Abstract

Spatial Data Grid is an ideal environment to handle the data-intensive and computing-intensive geo-spatial processes. In this heterogeneous and distributed environment, the requirements of service scheduling are dynamic and diverse. Therefore, an appropriate scheduling mechanism should be adopted, which would be able to deal with the resources properties of a grid environment, such as the data size, network capabilities, and the capabilities of processors, and meet the need of specific GIS (Geographic Information System) applications. This paper proposes a scheduling mechanism based on utility of Quality of Service (QoS). And, this scheduling mechanism, wrapped into a standard WSRF service, provides a transparent way to select the appropriate spatial data service providers in a dynamic spatial data grid and hides the complexity of the scheduling strategy from users to coordinate those required services. Experiments show that our scheduling mechanism can provide services selection and performance guarantees and lead to better spatial resource sharing and significant service performance.
