The Semantic Grid refers to an approach to Grid computing in which information, computing resources and services are described using the semantic data model. In this model the data and metadata are expressed through facts (small sentences). Therefore it becomes directly understandable for humans. This makes it easier for resources to be discovered and joined up automatically, which helps bring resources together to create virtual organizations. The descriptions constitute metadata and are typically represented using the technologies of the Sema ....etc

ROUTE STABILITY IN MANETS UNDER THE RANDOM DIRECTION MOBILITY MODEL -- MOBILE COMPUTING

A fundamental issue arising in mobile ad hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this work, we study both the availability and the duration probability of a routing path that is subject to page link failures caused by node mobility. In partic ....etc

A Computational Grid is a collection of heterogeneous computers and resources spread across multiple administrative domains with the intent of providing users easy access to these resources. There are many ways to access the resources of a Computational Grid, each with unique security requirements and implications for both the resource user and the resource provider.

A comprehensive set of Grid usage scenarios is presented and analyzed with regard to security requirements such as authentication, authorization, integrity, and confidentiality ....etc

GEMINI (Generic Monitoring Infrastructure) is a lightweight
framework for providing monitoring data of various types over
Web Services in distributed environments. GEMINI can collect
data about different types of entities including applications,
resources or services. Generic sensor infrastructure is provided
to enable users to create and deploy their own sensors and produce
data into GEMINI infrastructure. In the design of GEMINI we have
combined lightweight technologies with web services to provide
both: efficiency and interoperabilit ....etc

Abstract:
Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. It moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. This unique paradigm brings about many new security challenges, which have not been well understood. This work studies the problem of ensuring the integrity of data storage in Cloud Computing. In particular, we consider the task of allowing a third party aud ....etc

1. Introduction
The last decade has seen a substantial increase in commodity computing and network performance, mainly as a result of faster hardware and more sophisticated software. These commodity technologies have been used to develop low-cost high-performance computing systems, popularly called clusters, to solve resource-intensive problems in a number of application domains. Particularly, in the scientific arena, the availability of powerful computing resources has allowed scientists to broaden their simulations and e ....etc
