%X Faulty links are a typical network fault symptom in wireless sensor network.It affected the operation of network and the quality of service seriously,therefore faulty links need to be detected and repaired.Localization technique of faulty links based on simple network tomography was introduced.This paper presented a binary disjunctive model for describing link faulty states;the localization problem of faulty links is referred to as the Maximum A-posteriori Probability problem.By making the Localization prob...
