Enhanced Schemes for L2 Handover in IEEE 802.11 Networks and their Evaluations

September 1, 2005
Author(s)
Nicolas Montavont, Nicolas Montavont, T Noel
Given the relatively limited coverage area of 802.11 access points, stations moving inside WLAN are often required to perform a handover. The time needed for a STA to switch from one AP to another is too long for real-time applications to continue

Overview of the TREC 2004 Novelty Track

August 1, 2005
Author(s)
Ian M. Soboroff
TREC 2004 marks the third and final year for the Novelty Track. The task is as follows: Given a TREC topic and an ordered list of documents, systems must find relevant and novel sentences that should be returned to the user from this set. This task

Overview of the TREC 2004 Question Answering Track

Author(s)
Ellen M. Voorhees
The TREC 2004 Question Answering track contained a single task in which question series were used to define a set of targets. Each series contained factoid and list questions and related to a single target. The final question in the series was an Other

Overview of the TREC 2004 Robust Retrieval Track

Kotikalapudi Sriram
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

Application of Beamforming in Wireless Location Estimation

July 1, 2005
Author(s)
Kamran Sayrafian
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

Securing Voice Over IP Networks

May 27, 2005
Author(s)
T J. Walsh, D. Richard Kuhn
Voice over IP - the transmission of voice over traditional packet-switched IP networks - is one of the hottest trends in telecommunications. As with any new technology, VOIP introduces both opportunities and problems. Lower cost and greater flexibility are
