Peer-to-peer organization of Grid resource discovery services would have several desirable features, including high scalability, high reliability, self-organization and self-healing. In this paper, we describe challenges in applying P2P techniques to Grid services. These include the choice of overlay configuration and varying security requirements for Grid and P2P environments. We present the d...

This paper presents GODIS (Grid Ontological Directory and Integration System) a comprehensive architecture for resource sharing and discovery in large-scale grids, where nodes integrate local ontologies to expand semantic knowledge of shared grid resources. A peer-to-peer based DHT overlay is used to facilitate the formation of semantic communities on a large scale. Inside communities, ontologi...

A new methodology is presented in this paper for resource management in a metacomputing environment using a hierarchy of homogeneous agents that has the capability of service discovery. The PACE [6] tools are used to provide quantitative data concerning the performance of sophisticated applications running on local high performance resources. At metacomputing level, an agent hierarchy is used t...

This document addresses the issues of the discovery of URN (Uniform Resource Name) resolver services that in turn will directly translate URNs into URLs (Uniform Resource Locators) and URCs (Uniform Resource Characteristics). The document falls into three major parts, the assumptions underlying the work, the guidelines in order to be a viable Resolver Discovery Service or RDS, and a framework f...

The proliferation of mobile computing devices including laptops, personal digital assistants (PDAs), and wearable computers has created a demand for wireless personal area networks (PANs). PANs allow proximal devices to share information and resources. The mobile nature of these devices places unique requirements on PANs, such as low power consumption, frequent make-and-break connections, resou...
