GRAIL – A Tool for Accessing and Instrumenting WSRF–compliant Web Services
"... Grid access methods are still dominated by command line tools or manually developed, problem specific graph-ical user interfaces. This fact reduces the acceptance of the Grid for users, who are not familiar with the usage of the Linux shell or the Grid itself. The first step away from the command li ..."

Policy-driven Negotiation for Authorization in the Grid
"... Abstract — In many Grid services deployments, the clients and servers reside in different administrative domains. Hence, there is a requirement both to discover each other’s authorization policy, in order to be able to present the right assertions that allow access, and to reveal as little as possib ..."

Furthermore, we present an implementation of a prototype, based on the PEERTRUST policy language and its reasoning engine, that is integrated in the Web services runtime component of the Globus Toolkit. The negotiation process is facilitated through the implementation of WSRF-compliant

The physiology of the grid: An open grid services architecture for distributed systems integration
, 2002
"... In both e-business and e-science, we often need to integrate services across distributed, heterogeneous, dynamic “virtual organizations ” formed from the disparate resources within a single enterprise and/or from external resource sharing and service provider relationships. This integration can be t ..."

platform facilities. The Open Grid Services Architecture also defines, in terms of Web Services Description Language (WSDL) interfaces and associated conventions, mechanisms required for creating and composing sophisticated distributed systems, including lifetime management, change management
Systems Competition and Network Effects
- JOURNAL OF ECONOMIC PERSPECTIVES—VOLUME 8, NUMBER 2—SPRING 1994—PAGES 93–115
, 1994
"... Many products have little or no value in isolation, but generate value when combined with others. Examples include: nuts and bolts, which together provide fastening services; home audio or video components and programming, which together provide entertainment services; automobiles, repair parts and ..."

photographic services. These are all examples of products that are strongly complementary, although they need not be consumed in fixed proportions. We describe them as forming systems, which refers to collections of two or more components together with an interface that allows the components to work together
A Delay-Tolerant Network Architecture for Challenged Internets
, 2003
"... The highly successful architecture and protocols of today’s Internet may operate poorly in environments characterized by very long delay paths and frequent network partitions. These problems are exacerbated by end nodes with limited power or memory resources. Often deployed in mobile and extreme env ..."

environments lacking continuous connectivity, many such networks have their own specialized protocols, and do not utilize IP. To achieve interoperability between them, we propose a network architecture and application interface structured around optionally-reliable asynchronous message forwarding, with limited
The anatomy of the Grid: Enabling scalable virtual organizations.
- The International Journal of High Performance Computing Applications
, 2001
"... Abstract "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation. In this article, we define this new field. First, ..."

Versatile Low Power Media Access for Wireless Sensor Networks
, 2004
"... We propose B-MAC, a carrier sense media access protocol for wireless sensor networks that provides a flexible interface to obtain ultra low power operation, effective collision avoidance, and high channel utilization. To achieve low power operation, B-MAC employs an adaptive preamble sampling scheme ..."

B-MAC supports on-the-fly reconfiguration and provides bidirectional interfaces for system services to optimize performance, whether it be for throughput, latency, or power conservation. We build an analytical model of a class of sensor network
