Abstract
This paper studies a resource discovery scheme for a Grid system comprised of virtual organizations (VOs). The proposed scheme suggests that routers and resources comprise VOs within a Grid system, where a router controls locally a number of resources. The router also maintains the connections of each VO with other VOs in the system. Each VO acquires only partial/limited knowledge of the availability of resources controlled by other VOs in the system. When a request for a specific resource is created in a VO of the system, the goal is to discover an appropriate resource for its satisfaction, and subsequently to effectively direct this request. The proposed resource discovery scheme takes into consideration the fact that VOs only acquire a limited knowledge of the system and manages to extend this knowledge without affecting negatively the satisfaction of requests. During the satisfaction of requests, the proposed resource discovery scheme supports and enhances the VOs of the system in order to gain better knowledge of the Grid resource availability. As the creation and satisfaction of requests progress, the VOs manage to acquire an adequate knowledge of the Grid resources, enhancing the overall system's well-function. Finally, this paper presents the performance evaluation of the resource discovery scheme by providing a number of simulation tests in Grid systems of different sizes.
