Abstraction on sensor network and representation with a virtual layer
Yan Liu, Mei Chen · 2014
Research on sensor network has been focused at overcoming these deficiencies through more energy efficient routing, localization algorithms and system design. This paper tried to discuss some application related challenges, such as data integration, data storage, metadata generation, data fast query. We use analytical data management concept to create a virtual layer, which maps the real sensor network into abstract nodes through base nodes. This virtual layer helps applications use/reuse data from the sensor network, and provides functions including data acquisition, calculation, linkage, and broken management. This abstraction and virtual representation is shown with a web service (data integrity) for a building monitoring system.
