An important aspect of managing service-oriented grid environments is management of agreement relationships between service providers and their customers. The key concept in addressing these agreements is service level agreement. In this paper we motivate the need for SLA lifecycle management in services grid and present results of our analysis on functional and non-functional requirements. Aft...

This paper outlines the design and implementation of Grid-HSI, a Service Oriented Architecturebased Grid application to enable hyperspectral imaging analysis. Grid-HSI provides users with a transparent interface to access computational resources and perform remotely hyperspectral imaging analysis through a set of Grid services. Keyword: Grid computing, portal grid, remote sensing, image process...

Grid technologies and infrastructures facilitate distributed resource sharing and coordination in dynamic, heterogeneous, multi-institutional environments. A replica catalog is a Grid component that keeps replica locations of data objects and provides location transparency to data access. Replica selection is of great importance to data-intensive scientific computing targeted by many data Grid ...

Resource brokering is a crucial activity in Grid infrastructures and other environments with dynamic resource selection. The mediation between resource requirements and available resources relies on adequate resource description, which becomes a special challenge when the resources are (Grid) services. In addition to the description of service semantics, service quality is another useful select...

The diversity of grid service originates from heterogeneous and dynamic nature of grid, and it poses a great challenge to grid service discovery. How to discover services satisfying users’ multiple requests meanwhile avoiding negative effect derived from requests and updates becomes increasingly important in grid environment. This paper proposes a Cross-VO (Visual Organization) service domain m...

It is publicly considered that the next generational Internet technology is grid computing, which supports the sharing and coordinated use of diverse resources in dynamic virtual organizations from geographically and organizationally distributed components. Grid computing characters strong computing ability and broad width information exchange[1]. Globus presented Open Grid Services Architectur...

Location service provides position of mobile destination to source node to enable geo-routing. In existing quorum-based location service protocols, destination node registers its location along a ‘column’ while source node makes a query along a ‘row’. Grid and quorumbased location service is based on division of network into square grids, and selecting ‘leader’ location server node in each grid...

Grid computing has become an important new research field. The goal of the Grid computing infrastructure is to pervasively access the computational resources available on the Internet. The web service technology has the potential to achieve the goal of grid computing because of its self-contained, self-describing, and loosely coupled features. The resources can be discovered and shared through ...

As Grid computing becomes more and more practical, User needs a steady computing environment and an effective way to assemble simple services into complicated service to meet their requirements. Based on BPEL4WS, this paper introduces a Grid Job Description Language (GJDL) to combine correlation services into composited service. With GJDL, we design and implement a job support system which has ...

In this article we examine the integration three emerging trends in Information Technology (Utility Computing, Grid Computing, and Web Services) new Computing paradigm (Grid-based Application Service Provision) that is taking place in the context the European research project GRASP. In the first of the paper, we explain how the integration of emerging trends can support enterprises in creating ...
