Center node: "A Parameter-Based Approach to Resource Discovery in Grid Computing System"
  Abstract: A Grid system is essentially an infrastructure that allows location independent access to the resources and services that are provided by geographically distributed machines and networks. One of the fundamental operations needed to support location-independent computing is resource discovery. Generally, resource discovery schemes maintain and query a resource status database. Dissemination of the resource status information is one of the key operations required to keep the resource status databases consistent. This paper examines several approaches for resource status dissemination. A new concept called the Grid potential is introduced in this paper. This concept is used to control the extent of data dissemination in Grid systems.
