Indoor Localization: Technology That Can Save First Responder Lives

December 1, 2007
Author(s)
Nader Moayeri, Camillo A. Gentile, Kamran Sayrafian, Michael R. Souryal
Every year a number of first responders lose their lives while battling fires or rescuing civilians during such emergencies. Indoor localization or location tracking roughly provides the same capability inside buildings that GPS does outdoors. It allows a

Sensor Location through Linear Programming with Arrival Angle Constraints

March 14, 2007
Author(s)
Camillo Gentile, J Shiu
In previous work, we established a linear programming framework to determine sensor location from measured link distances between neighboring nodes in a network. Besides providing greater accuracy compared to other techniques, linear programs in particular

A Comprehensive Evaluation of Indoor ranging using Ultra-Wideband Technology

January 15, 2007
Author(s)
Camillo Gentile, El Kik
Ultra-wideband technology shows promise for precision ranging due to its fine time resolution to resolve multipath fading and the presence of lower frequencies in the baseband to penetrate walls. While a concerted effort has been conducted in the extensive

An Evaluation of Ultra Wideband Technology for Indoor Ranging

Camillo Gentile, El Kik
Ultra wideband technology shows promise for precision ranging due to its fine time resolution to resolve multipath fading and the presence of lower frequencies in the baseband to penetrate walls. While a concerted effort has been conducted in the

Evaluation of Indoor Localization Techniques

July 1, 2005
Author(s)
Camillo Gentile, Kamran Sayrafian, Nader Moayeri
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

General Purpose Calculator for Outdoor Propagation Loss

Author(s)
Leonard E. Miller, Camillo Gentile, D Kaspar
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

Segmentation for Robust Tracking in the Presence of Severe Occlusion

February 18, 2004
Author(s)
Camillo A. Gentile, M Sznaier, O Camps
Tracking an object in a sequence of images can fail due to partial occlusion or clutter. Robustness to occlusion can be increased by tracking the object as a set of parts such that not all of these are occluded at the same time. However, successful

Expected Multi-Hop Power Consumption in Mobile Ad-Hoc Networks

March 1, 2003
Author(s)
Camillo A. Gentile
Mobile Ad-Hoc Networks provide the means to reduce significantly the power required for routing from source to destination through multi-hops between other nodes in the network. In the presence of mobility, only continuous updating can guarantee routes

Kinetic Minimum-Power Routing and Clustering in Mobile Ad-Hoc Networks

September 1, 2002
Author(s)
Camillo Gentile, R E. Van Dyck, J Haerri
We have previously developed a distributed routing algorithm which minimizes the number of overhead messages necessary to maintain the minimum-power multi-hop routes in a mobile ad-hoc network, assuming a piece-wise linear model for the motion of the nodes

Kinetic Spanning Trees for Minimum-Power Routing in MANETS

May 30, 2002
Author(s)
Camillo Gentile, R E. Van Dyck
A distributed kinetic spanning tree algorithm is proposed for routing in wireless mobile ad hoc networks. Assuming a piecewise linear motion model for the nodes, the sequence of shortest-path spanning trees is determined, valid until the time of the next

Segmentation for Robust Tracking in the Presence of Severe Occlusion

December 3, 2001
Author(s)
Camillo A. Gentile, M Sznaier, O Camps
Tracking an object in a sequence of images can fail due to partial occlusion or clutter. Robustness can be increased by tracking a set of parts, provided that a suitable set can be identified. In this paper we propose a novel segmentation, specifically
