RESUMO

In the recent years, the volume of data available from wireless sensor networks (WSN) has increased considerably. WSN is a technology that allows the development of applications in various types of environments (pervasives, Ubiquitous, controlled and with difficult access environment), doing that concern for content managing is greater. Among the proposals, many use ontologies as a way to organize and categorize data; there are two key issues in data management in WSN: data storage and query processing. The present work proposes a semantic approach to the management of dynamic and static data from the network, providing a metadata service on WSN and its applications; this technique is based on the construction of ontologies that allows scalability, enhancement of efficiency in the activities of the environment and reusability. It was verified by means of tests based on querys on the ontology that the proposed model is appropriate, and that the search based on semantics provided retrieval of data from WSN more adequately, as compared with traditional approaches.
