A novel ontology for sensor networks data

Abstract

Sensor networks have seen an exponential growth in the last few years. They involve deploying a large number of small sensing nodes for capturing environmental data. Searching such networks is limited by two major constraints: scalability and precision. We argue that the key to enabling scalable and precise sensor information search is to define an ontology that associates sensor information taxonomy for searching and interpreting raw data streams. We present the motivation and description of the development of the proposed ontology, partial evaluation of the early prototype ontology, a discussion of design and implementation issues, and directions for future research works.
