Resource discovery is one of the most important services affecting grid performance. Because of inherent characteristics of grid environments such as heterogeneity, dynamicity and scalability, usually grid resource discovery approaches deal with some challenges to be efficient. One of the most important challenges is reliability and stability of resource discovery in grid environment. The main ...

This paper proposes a simple and scalable web-based model for grid resource discovery for the Internet. The resource discovery model contains the metadata and resource finder web services. The information of resource finder web services is kept in the repositories that are distributed in the application layer of Internet. The resource finder web services will be discovered by sending queries to...

The resource discovery mechanism is a hot topic issue in grid environments and It has great impact on the efficiency of the resource sharing and cooperative computing. Based on the domain and resource routing nodes, a grid resource discovery model of multilayer overlay network was given in this paper. And on this basis, using a linear combination of the block distance and chessboard distance in...

In computational grids, heterogeneous resources with different ownerships are dynamically available and distributed geographically. Resource discovery is one of the most important services of grid computing. Resource Discovery service provides mechanisms to identify the set of resources that are capable of satisfying the job requirements. It is not realistic to build the resource discovery mech...

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...

Resource discovery in a Grid environment is a critical problem and also a fundamental task which provides searching and locating necessary resources for given processes. Based on the domain and resource routing nodes, a grid resource discovery model of multilayer overlay network is given in this paper. And on this basis, using a linear combination of the block distance and chessboard distance i...

Automatic Grid resource discovery and brokerage shields the Grid middleware complexities from the Grid users and leads towards an invisible but simple and robust Grid. Realizing this vision requires a machine understandable resource description and powerful correlation 1 mechanism. Semantic technologies like ontologies provide vocabularies with explicitly defined, unambiguously understandable a...

In this chapter, we will address the problem of resource discovery that ensures sustained QoS (Quality of Service) for mobile applications. We present two aspects of the resource discovery problem: (i) static resource discovery that determines the best resources to service a request when it is initiated, (ii) dynamic resource reprovisioning that continues to find nearby resources as a mobile cl...
