The Wireless Sensor Network's Node Fault Diagnosis Method Based on Rough Set Decomposition Theory
Xi Xugang · Journal of Hangzhou Dianzi University · 2010
In the soil environmental monitoring system,the node fault diagnosis technology plays an important role to know the state of the network nodes.Because of the existence of node fault,the completeness of sensor network's monitoring data is affected.The paper proposed a decomposition approach for incomplete information system based on rough set evaluation functions,and a concrete example applied to the node fault diagnosis is given,to validate the effectiveness of this algorithm in processing incomplete information systems.
