Resource discovery is one of the most important services that significantly affects the efficiency of grid computing systems. The inherent dynamic and large-scale characteristics of grid environments make their resource discovery a challenging task. In recent years, different approaches have been proposed for resource discovery, attempting to tackle the challenges of grid environments and impro...

The resource discovery problem poses new challenges in infrastructure-less wireless networks. Due to the highly dynamic nature of these networks and their bandwidth and energy constraints, there is a pressing need for energy-aware communicationefficient resource discovery protocols. This chapter provides an overview of several approaches to resource discovery, discussing their suitability for c...

Networks of the future will be characterized by a variety of computational devices that display a level of dynamism not seen in traditional wired networks. Because of the dynamic nature of these networks, resource discovery is one of the fundamental problems that must be solved. While resource discovery systems are not a novel concept, securing these systems in an efficient and scalable way is ...

Efficient Resource discovery mechanism is one of the fundamental requirement for Grid computing systems, as it aids in resource management and scheduling of applications. Resource discovery activity involve searching for the appropriate resource types that match the user’s application requirements. Various kinds of solutions to grid resource discovery have been suggested, including the centrali...

Resource discovery is a core function of e-learning. While initially confined to library environments, it has become pervasive, partly due to the advent of web-based searching and also service-oriented approach. The latter is the focus of this paper as resource discovery (web) services enable existing resources to be identified from a source (library) and re-purposed for educational purposes in...

It is an ongoing debate whether categorical systems created by some experts are an appropriate way to help users finding useful resources in the internet. However for the much more restricted domain of language documentation such a category system might still prove reasonable if not indispensable. This article gives an overview over the particular IMDI category set and presents a rough evaluati...

Large scale computer networks provide access to a bewilderingly large number and variety of resources, including retail products, network services, and people in various capacities. We consider the problem of allowing users to discover the existence of such resources in an administratively decentralized environment. We describe an approach for a system that accesses the distributed collection o...
