Data Management in Sensor Networks Using Semantic Web Technologies

چکیده
The increasing availability of small-size sensor devices during the last few years and the large amount of data that they generate has led to the necessity for more efficient methods regarding data management. In this chapter, we review the techniques that are being used for data gathering and information management in sensor networks and the advantages that are provided through the proliferation of Semantic Web technologies. We present the current trends in the field of data management in sensor networks and propose a three-layer flexible architecture which intends to help developers as well as end users to take advantage of the full potential that modern sensor networks can offer. This architecture deals with issues regarding data aggregation, data enrichment and finally, data management and querying using Semantic Web technologies. Semantics are used in order to extract meaningful information from the sensor’s raw data and thus facilitate smart applications development over large-scale sensor networks.

The Symbiosis of Human and Semantic Technology Through the Lens of Actor-Network Theory
Background: Semantic technologies (STs) have made machine reasoning possible by providing intelligent data management methods. This capability has created new forms of interaction between humans and STs, which is called "semantic interaction." The increasing spread of this form of interaction in daily life reveals the need to identify the factors affecting it and introduce the requirements of...

متن کاملES3N: A Semantic Approach to Data Management in Sensor Networks
In this paper, we present a Data Management Tool called ES3N, which uses Semantic Web techniques to manage and query data collected from a minidome Sensor Network. Our tool supports complex queries on both continuous and archival data, by capturing important associations among data, collected and stored in a distributed dynamic ontology. The motivation behind our work stems from a desire to inc...
