Research On Modeling For Sharing-oriented Sensor Resource

Along with the rapid development of information and network technology, humanbeings are striding fast towards the era of the Internet of Things. As the supporting ofInternet of Things, sensor technology plays an irreplaceable important role. Over theyears that people tend to be more concerned about the extension of the sensor functionand type, while rarely research on the issue of sensor resource sharing. But while thegrowing sensor network brings convenience to people, put the distributed andheterogeneous sensor resource sharing to a severe test. The information grid technologyis also developing rapidly along with the prosperity of the Internet of Things, which hasa unique advantage to resolve the issue of large-scale distributed resource sharing, andis propitious to the study of sensor resource sharing. Accordingly, it’s very meaningfulto start research on sensor resource sharing with the basic concept of the informationgrid technology.The integrative description of resource is the basis and priority in the series ofresearch on resource sharing, and the sharing model is the basis to on constructing aresource-sharing platform. Based on above considerations, this paper discusses threekey issues of sensor resource sharing under the information grid environment. The maincontents and achievements of this dissertation are listed as follows:(1) The SRASPIG problem is abstracted from the study, meanwhile，the maincontents of the study are put on three key technologies, resource integrative description,sharing network model and sharing optimization method. Finally, A SRASPIG problemsolving framework is given to deal with the three aspects.(2) Aiming at the resource integrative description technology, a method namedSGRIDM (Sensor Grid Resource Integrative Description Method) is proposed in thethesis firstly. Based on the definition of resource that is invented by RDF (ResourceDescription Framework), a more detailed formalized classification of sensor resourceunder the information grid environment is introduced. Moreover, A metadata model ofsensor grid resource is also designed which establish the foundation of the resourceintegrative description.(3) Directing to the sharing network model and the sharing optimization method,an active resource sharing model is proposed by combining the active service theorythrough the resource sharing process. Besides, an active sharing method based on keywords abstracting is given. The sharing mechanism is then described in detail, which includes the function and composition of the model.(4) Finally, this paper designs an actual example of sensor application under theculvert environment. By setting up a simulated computer environment and establishingthe data model in the environment of Visual Studio, the methods above-mentioned isproved reasonable and feasible.Given by the above-mentioned study, we get an effective method in the research onsensor resource sharing based on information grid, and fill in a gap of the research onsensor resource sharing.
