Article
Full-text available
Purpose This article examines aspects of information communication technology (ICT) connectivity among the understudied population of low-income older adults living in rural and peri-urban subsidized housing. We aim to investigate if variations exist in access and connectivity when economic and housing conditions are constant and use data from nort...
Conference Paper
The Science DMZ is a network research tool offering superior large science data transmission between two locations. Through a network design that places the Science DMZ at the edge of the campus network, the Science DMZ defines a network path that avoids packet-inspecting devices (firewalls, packet shapers) and produces near line-rate transmission...

Datacasting employs the excess bandwidth from digital television signals for use in one-way data transmission, and it is being used successfully for high-speed downloads at fixed locations. There is considerable interest in extending datacast usage to mobile users, although there are reception challenges in the mobile environment that can significa...
Conference Paper
Full-text available
Datacasting involves the use of the excess bandwidth in a digital terrestrial television station's stream to deliver broadcasted data to a variety of receivers. Initially developed as a stationary fixed technology, this project involves receiving this broadcast in a mobile environment. This one-way transmission allows the datacast receiver to decou...
Article
Full-text available
Information enabled by technology is used to support good decision-making in the public safety arena. In the information age, the current implementation includes the installation of laptop computers and other mobile computing technology into mobile environments including ambulances, fire vehicles and police cruisers. Typically, these computing devi...
Conference Paper
Digital Subscriber Line (DSL) technology deployments have steadily increased in the last several years with current deployment counts topping over 200 million lines. While Asymmetric DSL (ADSL) technology continues to see the predominate share of access lines, Very high speed DSL (VDSL) has been in development for several years and has yet to overt...

Conference Paper
The work described here relates to an effort to assess the reliability and robustness of datacasting for use in the mobile environment. Datacasting employs the excess bandwidth from digital television signals for use in one-way data transmission and it is being used successfully for high-speed downloads at fixed receiver locations. It is being cons...
Conference Paper
Full-text available
Public safety officers need current, accurate and complete information to maintain the security of their communities. Existing communications systems for public safety officers consist of analog and digital radios, supplemented with cell phone communications. Dispatchers with a need to broadcast information can only do so via voice. Small data pack...
Article
Full-text available
This paper outlines the problems in currently available authentication methods, such as EAP-TTLS, EAP-PEAP and EAP-FAST, and describes the desirable properties of a standard outer method. We examine the interaction between inner and outer methods and the types of issues that presently exist. We propose a new authentication method, EAP-PSK [PSK] wit...
Conference Paper
Full-text available
Datacasting is a new service offering available as a result of the deployment of digital television (DTV). Several services are available to users of datacasting in the educational, business and public safety arena. Using the ATSC A/90 Standard Model, datacasting has the ability to reach the public in areas traditionally not support by existing hig...

Article
Full-text available
The issue of radio frequency interference in Digital Subscriber Line (DSL) networks is of particular concern in urban areas with many strong radio sources nearby. This paper investigates in detail the mechanisms underlying the capacity reduction due to the presence of radio frequency signals from Amplitude Modulated (AM) broadcast stations in an AD...
Article
Full-text available
One of the most commonly deployed DSL variants is ADSL. Despite this fact, deployment of new robust and reliable ADSL services is increasingly difficult due, in part, to the physical limitations of the copper telephone system infrastructure, and also in part to the lack of useful ADSL network debugging tools. ADSL service providers and technicians...
Conference Paper
To support cooperation, communication between AUVs must move beyond passing streams of data. Cooperating AUVs must also be able to exchange information and request help from their collaborators. This communication must be effective despite low-bandwidth communication channels, high error rates, and limited computational effort available for process...
