Research of Heterogeneous Network Protocol Data Fusion in Smart Home Control System Based on Spatial Outlier

A large number of intelligent network control protocols are used in the field of the internet of things. But a variety of network protocols have different data formats, inconsistent transmission mode and various solutions, etc. Especially the processing of uncertain data. To integrate IP networks, ZigBee wireless sensor network and the GPRS mobile phone network data, a solution is proposed to deal with the fusion of a variety of heterogeneous network protocol data in the paper, which achieves seamless switching and forwarding data between heterogeneous networks under multi-protocol. For the uncertain data obtained by the sensors, an algorithm is also proposed, the correlation calculation and determination algorithm of uncertain data streams which determines the credibility of these data. The final decision-making conclusions will be done based on judgment decisions by solution rules. Based on the two above methods, the smart home control system is designd and realized in this study. The results show that system and algorithms are feasible and validate, it achieves seamless switching and forwarding of data between heterogeneous networks and effectively identifies the uncertain data.
