A Survey of Self-Organization in Wireless Networks

January 1, 2007
Author(s)
Kevin L. Mills
This paper surveys recent research on self-organizing techniques applied to design and control large wireless ad hoc and sensor networks. The survey divides that research into five functional categories: (1) resource sharing, (2) structure formation and

Investigating Global Behavior in Computing Grids

September 1, 2006
Author(s)
Kevin L. Mills, Christopher E. Dabrowski
This paper presents an executable model of grid computing systems and a measurement approach, based on multidimensional analysis, to understand global behavior in a complex system. Specifically, we investigate effects of spoofing attacks on the scheduling

A Cross-Correlation Based Method for Spatial-Temporal Traffic Analysis

October 1, 2005
Author(s)
Kevin L. Mills, Y. L. Jiang
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

A Model-Based Analysis of First-Generation Service Discovery Systems

October 1, 2005
Author(s)
Christopher E. Dabrowski, Kevin L. Mills, Stephen Quirolgico
Future commercial software systems will be based on distributed service-oriented architectures in which applications are composed dynamically from remote components. A key part of service-oriented computing is the ability for clients to discover remote

DNSSEC Test and Measurement Tools: Secure Zone Integrity Tester v0.9.3, Zone Monitoring Tool v0.9, dns Trace : traffic statistics collection tool, querysim : DNS query workload monitoring tool

October 1, 2005
Author(s)
Scott W. Rose, Darrin J. Santay, Douglas Montgomery, Kevin L. Mills, Stephen Quirolgico, M Ramaswamy
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Macroscopic Dynamics in Large-Scale Data Networks

October 1, 2005
Author(s)
J Yuan, Kevin L. Mills
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Understanding Failure Response in Service Discovery Systems

March 1, 2005
Author(s)
Kevin L. Mills, Stephen Quirolgico, Christopher E. Dabrowski
Service discovery systems enable distributed components to find each other without prior arrangement, to express capabilities and needs, to aggregate into useful compositions, and to detect and adapt to changes. First-generation discovery systems can be

Modeling Reliability in Distributed Computer Networks

November 1, 2004
Author(s)
Christopher E. Dabrowski, Kevin L. Mills
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

A Cross-Correlation Based Method for Spatial-Temporal Traffic Analysis

March 10, 2004
Author(s)
Kevin L. Mills, J Yuan
Analyzing spatial-temporal characteristics of traffic in large-scale networks requires both suitable analysis method and a means to reduce the amount of data that must be collected. Of particular interest would be techniques that reduce the amount of data

Understanding Self-Healing in Service-Discovery Systems

November 1, 2003
Author(s)
Christopher E. Dabrowski, Kevin L. Mills
Service-discovery systems aim to provide consistent views of distributed components under varying network conditions. To achieve this aim, designers rely upon a variety of self-healing strategies, including: architecture and topology, failure-detection and

Performance of Service-Discovery Architectures in Response to Node Failures

June 1, 2003
Author(s)
Christopher E. Dabrowski, Kevin L. Mills, Andrew L. Rukhin
Current trends suggest future software systems will rely on service-discovery protocols to combine and recombine distributed services dynamically in reaction to changing conditions. We investigate the ability of selected designs for service-discovery

Adaptive Jitter Control for UPnP M-Search

May 1, 2003
Author(s)
Kevin L. Mills, Christopher E. Dabrowski
Selected service-discovery systems allow clients to issue multicast queries to locate network devices and services. Qualifying devices and services respond directly to clients; thus, in a large network, potential exists for responses to implode on a client

Self-Adaptive Leasing for Jini

March 1, 2003
Author(s)
K Bowers, Kevin L. Mills, Scott W. Rose
Distributed computing environments require strategies by which components can detect and recover from failures in remote, collaborating components. Many protocols for distributed systems employ a strategy based on leases, which grant a leaseholder with

Understanding the Correlation Structure of Network Traffic

December 24, 2002
Author(s)
Kevin L. Mills, J Yuan
This paper aims to improve current understanding of the correlation structure of traffic carried over large networks, such as the Internet. To achieve this aim we use simulation, adopting a methodology of homogenization to achieve a sufficiently large

Situated Computing: The Next Frontier for HCI Research

August 20, 2002
Author(s)
Kevin L. Mills, Jean C. Scholtz
Today, much of our information-intensive work is carried out at desktop computer workstations; however, increasingly people work and live on the move. Very soon, scads of small information processing appliances will be carried along from place to place as

Modeling CPU Demand in Heterogeneous Active Networks

June 1, 2002
Author(s)
V Galtier, Kevin L. Mills, Y Carlinet
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

Knowledge-Based Automation of a Design Method for Concurrent Systems

March 1, 2002
Author(s)
Kevin L. Mills, H Gomaa
This paper describes a knowledge-based approach to automate a software design method for concurrent and real-time systems. The approach uses multiple paradigms to represent knowledge embedded within the design method. Semantic data modeling provides the
