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...

Grid is an environment that allows sharing of resources that are managed by diverse, independent administrative organizations that are geographically distributed. The main objective of grid is to enable users to solve problems using the available geographically distributed resources. To fully utilize these resources, effective discovery techniques are necessities. Grid resource discovery refers...

My general research interests lie in the area of distributed searching, overlay networking, and semantic web technologies. My thesis work is driven towards developing efficient and scalable resource discovery techniques for large-scale distributed systems, for example P2P networks and the Grid. Technological advances in the last decades, such as cheap computing power, high-volume data storage, ...

Resource brokering services are the main components that control the way applications are scheduled, managed and allocated in a decentralised, heterogeneous and dynamic Grid computing environment. Existing Grid computing systems such as a resource broker, e-Science application work-flow scheduler operate in tandem but still lack a coordination process that can lead to efficient application sche...

In this paper, cloud resource broker using goalbased request in medical application is proposed. To handle recent huge production of digital images and data in medical informatics application, the cloud resource broker could be used by medical practitioner for proper process in discovering and selecting correct information and application. This paper summarizes several reviewed articles to rela...

Metadata applications have developed local controlled vocabulary to meet information needs of users, but little is known about what vocabularies users use in searching for information. This paper reports the findings from an analysis of a digital library’s query log. The analysis addresses questions of to what extent users use controlled vocabulary in resource discovery and what non-controlled ...

This paper evaluates the performance in terms of resource consumption of a service discovery protocol proposed for heterogeneous Wireless Sensor Networks (WSNs). The protocol is based on a clustering structure, which facilitates the construction of a distributed directory. Nodes with higher capabilities are chosen to be clusterheads. We measure the energy and memory costs depending on the capab...

Service Discovery is an important step during the creation of distributed systems made out of independently developed and deployed quality-aware components. Despite of many prevalent approaches, the task of service discovery that encompasses components running on resource constrained devices does not yet have a satisfactory solution. Here, we present a service discovery framework which is speci...

Eficient and efiective discovery of resource and knowledge from the Internet has become an imminent research issue, especially with the advent of the Information Super-Highway. A multiple layered database (MLDB) approach is proposed to handle the resource and knowledge discovery in global information base. A preliminary experiment shows the advantages of such an approach. Information retrieval,...

Grids are likely to be the mainstay of distributed computing. Efficient resource discovery mechanism is one of the fundamental requirement for Grid computing systems. In this article we present a survey of recent work on the integration of multi-agent systems and peer-to-peer based resource discovery services for Grid systems. This discovery services would have several desirable features, inclu...
