Weighted-HR: An Improved Hierarchical Grid Resource Discovery
Grid computing environments include heterogeneous resources shared by a large number of computers to handle the data and process intensive applications. In these environments, the required resources must be accessible for Grid applications on demand, which makes the resource discovery as a critical service. In recent years, various techniques are proposed to index and discover the Grid resource...
متن کاملNetwork Layer Resource Monitoring and Discovery for Information Service on Wireless Grids
1 This work was supported by the National Science Council, under Grant NSC 96-2628-E-009 -140 -MY3. Abstract—In grid computing, the grid information service (GIS) plays an important role in grid resource discovery, registry, and indexing. The resource monitoring and discovery service (MDS) in GIS provides a set of messages to get the status information of resource providers and keeps monitoring...
متن کاملResource discovery in modern computing environments
Resource discovery is an integral part of many kinds of computing environments, including emerging heterogeneous environments for pervasive computing. This paper characterises a number of current and future computing environments and summarises their resource discovery requirements. It then analyses, with respect to the requirements of each environment, several established service discovery pro...
متن کاملPeer-to-peer protocols and grid services for resource discovery on grids
Resource discovery is a key issue in Grid environments, since applications are usually constructed by composing hardware and software resources that need to be found and selected. Classical approaches to Grid resource discovery, based on centralized or hierarchical approaches, do not guarantee scalability in large-scale, dynamic Grid environments. On the other hand, the Peer-to-Peer (P2P) parad...
متن کاملFormalizing Service Publication and Discovery in Grid Computing Systems
Considering the autonomy of resources in the grid environment and based on the service-oriented thought, a resource management system for grid computing can be abstracted to a multi-agent system that consists of service requestor agents, service provider agents and service broker agents. For looking into the interaction characteristics of agents, the formal method is adopted. Firstly, we presen...
