Hierarchical Restoration Scheme for Multiple Failures in GMPLS Networks
It is expected that GMPLS-based recovery could become a viable option for obtaining faster restoration than layer 3 rerouting. Even though dedicated restoration ensures restorability of connections, exclusive use of dedicated scheme would result in wasting
The Effect of Delay Mismatch in MPLS Networks Using 1+1 Protection
High-capacity optical-fiber backbone networks protect information flows belonging to their premium customers by routing two copies of the customer's data over disjoint paths. This scheme, known as 1+1 protection, ensures that the customer will experience
Bluetooth Dynamic Scheduling and Interference Mitigation
Bluetooth is a cable replacement technology for Wireless Personal Area Networks. It is designed to support a wide variety of applications such as voice, streamed audio and video, web browsing, printing, and file sharing, each imposing a number of quality
Vulnerabilities in Quantum Key Distribution Protocols
Policy Expression and Enforcement for Handheld Devices
The use of mobile handheld devices, such as Personal Digital Assistants (PDAs) and tablet computers, within the workplace is expanding rapidly. These devices are no longer viewed as coveted gadgets for early technology adopters, but instead have become
The NIST Microforce Realization and Measurement Project
The National Institute of Standards and Technology (NIST) has launched a five-year Micro-force Realization and Measurement project focusing on the development of an instrument and laboratory capable of realizing and measuring the SI unit of force below
COTS Security Protection Profile - Operating Systems (CSPP-OS) (Worked Example Applying Guidance of NISTIR-6462, CSPP) Version 1.0
CSPP-OS provides a worked example of the guidance in NISTIR-6462 for the development of Common Criteria Protection Profiles for commercial off the shelf (COTS) information technology. The intended audience consists of those individuals and organizations in

Decoherence of a Superconducting Qubit due to Bias Noise
We calculate for the current-biased Josephson junction the decoherence of the qubit state from noise and dissipation. The effect of dissipation can be entirely accounted for through a noise model of the current bias that appropriately includes the effect
Spotlight - Biometric Authentication -- Are You Who You Claim To Be?
The recent establishment of the International Organization for Standardization/International Electrotechnical Commission Joint Technical Committee 1/Subcomittee 37 (ISO/IEC JTC 1/SC 37) on Biometrics is a major development in international standardization
Self-Adaptive Leasing for Jini
Distributed computing environments require strategies by which components can detect and recover from failures in remote, collaborating components. Many protocols for distributed systems employ a strategy based on leases, which grant a leaseholder with
Joint Distribution of Link Distances
The calculation of two-hop connectivity between two terminals for randomly deployed wireless networks requires the joint probability distribution of the distances between these terminals and the terminal that is acting as a relay. In general the distances
Expected Multi-Hop Power Consumption in Mobile Ad-Hoc Networks
Mobile Ad-Hoc Networks provide the means to reduce significantly the power required for routing from source to destination through multi-hops between other nodes in the network. In the presence of mobility, only continuous updating can guarantee routes
A Cognitive Framework for Performance/Resilience Optimized Multipath Routing in Networks with Unstable Topologies
This paper proposes a framework for optimized multipath routing in a wireless network with frequently changing topology. The topology changes may be due to node mobility in mobile ad hoc networks, or limited node reliability and power supply in sensor
Biometric Standards -- A Key to a More Secure World
Biometric technologies are becoming the foundation of an array of highly secure identification and verification solutions. Over the past eighteen months, the U.S has quickly worked to establish formal standards groups for accelerating and harmonizing the

Understanding the Correlation Structure of Network Traffic
This paper aims to improve current understanding of the correlation structure of traffic carried over large networks, such as the Internet. To achieve this aim we use simulation, adopting a methodology of homogenization to achieve a sufficiently large
