Tinydb: An acquisitional query processing system for sensor networks

by Samuel R. Madden, Michael J. Franklin, Joseph M. Hellerstein, Wei Hong - ACM Trans. Database Syst , 2005
"... We discuss the design of an acquisitional query processor for data collection in sensor networks. Acquisitional issues are those that pertain to where, when, and how often data is physically acquired (sampled) and delivered to query processing operators. By focusing on the locations and costs of acq ..."

, and execution. We evaluate these issues in the context of TinyDB, a distributed query processor for smart sensor devices, and show how acquisitional techniques can provide significant reductions in power consumption on our sensor devices.

Implementation and performance of Munin

by John B. Carter, John K. Bennett, Willy Zwaenepoel - IN PROCEEDINGS OF THE 13TH ACM SYMPOSIUM ON OPERATING SYSTEMS PRINCIPLES , 1991
"... Munin is a distributed shared memory (DSM) system that allows shared memory parallel programs to be executed efficiently on distributed memory multiprocessors. Munin is unique among existing DSM systems in its use of multiple consistency protocols and in its use of release consistency. In Munin, sha ..."

Rumor Routing Algorithm for Sensor Networks

by David Braginsky, Deborah Estrin , 2002
"... Advances in micro-sensor and radio technology will enable small but smart sensors to be deployed for a wide range of environmental monitoring applications. In order to constrain communication overhead, dense sensor networks call for new and highly efficient methods for distributing queries to nodes ..."

that have observed interesting events in the network. A highly efficient data-centric routing mechanism will offer significant power cost reductions [17], and improve network longevity. Moreover, because of the large amount of system and data redundancy possible, data becomes disassociated from specific

Single-ISA Heterogeneous Multi-Core Architectures: The Potential for Processor Power Reduction

by Rakesh Kumar, Keith I. Farkas, Norman P. Jouppi, Parthasarathy Ranganathan, Dean M. Tullsen , 2003
"... This paper proposes and evaluates single-ISA heterogeneous multi-core architectures as a mechanism to reduce processor power dissipation. Our design incorporates heterogeneous cores representing different points in the power/performance design space; during an application 's execution, system s ..."

Digital libraries and autonomous citation indexing

by Steve Lawrence, C. Lee Giles, Kurt Bollacker - IEEE COMPUTER , 1999
"... The World Wide Web is revolutionizing the way that researchers access scientific information. Articles are increasingly being made available on the homepages of authors or institutions, at journal Web sites, or in online archives. However, scientific information on the Web is largely disorganized. T ..."

provide significant advantages over traditional citation indices. No manual effort is required for indexing, which should result in a reduction in cost and an increase in the availability of citation indices. An ACI system can also provide more comprehensive and up-to-date indices of the literature

Citeseer: an automatic citation indexing system

by C. Lee Giles, Kurt D. Bollacker, Steve Lawrence - INTERNATIONAL CONFERENCE ON DIGITAL LIBRARIES , 1998
"... We present CiteSeer: an autonomous citation indexing system which indexes academic literature in electronic format (e.g. Postscript files on the Web). CiteSeer understands how to parse citations, identify citations to the same paper in different formats, and identify the context of citations in the ..."
Abstract - Cited by 292 (46 self) - Add to MetaCart
in the body of articles. CiteSeer provides most of the advantages of traditional (manually constructed) citation indexes (e.g. the ISI citation indexes), including: literature retrieval by following citation links (e.g. by providing a list of papers that cite a given paper), the evaluation and ranking

ACKNOWLEDGMENTS

On the Performance of Ad Hoc Networks with Beamforming Antennas

by Ram Ramanathan - ACM MobiHoc , 2001
"... Beamforming antennas have the potential to provide a fundamental breakthrough in ad hoc network capacity. We present a broad-based examination of this potential, focusing on exploiting the longer ranges as well as the reduced interference that beamforming antennas can provide. We consider a number o ..."

Automated Consistency Checking of Requirements Specifications

by Constance L. Heitmeyer, Ralph D. Jeffords, Bruce G. Labaw , 1996
"... This paper describes a formal analysis technique, called consistency checking, for automatic detection of errors, such as type errors, nondeterminism, missing cases, and circular definitions, in requirements specifications. The technique is designed to analyze requirements specifications expressed i ..."
