FAU Works on New Subsea Wireless Communications Technology

first_imgResearchers from Florida Atlantic University’s College of Engineering and Computer Science have received a $500,000 grant from the National Science Foundation to design, deploy and evaluate a first-of-its-kind software-defined testbed for real-time undersea wireless communications (data, voice, and video streaming) and surveillance. The four-year project titled, “Cognitive Networking of the Oceans: Localization and Tracking Fundamentals,” provides the foundations for a four-tier heterogeneous network architecture involving autonomous undersea vehicles (AUVs), autonomous water-surface vehicles (ASVs), unmanned aerial vehicles (UAVs), and satellites.“Today, cognitive undersea acoustics is a key wireless communication technology that can be used for a wide range of military, commercial, and scientific applications, including tactical surveillance, offshore exploration, monitoring of subsea machinery such as oil-rigs and pipelines, disaster prevention as well as the study of marine life,” said Stella N. Batalama, Ph.D., principal investigator and dean of FAU’s College of Engineering and Computer Science, who is collaborating with Dimitris Pados, Ph.D., co-principal investigator, professor in FAU’s Department of Computer and Electrical Engineering and Computer Science and I-SENSE Fellow. “With this National Science Foundation grant, our goal is to significantly advance the state-of-the-art in 3D passive undersea acoustic localization by providing novel algorithmic solutions to address the challenges that exist in wireless networked communication, navigation and surveillance.”This technology developed at FAU should reportedly advance software-defined undersea acoustic technology for cognitive networking and will help to address and resolve interoperability issues in heterogeneous network deployments that include real-time interaction between undersea, water-surface, aerial, and satellite communication nodes. Batalama and Pados will work to design and develop novel in-house software-defined modules of the undersea network to maximize flexibility and minimize form-factor and cost.“Undersea wireless communications and networking has a wide range of applications, but is still a daunting task due to the very nature of the water propagation medium,” said Pados. “Long propagation delays, Doppler effects due to vehicle and water movement, and the highly dynamic multipath nature of the undersea environment result in significant errors and outliers in received data measurements. There is a great need for modular software and hardware architectures that enable rapid deployment and evaluation of new robust protocol designs.”The researchers will develop novel optimal algorithms for oceanic-scale 3D acoustic underwater localization and tracking and will develop software and hardware technology to create and maintain a programmable software-defined undersea acoustic testbed comprising of four nodes. The project will begin with algorithmic designs and continue to the development, deployment and evaluation of a software-defined interoperable cross-medium cross-layer network testbed in which undersea AUVs, aerial UAVs, water-surface ASVs, and satellite nodes will form a single cognitively optimized super network.Batalama and Pados will evaluate and test the performance of their technique (range, accuracy, and data throughput) first in a 30-foot-deep acoustic test tank at FAU, and then in the Atlantic Ocean off the coast of Dania Beach at FAU’s Institute for Ocean and Systems Engineering (SeaTech). Localization capabilities will be demonstrated in communication, command and control application scenarios for remote wireless navigation and surveillance.“This research spearheaded by professor Batalama and professor Pados explores for the first time both theoretical and deployment challenges that arise during the integration of autonomous and aerial-assisted mobile undersea communication systems at the oceanic scale,” said Daniel C. Flynn, Ph.D., FAU’s vice president for research. “Their project will decisively contribute to the emerging area of undersea acoustic networking, which has an abundance of socially relevant applications such as search and rescue, pollution monitoring and oceanographic data collection.”The FAU project will integrate research and education at the graduate and undergraduate levels at the University as well outreach to middle and high school students. FAU also will pursue opportunities for technology transfer in this field.Source: FAUlast_img read more

(AP Photo/Keith Srakocic)HUNTINGTON, W.Va. (AP) – Marshall and Pittsburgh have agreed to a home-and-home football series in 2016 and 2020.Marshall athletic director Mike Hamrick said Tuesday the Thundering Herd will visit Heinz Field in Pittsburgh on Oct. 1, 2016. The Panthers will play in Huntington on Sept. 26, 2020.It will mark the first meetings between the schools.Hamrick says his goal has been to bring quality, nationally recognized programs on a home-and-home basis to Huntington, and “the addition of Pitt is another step in that process.”Marshall also has home-and-home arrangements with two other Atlantic Coast Conference teams, Louisville and North Carolina State.last_img read more

Washington Mudslide Victims to Get Help from Papa John’s Local Franchises

first_imgFacebook216Tweet0Pin0 Submitted by Papa John’sPapa John’s Pizza announced recently that profits from all sales on Thursday, April 3th will be donated to the families of the Oso, Washington Mudslide victims.”Being locally owned and operated we knew we needed to reach out and help our community. We own a store in Marysville which is very close to Oso so we are currently donating pizzas daily to the families as well as the search & rescue personnel,” said Diane Kaelin, a local Papa John’s Franchisee.Al Randazzo, Papa Johns Franchise Business Director for the Western US says, “The loss these families are experiencing is devastating. Our gratitude, respect and admiration to all of the rescue workers and to the help the Salvation Army is providing.  We are happy to be able to provide this kind of support with our sincerest sympathies to all the families.”All 40 Western Washington locations will partner with three Spokane and three Tri Cities locations to donate profits made from the entire day’s sales to the Salvation Army’s Disaster Relief Fund. The regular menu will be available in addition, they will offer a large one topping pizza for $10 dollars on Thursday April 3rd. Offers will be available online for 24 hours only at www.papa johns.com and with carryout at each location.This is a second time these Papa John’s Franchises banned together to support their community in a time of tragedy. In December 2009 they raised $141,000 for the four fallen Lakewood Washington Police Officers.last_img read more

Mallard’s Team of the Week — Team Wined it Up

first_imgNot bad says the folks at Mallard’s Source for sports which selected the squad Team of the Week.The West Kootenay Glacier Challenge MS Bike tour had cyclists trek from New Denver to Nelson one day and Nelson to New Denver the next to help find a cure while getting a whole of exercise and scenery looking.Multiple sclerosis (MS) is an inflammatory disease in which the insulating covers of nerve cells in the brain and spinal cord and damaged.The Nelson Daily Ad Manager John McCuaig (pictured far left) also wanted to add some appreciation with a dinner voucher for Team Wined it Up.Pictured from left, The Nelson Daily’s McCuaig, Jennifer Ellis, David Johnson, Sandy Mitchell (Captain), Jay Puder and Jay Ratzlaff. The event raised more than $80,000.One team, Team Cranked Up, brought in more than $9,000.Not to be outdone was Team Wined it Up which came a close second at more than $7,500 raised for MS Research.last_img read more
