The nodes in the distributed network design of ship communication network, and realize the external wireless communication and remote satellite communication, the mobile network vulnerability detection node accurate positioning, to achieve timely diagnosis on the network fault. A mobile node localization method based on network transmission channel quantization tracking fusion is proposed. Node distribution model is firstly constructed ship communication network,data transmission between nodes for signal analysis in the multi-path channel ship communication network, and then the abnormal characteristics of channel quantization and fusion method for mobile node tracking fragile extraction, realize vulnerable node localization. At the end of experiment, the simulation results show that the accuracy of this method is higher probability of weak nodes position detection of moving ships in a communication network, costs less time, has utility in the communication network fault diagnosis.
