Optimizing Authentication in Media Independent Handovers using IEEE 802.21

August 6, 2009
Author(s)
Antonio Izquierdo Manzanares, Nada T. Golmie, Richard A. Rouil
In this paper we study the performance of the authentication process in media independent handovers, and consider the impact of using IEEE 802.21 link triggers to achieve seamless mobility. We describe all interactions between the 802.21 services and the

Performance Metrics for IEEE 802.21 Media Independent Handover (MIH) Signaling

March 2, 2009
Author(s)
David W. Griffith, Richard A. Rouil, Nada T. Golmie
The IEEE 802.21 Media Independent Handover (MIH) working group is developing a set of mechanisms to facilitate migration of mobile users between access networks that use different link-layer technologies. Among these are mobility managers that create and

Adaptive Channel Scanning for IEEE 802.16e

October 23, 2006
Author(s)
Richard A. Rouil, Nada T. Golmie
In this article we propose an adaptive algorithm that determines the duration and frequency of channel scanning in order to facilitate the discovery of neighboring base stations and handovers across multiple IEEE 802.16 networks. The proposed algorithm

Unsupervised Anomaly Detection System Using Next-Generation Router Architecture

October 1, 2006
Author(s)
Richard A. Rouil, Nicolas Chevrollier, Nada T. Golmie
Unlike many intrusion detection systems that rely mostly on labeled training data, we propose a novel technique for anomaly detection based on unsupervised learning and we apply it to counter denial-of-service attacks. Initial simulation results suggest

Comments on IEEE 802.21, IEEE 802.21-05-0289, San Francisco, CA

July 1, 2005
Author(s)
Nicolas Montavont, Richard A. Rouil, Nada T. Golmie
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometric systems on a population approaching 1,000 individuals. Majority of prior studies of multimodal
