The growing ubiquity of sophisticated sensor/actuator devices with embedded computing and communications capabilities, and the emergence of pervasive information and computational Grids require a middleware infrastructure that: (a) is scalable and self-managing, (b) is based on content rather than names and/or addresses, (c) supports asynchronous and decoupled interactions rather than forcing s...

The quantification of interdependencies is a major challenge when attempting to analyze the behavior of critical infrastructures. This paper presents a taxonomy of interdependency quantification metrics based on their information content, decision support and risk analysis capabilities, and computational costs. The paper also discusses a systematic approach for computing metrics and performance...

Yahoo! is building a set of scalable, highly-available data storage and processing services, and deploying them in a cloud model to make application development and ongoing maintenance significantly easier. In this paper we discuss the vision and requirements, as well as the components that will go into the cloud. We highlight the challenges and research questions that arise from trying to buil...

The Federal Aviation Administration (FAA) is seeking to develop alternative position navigation and timing (APNT) systems in order to minimize the impact of a degradation of the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS). The developed APNT system needs to have capabilities beyond those provided by currently existing FAA ground based navigation aids are...

Unbundling consists in the possibility for a new operator of having special access to the incumbent’s network infrastructure, in order to provide value-added services without the necessity to duplicate the infrastructure itself. Access network unbundling has received most attention in Europe. Most European operators are interested mainly in the physical access to copper loop, which gives the op...

Decisions to invest in information technology (IT) infrastructure are often made based on an assessment of its immediate value to the organization. However, an important source of value comes from the fact that such technologies have the potential to be leveraged in the development of future applications. From a real options perspective, IT infrastructure investments create growth options that ...

The confluence of technological advances in wireless technology, mobile computing, novel displays, and sensors in addition to the decreasing cost of computing power provides the opportunity for utilizing computational capabilities in an increasing number of specialized, yet networked devices. By integrating and embedding these devices into “smart spaces,” we have the opportunity to move computi...

Future shop-floors are going to evolve as they need to be able to fully respond to dynamic adaptations and sophisticated interactions with the enterprise systems. This trend is fully backed up by the ever increasing capabilities of the new generation of devices that feature advanced communication as well as computational capabilities. However as the transition to the future infrastructure will ...

The FARGOS/VISTATM suite of technologies implements an infrastructure for the development, deployment and non-stop operation of transparently distributed, multithreaded, architecture-neutral, object-oriented peer-topeer applications. These capabilities can be applied in a variety of paradigms, ranging from simple client/server applications to more sophisticated applications that are dynamically...

1.0 Introduction Recent years have seen an increase in the number of devices with differing communication, compute and display capabilities. Increasingly, services need to interact with a wide spectrum of devices with varying networking capabilities. In most cases, services and the functions that they perform are independent of the transports deployed for communications. Furthermore, given the ...
