection algorithm has a higher successful localization ratio and lower probing cost than the existing node failure localization algorithms.
