A Call Admission Control Algorithm for WLAN in Heterogeneous Wireless Networks
One major challenge in the integration of wireless LAN (WLAN) and cellular networks is call admission control (CAC). Without a suitable CAC mechanism for the integrated network, the two networking systems will work independently and cannot simultaneously
Towards Understanding Complex Communication Networks: Performance, Phase Transitions and Control
Micro dynamics of large-scale communication networks is often described by a Markov process with a large number of locally interacting components. Due to astronomically high number of the Markov process states even for moderate-size networks, finding the
Common Industry Specification for Usability --Requirements
.The Common Industry Specification for Usability - Requirements (CISU-R) helps usability professionals, product managers, and others working in product design and development to create usability requirements. It sets standards for specifying usability
Real-Time Deployment of Multihop Relays for Range Extension
When the range of single-hop wireless communication is limited by distance or harsh radio propagation conditions, relays can be used to extend the communication range through multihop relaying. This paper targets the need in certain scenarios for rapid
3-D Segmentation and Motion Estimation of Range Data for Crash Prevention
In this paper we present a 3-D object segmentation and motion estimation scheme of range video data for crash prevention applications. The segmentation is based on slope values of every point in the scene with which atomic regions are constructed by region
Guidelines on Cell Phone Forensics
[Superseded by SP 800-101 Rev. 1 (May 2014): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=915021 ] Forensic specialists periodically encounter unusual devices and new technologies outside of traditional computer forensics. Cell phones are an
1310-nm Quantum Key Distribution System With Up-Conversion Pump Wavelength at 1550 nm
We show that the performance of a 1310-nm quantum key distribution (QKD) system with an up-conversion detector pumped at 1550 nm is comparable with or better than that of current 1550-nm QKD systems with 1310-nm pump detectors. The nonlinearly induced dark

Dielectric polarization evolution equations and relaxation times
In this paper we develop a model that can describe broadband dielectric response, and includes frequency-dependent loss and the effects of the local electric field. The model is based on a correlation-function approach that we previously developed using
Securing Radio Frequency Identification (RFID) Systems
Radio frequency identification (RFID) is a form of automatic identification and data capture technology that uses electric or magnetic fields at radio frequencies to transmit information. An RFID system can be used to identify many types of objects, such

Access Control Policy Combinations for the Grid Using the Policy Machine
Many researchers have tackled the architecture and requirements aspects of grid security, concentrating on the authentication or authorization mediation instead of authorization techniques, especially the topic of policy combination. Policy combination is
Quantum key distribution with high-speed superconducting single-photon detectors
We explore the potential of high-speed nanowire superconducting single-photon detectors for quantum key distribution in fiber, over long distances (at 1550 nm) and at high bit rates (at 850 nm).
Specification for the Extensible Configuration Checklist Description Format (XCCDF), Version 1.1.3
The Cyber Security Research and Development Act of 2002 tasks the National Institute of Standards and Technology (NIST) to "develop, and revise as necessary, a checklist setting forth settings and option selections that minimize the security risks
Specification-Driven Testing of Smart Card Interface Using a Formal Model
Model-Driven Engineering (MDE) is emerging as a promising approach that uses models to support various phases of system development lifecycle such as Code Generation and Verification/Validation (V &V). In this paper, we describe the application of a model
