Towards Timely Intelligence in the Power Grid

February 25, 2013
Author(s)
YaShian Li-Baboud, Julien M. Amelot, Dhananjay Anand, Gerard N. Stenbakken, Thomas L. Nelson, James Moyne
One of the key lessons learned from the 2003 Northeast Blackout in the United States was the need for improved timing. The problem began as an isolated issue, but cascaded through the Northeastern grid. Timely situational awareness would likely have

Dynamic Key Refreshment for Smart Grid Mesh Network Security

February 24, 2013
Author(s)
Hamid Gharavi
This paper presents a dynamically updating key distribution strategy to enhance mesh network security against cyber attacks. The scheme has been applied to two security protocols known as Simultaneous Authentication of Equals (SAE) and Efficient Mesh

Virtual Reality Platform to Study RF Propagation in Body Area Networks

December 2, 2012
Author(s)
Kamran Sayrafian, John G. Hagedorn, Wen-Bin Yang, Judith E. Terrill
Design of efficient wireless communication protocols for body area networks requires in-depth understanding of the propagation media i.e. the human body. As obtaining large amount of data for many scenarios and use-cases via physical experiment is either

Wireless Network Deployment in the Smart Grid: Design and Evaluation Issues

November 30, 2012
Author(s)
Camillo A. Gentile, David W. Griffith, Michael R. Souryal
The projected use of the power grid for “smart” applications such as advanced metering and distributed automation will require highly reliable, secure, well-designed and managed communication networks. While many of the benefits of wireless communications

On Distributed Energy Routing Protocols in the Smart Grid

November 5, 2012
Author(s)
Jie Lin, Guobin Xu, David W. Griffith, Xinyu Yang, Wei Yu
The Smart Grid is a new type of power grid that will provide reliable, secure, and efficient energy transmission and distribution. It promises to integrate distributed energy resources with conventional generation plants, and intelligently transmit energy

Interference Mitigation Using Adaptive Schemes in Body Area Networks

September 30, 2012
Author(s)
Wen-Bin Yang, Kamran Sayrafian
Considering the medical nature of the information carried in Body Area Networks (BAN), interference from coexisting wireless networks or even other nearby BANs could create serious problems on their operational reliability. As practical implementation of

Factory Equipment Network Testing Framework: Concept, Requirements, and Architecture

September 17, 2012
Author(s)
James D. Gilsinn, Kang B. Lee, John L. Michaloski, Frederick M. Proctor, Yuyin Song
This document describes the purpose, concept, requirements, and architecture for the Factory Equipment Network Testing (FENT) Framework and the software to test equipment on real-time factory networks. Other documents contain more detailed information

Signal Processing Techniques for Smart Grid: Scanning the Issue

September 2, 2012
Author(s)
Hamid Gharavi
This is an editorial article for a special issue on Smart Grid. The main emphasis of this issue is the technical challenges of the Smart Grid from a signal processing perspective. Therefore, the selected articles aim at articulating signal processing

Testing Phasor Measurement Units using the IEEE 1588 Precision Time Protocol

July 1, 2012
Author(s)
Julien M. Amelot, Gerard N. Stenbakken
As the electric power grid is changing to a smarter more dynamically controlled system, there is increasing need for measurements that show the global status of the system for wide-area monitoring and control. These measurements require time

Wireless Networks for Smart Grid Applications

June 29, 2012
Author(s)
David W. Griffith, Michael R. Souryal, Nada T. Golmie
This chapter discusses the use of wireless networks in the context of the smart grid. First, it provides an overview of the various applications envisaged in the smart grid and discusses their communication requirements. Sifting through thousands of

Predicting Global Failure Regimes in Complex Information Systems

June 19, 2012
Author(s)
Christopher E. Dabrowski, James J. Filliben, Kevin L. Mills
Over the past five years, we investigated methods to characterize global behavior in large distributed systems and applied those methods to predict effects from deploying alternate distributed control algorithms. The methods we used assess global behaviors

Traffic Scheduling Technique for Smart Grid Advanced Metering Applications

June 5, 2012
Author(s)
Hamid Gharavi
In this paper, we present a multi-gate mesh network architecture that has been developed to ensure high performance and reliability under emergency conditions when a system expects to receive power outage notifications and exchanges. In order to handle the

Cloud Computing Synopsis and Recommendations

May 29, 2012
Author(s)
Mark L. Badger, Timothy Grance, Robert Patt-Corner, Jeffrey M. Voas
This document reprises the NIST-established definition of cloud computing, describes cloud computing benefits and open issues, presents an overview of major classes of cloud technology, and provides guidelines and recommendations on how organizations

LDPC Error Correction in the Context of Quantum Key Distribution

April 23, 2012
Author(s)
Anastase Nakassis
Secret keys can be established through the use of Quantum channels monitored through classical channels which can be thought of as being error free. Because many of the feasible implementation of the quantum channel are subject to erasures –often massive-
