Colloquium Speaker: George F. Riley
George F. Riley is an Associate Professor of Electrical and Computer Engineering at the Georgia Institute of Technology. He received his Ph.D. in computer science from the Georgia Institute of Technology, College of Computing, in August 2001. His research interests are large--scale simulation using distributed simulation methods. He is the developer of Parallel/Distributed ns2 (pdns), the Georgia Tech Network Simulator (GTNetS), and is co-PI on the ns3 development effort. Before turning to a career in academia, Dr. Riley spent 20 years as an independent consultant and business owner, primarily working at the Air Force Eastern Test Range, developing and deploying systems for real-time missile launch support. He can be reached via email at firstname.lastname@example.org.
The ns-3 network simulation environment is the result of a multi-year effort funded by the U.S. National Science Foundation, and is designed to replace the aging but popular ns-2 simulator. In this talk, we will start by discussing some of the basic concepts used when creating simulations of computer networks, and the types of questions that can be analyzed by network simulation tools. Then we will discuss some of the basic design of ns-3 and the tradeoffs that went into those design decisions. Finally, we will demonstrate a simple ns-3 simulation and show the results.
