Data mining, this is the whole fish bone drive a new term, is an abstract concept and improve the multidimensional-data bones application process data mining technology is applied to process optimization and structure of the data mining. End-to-end DMDF figure including complex data flow and different processing composition and improve the level of breeding. DMDF provide comprehensive platform and mixed methods to support the whole life cycle of comprehensive method data mining. Data pretreatment, data classification, association rules mining and prediction of the foundation and contact the whole life cycle of the data mining process. DMDF support several different mining components from the strategic level, tactics level of abstraction level, and then design a data mining system to realize the reasonable process execution buildings. Is a new direction DMDF structure of the data mining process.

This paper proposes an improved scale-free network model this paper introduces the traditional scale-free network theory and analysis methods of more appropriate wireless sensor network, it will be more close to the real wireless sensor network statement. The improved model is based on the complex network theory prove research more suitable to the wireless sensor network.
