Semantic-addressable messaging network based on event ontology for sensor and controller network

With the rapid development of sensor networks, the problems, such as how to improve the efficiency of data transmission, how to make sensor network more intelligent, are focused by more and more researchers. In this study, we propose an integrated solution, in which a semantic-addressable messaging network is created and overlaid on an IP network, and then, an event ontology method is used to analyze the data of sensor network and the analysis results are then used for the controller of sensor network. Based on this proposal, 1) the nodes of messaging network can be divided into some related groups according to the message tags and semantic dictionary, therefore, this approach can be used to reduce the transmission hop destinations by creating a series of virtual layers on messaging network; 2) the event ontology method can be used to control the sensor network according to the event conditions. Furthermore, this approach can be used to improve the performance for wide fields such as smart-grid, big data exchange in real time.
