Instruments and sensors supported by e-Infrastructure
Presented by Mr. Norbert MEYER on 14 Apr 2010 from 11:20 to 11:40
Track: End-user environments, scientific gateways and portal technologies
The introduction gives the major objectives and the idea of instrument and sensor remote steering, controlling and monitoring. The second part presents the user experiences and requirements following a proposition of the general architectural framework. The way of integrating instrumention with existing e-Infrastructure is especially important for the ESFRI projects, where most are using some equipment for data capturing and computing resources for further simulations.
The presentation will explore the e-Infrastructure requirements of experimental scientists and will provide an overview of the current projects involved in the field. The major goal is to demonstrate a prototype system developed by the project DORII (www.dorii.eu). Although the results are addressed to scientists who are using expensive equipment, the authors plan to use the same approach to control small devices and sensors which are used in future Internet technologies. The most obvious advantage of this approach is that one can exploit the storage and processing capabilities that the classical data and computing ecosystem offers. By representing the instrument as a service and integrating it with other services through well-understood protocols, it becomes straightforward to directly store experimental data to arbitrary locations world-wide, replicate them in multiple locations, and perform post-processing, that previously took days or months, in only a fraction of the time.
The architecture proposed by the DORII project allows to integrate various type of applications, which daily use instruments to collect data. The data are used for further analysis and simulations. The natural integration is to have a unified infrastructure including sensors, instruments, grid, visualisation and data repositories. This is permitted by the DORII framework. It is worth mentioning that nearly all ESFRI communities are using some instruments, and the goal of these communities is the better use of the existing infrastructure.
The DORII community is aiming in the near future to define some ESFRI related use cases, and to adopt the current architecture for their needs.
