Achieving Faster Access to Satellite Link Bandwidth

White Paper TCP with Van Jacobson Congestion Control (VJCC) is known to have poor performance over large bandwidth-delay product paths. TCP Performance Enhancing Proxies (PEPs) constitute one mechanism for ameliorating poor VJCC end-to-end... [19 Sep 2008]

Policy-Based Resource Management and Service Provisioning in GMPLS Networks

White Paper Emerging network applications tend to be built over heterogeneous network resources spanning multiple management domains. Many such applications have dynamic demands for dedicated, deterministic, high-bandwidth connections. [19 Sep 2008]

Photos: The bus that doesn't need a driver

Photo They have shown it controlling a platoon of passenger cars speeding along busy roads in Southern California, as well as running industrial vehicles such as snowplows and tractor trailers... [11 Sep 2008]

Computing Aggregates for Monitoring Wireless Sensor Networks

White Paper Wireless sensor networks involve very large numbers of small, low-power, wireless devices. Given their unattended nature, and their potential applications in harsh environments, the paper needs a monitoring... [11 Sep 2008]

Decentralized Utility-Based Sensor Network Design

White Paper Wireless sensor networks consist of energy constrained nodes operating typically in an unattended mode and highly dynamic environments. This paper advocates a systematic decentralized approach to designing these networks... [11 Sep 2008]

Practical Routing-Layer Support for Scalable Multihoming

White Paper The recent trend of rapid increase in routing table sizes at routers comprising the Internet's core is posing a serious challenge to the current Internet's scalability, availability, and stability. Multihoming is a prime... [04 Aug 2008]

Photos: Future car tech at the British Motor Show

Photo Around 200 FCXs have been built with selected customers currently testing them in Japan and southern California. This one has been developed by a team at the Cranfield University, which... [25 Jul 2008]

Architecture, Performance, and Scalability of a Real-Time Global Positioning System Data Grid

White Paper The current system processes 1 Hz position data from 85 stations in southern and central California. This paper describes the architecture of the real time SensorGrid system, which... [11 Jul 2008]

Generation of High Bandwidth Network Traffic Traces

White Paper High bandwidth network traffic traces are needed to understand the behavior of high speed networks (such as the Internet backbone). However, the implementation of a mechanism to collect such traces is... [11 Jul 2008]

Integrated Access Control and Intrusion Detection for Web Servers

White Paper Current intrusion detection systems work in isolation from access control for the application the systems aim to protect. The lack of coordination and inter-operation between these components prevents detecting and... [10 Jul 2008]

An Experimental Study of Localization Using Wireless Ethernet

White Paper This paper studies the use of wireless Ethernet (Wi-Fi) as a localization sensor for mobile robots. Wi-Fi-based localization relies on the existence of one or more Wi-Fi devices in the environment to act... [10 Jul 2008]

Flow-Through-Queue Based Power Management for Gigabit Ethernet Controller

White Paper This paper presents a novel architectural mechanism and a power management structure for the design of an energy-efficient Gigabit Ethernet controller. Key characteristics of such a controller are... [08 Jul 2008]

Collaborative Research on Web Dissemination of Geotechnical Data

White Paper Large quantities of data are consequently generated, much of them of interest and significant value to the broad geotechnical engineering and construction community as well as for... [03 Jul 2008]

A Portal for Access to Complex Distributed Information About Energy

White Paper Increasingly, federal, state and local Government need to make their information available to the online public. Frequently, though, there is too much data, it is in a variety of formats, and the data is only partly... [03 Jul 2008]

DGRC AskCal: Natural Language Question Answering for Energy Time Series

White Paper Even quite sophisticated users can experience difficulty navigating large collections of data to locate the answers to their queries. This paper describes AskCal, a system that employs natural language processing, an... [03 Jul 2008]
