Vector Corrected Noise Temperature Measurements
A new one-port noise temperature measurement technique is presented that uses receiver noise parameters for error correction. Improved accuracy in one-port noise temperature measurements made with commercial systems is demonstrated without using isolators
Simulations of Noise-Parameter Uncertainties
This paper reports results for uncertainties obtained using a Monte Carlo simulation of noise-parameter measurements. The simulator permits the computation of the dependence of the uncertainty in the noise parameters on uncertainties in the underlying
Video Transmission for 3G Mobile Communication Systems
This paper presents the design and implementation of a mobile ad-hoc network for video communications. The network architecture is based on cluster-to-cluster operation using IEEE 802.11b FHSS (Frequency Hopping Spread Spectrum). FHSS is considered to
Modeling CPU Demand in Heterogeneous Active Networks
Active-network technology envisions deployment of virtual execution environments within network elements, such as switches and routers. As a result, application-specific processing can be applied to network traffic. To use such technology safely and
Measuring the Impact of Information on Complex Systems
The application of power-driven machinery to manufacturing and other areas of human endeavor characterized the Industrial Revolution in the 18th and 19th centuries. Measurement contributed in many ways to the increasing economic influence of these machines
IEEE Standard 802.16: A Technical Overview of the WirelessMAN TM Air Interface for Broadband Wireless Access
The broadband wireless access industry, which provides high-rate network connections to stationary sites, has matured to the point at which it now has a standard for second-generation wireless metropolitan area networks. IEEE Standard 802.16, with its
Contingency Planning Guide for Information Technology Systems
This ITL Bulletin summarizes NIST SP 800-34, Contingency Planning Guide for Information Technology Systems. It describes the process of developing contingency plans, procedures, and technical measures that can enable a system to be recovered quickly and
Contingency Planning Guide for Information Technology Systems
Kinetic Spanning Trees for Minimum-Power Routing in MANETS
A distributed kinetic spanning tree algorithm is proposed for routing in wireless mobile ad hoc networks. Assuming a piecewise linear motion model for the nodes, the sequence of shortest-path spanning trees is determined, valid until the time of the next
Hyperborders in the Voronoi-Diabram-Based Neural Net for Pattern Classification
We propose a neural network to answer a point query in Rn partitioned based on the Voronoi diagram. Our novel design offers the potential to reduce both the number of neurons and connection weights of previous designs, employing a cost function which
Comulative Acknowledgement Multicast Repetition Policy for Wireless LANs or Ad Hoc Network Clusters
For a wireless LAN or a cluster of nodes in an ad hoc wireless network, multicast transmissions from a controlling station must be acknowledged by the nodes that are addressed. To ensure reliable reception at all the nodes, the multicast packet may be
Video Transmission for Multi-Hop Networks Using IEEE 802.11 FHSS
In many applications such as construction, manufacturing, ground robotic vehicles, and rescue operations, there are many issues that necessitate the capability of transmitting digital video and that such transmissions should be performed wirelessly and in
Video Communications Via Multihop Ad-Hoc Networks: Design and Implementation
This paper presents the design and implementation of a mobile ad-hoc network for video communications. The network architecture is based on cluster-to-cluster operation using IEEE 802.11b FHSS (Frequency Hopping Spread Spectrum). FHSS is considered to

Dynamic Expansion of M:N Protection Groups in GMPLS Optical Networks
In order to provide reliable connections across metropolitan and wide-area optical networks, the network operator must provide some degree of redundancy so that traffic can be switched from damaged working paths to backup paths that are disjoint from the
Techniques for System and Data Recovery
The key asset in Federal agencies today is the information and data used to implement, sustain and maintain critical government programs and operations. Current efforts in ensuring that the United States can recover and restore activities which have great
QoS Routing Under Adversarial Binary Uncertainty
A cost-based admission control and routing scheme admits an arriving request on the minimum cost route if this cost does not exceed the cost of the request, and rejects the request otherwise. Cost based strategies naturally arise as a result of
