Research On The Internet Of Things Storage And Event Triggering Mechanism Based On Semantic Ontology

Since the conception of the Internet of things(IoT)has been put forward,its meaning is changing.At present,it is generally believed that the basic function of the Internet of things is to achieve everything connected.According to the basic definition of IoT,there is a variety of networking devices in IoT,and the perceived environment of IoT is complex.From the data perspective,the size of data is huge,and types are in varieties and constantly changing.Therefore,Io T has own characteristics of the data storage and data management.From the perspective of response to the changeable environment,as an Intelligent networking,IoT should have a more flexible event trigger mechanism.From the point of making form and context in consistent,this paper looks at the data storage and event triggering of the Internet of things from the perspective of semantic ontology.In the aspect of data storage,we separate the abstract conceptual model of data analysis and the data instance of bearing specific information.This paper proposes a data storage model based on Ontology Conceptual Model and NoSQL technology,and use a substation of data storage model to describe the model.In the aspect of event trigger,we firstly combine the Ontology with Cybernetics to analysis conception of IoT with the result of giving a new definition of the "event" connotation;then,on this basis,an event triggered mechanism put forward in the perspective of software to meet the requirement of flexible triggered mechanism.According to the model of event trigger mechanism proposed in this paper,using ontology modeling software to build a knowledge base of ontology,and using VS2010 to develop a network simulation system.The simulation system simulates the networking equipment in the working of states maintenance,task execution,event triggered.The simulation results show that the event triggered mechanism of Internet of things based on semantic ontology and Cybernetics can well meet the needs of Internet event triggering.
