A Semantic-Based Architecture for Sensor Data Fusion

In this paper, we present a three-layer flexible architecture which intends to help developers and end users to take advantage of the full potential that modern sensor networks can offer. The proposed architecture deals with issues regarding data aggregation, data enrichment and finally, data management and querying using semantic Web techniques. Semantics are used in order to extract meaningful information from the sensorpsilas raw data and thus facilitate smart applications development over large-scale sensor networks. We describe an open, standards-based, modular architecture which is based on the current standardization efforts of the open geospatial consortium (OGC) and extends them to support semantic Web techniques comprising a core of reusable components and interfaces for supporting different types of services, through Web technologies.
