UPCOMING MEETING:-   

TITLE: VIRTUAL TALK:: “NAMED DATA NETWORKING IN CONNECTED AND SMART CITIES”

SPEAKER: Dr. Syed Hassan Ahmed

DATE and TIME: July 27th, 2020 – Starts at 4:00 p.m. EST/1:00 p.m. PST

LOCATION: Virtual hosted by Atlanta, GA/Austin, TX

ABSTRACT: 

Although, the current Internet architecture supports both static and mobility (Mobile IP) and tends to be secured, however, we still receive Spams every day and we also get significant delays in content retrieval, very often. Based on several literature findings, if we revisit the current Internet architecture, it was not originally designed to support mobility and was never prone to the hundreds of today’s sophisticated attacks on its reliability and privacy. Therefore, during the past decade, many research efforts have been triggered to redesign the current “host-centric” Internet architecture. The rationale behind those efforts is contingent on the Internet thirst of end-users, which has been exponentially growing to support fancy applications disseminating enormously sized contents. Almost, every effort to change the Internet architecture intersects at the concept of Content Delivery Networks. In this talk, the speaker will briefly look at the driving forces for one of the popular Future Internet architecture known as Named Data Network (NDN). Also, we will discuss our contributions to the field of Vehicular NDN. Finally, the speaker will look at NDN’s applicability and an application use-case in terms of automating traffic violation ticketing using vehicular communications.

Meeting link will be sent to the registrants.

BIOGRAPHY:

Dr. Syed Hassan Ahmed [S’13, M’17, SM’18] completed his BS from KUST, Pakistan, and his M.S./Ph.D. from Kyungpook National University, South Korea, both in computer science, in 2012 and 2017, respectively. Later, he was a post-doc with the University of Central Florida, Orlando, USA and on the faculty of the CS Department of Georgia Southern University (GSU) at Statesboro, USA, where his research interests included sensor and ad hoc networks, cyber-physical systems, vehicular communications, and Future Internet. Currently, Dr. Hassan is with JMA Wireless as a Product Specialist with a focus on distributed antenna systems and mmWave products.

 

MEETINGS from 2019:-

 

TITLE: TEAM ZYLINIUM DARPA SPECTRUM COLLABORATION CHALLENGE (SC2) RADIO DESIGN AND IMPLEMENTATION

SPEAKER: Dr. Bob Baxley —————————————————-DATE and TIME: November 21st, 2019  

ABSTRACT: 

This presentation describes the radio entry for Team Zylinium in the DARPA Spectrum Collaboration Challenge (SC2). SC2 is a competitive DARPA grand challenge where each team designs an autonomous software-defined radio (SDR) agent with the goal of efficiently operating in congested radio spectrum. Team Zylinium placed 3rd, 1st, and 3rd, respectively in the annual SC2 phases over three years winning a total of $2.25M. See https://www.spectrumcollaborationchallenge.com/ for more information.

SHORT BIOGRAPHY:

Dr. Bob Baxley is an entrepreneur focused on technologies at the intersection of machine learning and radio spectrum systems.  He is currently the CTO of Bastille where he helps build systems to sift through massive amounts of radio frequency data.

 

TITLE: “APPLICATIONS OF MODEL-BASED SYSTEMS ENGINEERING (MBSE) IN COMMUNICATIONS SYSTEMS DESIGN”

SPEAKER: Mr. Richard Wise ——————————————————————- October 1st, 2019

ABSTRACT: 

This presentation will discuss the status of a modeling effort that provides mission-relevant context to disconnected high-fidelity analysis tools for conducting a trade space analysis of an optimal communication systems architecture. Specifically, the architecture is a mobile ad-hoc network (MANET) established to provide broadband connectivity and aerial surveillance in a natural disaster response scenario. A model-based systems engineering (MBSE) approach leveraging SysML is employed to manage the complexity of not only the definition of the MANET architecture and its relationship to stakeholder priorities, but also the interface to the analysis tools and the orchestration of the trade space analysis itself. Realization of modeling objectives such as reusability and scalability have resulted in libraries of common block definitions and patterns that function as an interface between a value-oriented decision model providing mission-relevant context, the architectural definition of the MANET, and analysis tools performing the complex calculations. Initial work has leveraged the commercial tool, Cameo Systems Modeler and the companion Cameo Simulation Toolkit to demonstrate the exchange of specific MANET architecture configurations in an operational scenario with open-source network analysis tools via text-based files and ingesting the resulting network performance values back into the model.

SHORT BIOGRAPHY:

Mr. Wise joined GTRI as a Research Engineer in 2012 with a Master’s Degree in Applied Systems Engineering from the Georgia Institute of Technology and a Bachelor of Science in Aerospace Engineering from Embry-Riddle Aeronautical University.
