Research on the Hierachical Representation Model of IOT Based on RDF

Article Preview

Abstract:

With the development of Internet of Things(IOT), the method for intergrating information is with mufti-nodes and mufti-sources instead of single-node and single-source; heterogeneous information sharing and integration must also be solved. Focusing on this problem, the article discusses the key information integration technology in the heterogeneous environment of IOT, summarizes the information organization and expression of IOT, separates information sources from the network node, and defines node, information source and information item of IOT. Then the information model of heterogeneous system based on RDF is presented and the reference model of the five level interface protocols is designed. This design better meets the demands of distribution and heterogeneity of IOT nodes.
