Grid computing is becoming a research focus in distributed and parallel systems. The idea of the grid service being a kernel of the whole grid architecture is accepted by the researchers. The grid service has the characteristics of high scalability and dynamic. By analyzing the resource management in heterogeneous environment and agent-based hierarchy model, this paper presents an agent-based d...

Mobile Grid Service is the extension of Grid Service. It is defined as: it is an intelligent code service wandering in grid nodes to accomplish certain task and provide certain service. Mobile Grid Service provides a series of standard interfaces and conforms specific conventions to solve such problems as: mobile service discovery, dynamic service creation, lifetime management, notification, mo...

Service-oriented grid is a type of grid environment which makes extensive use of existing and emerging standards from all segments of the Web service community. Ontology, as a knowledge representation tool, can normally be used to semantically represent such type of grid. However, knowledge representation of a grid environment is not an easy task since the concept of grid covers many computing ...

Grid Computing [1, 2] has gained a huge momentum not only in the scienti c community but also in industrial application areas. The technology itself has evolved from proprietary, specialized applications and middleware to the adoption of web service standards [3, 4]. Service-oriented Grid environments o er the possibility to request and use computing power, data access, network bandwith and spe...

Emerging urgent computing tools can quickly allocate computational resources for the execution of time critical jobs. Grid applications and workflows often use Grid services and service-oriented architectures. Currently, urgent computing tools cannot allocate or manage Grid services. In this paper, we evaluate a service-oriented approach to Grid service access and provisioning for urgent comput...

Information Service is a key component of a Grid environment and crucial to the operation of a computational Grid. This paper presents an Information Service for a computational Grid Virtual Organization (VO). The main functionality of this Information Service is the provision of information essential for applications running on a computational Grid. This Information Service is a hierarchical s...

Nowadays, Grid Computing has been accepted as an infrastructure to perform parallel computing in distributed computational resources. Grid has users, resources, and an information service (IS). Resource broker service is one of the main services in grid to find resources, filter resources, allocate resources, etc. Resource selection is part of resource broker that is an important issue in a gri...

Grid computing provides a robust paradigm to aggregate disparate resources in a secure and controlled environment. Grid architectures require an underpinning Quality of Service (QoS) support in order to manage complex data and computation intensive applications. However, QoS guarantees in the Grid context have not been given the attention they merit. In order to enhance the functionality offere...

Currently, the grid computing community is undergoing a paradigm shift from the traditional resource-centric model to a service-oriented one. The Open Grid Services Architecture (OGSA) from the Global Grid Forum proposes that Web service-like abstractions be used to encapsulate shared grid resources for service-oriented grid computing. An important management component of such an infrastructure...
