Scientific Research Corporation Develops Hardware-in-the-Loop Warfare Simulation With QualNet.

LOS ANGELES--(BUSINESS WIRE)--July 23, 2002--Scalable Network Technologies (SNT), the makers of QualNet software, announced today that Scientific Research Corporation (SRC) is a customer. Headquartered in Atlanta, SRC provides innovative products and services to government and private industry in the area of electronic engineering. SRC chose QualNet to model wireless communications in a number of efforts, including a warfighting simulation involving computers and real-life aircraft in training exercises.

"QualNet's excellent support for wireless network modeling and outstanding speed were the reasons why we purchased their network simulator," said Dr. Andreas Yankopolus, Senior Engineer in SRC's Wireless Networking Division. "One of our projects involves integrating QualNet into a simulation that will involve four real and up to 64 virtual hardware-in-the-loop entities. Another involves building a QualNet simulation with 100 simulated sensors and multiple warfighters and adversaries. Hardware-in-the-loop entities, such as flight simulators and real remotely piloted vehicles conducting training exercises, add more realism to the simulation.

"Hardware-in-the-loop simulation is getting a lot of interest right now, as a simulation by itself doesn't impress anyone," expanded Yankopolus. "A real-time communication simulator like QualNet is a very powerful technology for getting the most out of your simulation dollars, since it allows you to combine real and simulated entities, giving the realism of actual hardware with the inexpensive scalability of simulated entities. QualNet was about 100 times faster than our previous simulator, thereby allowing hardware-in-the-loop simulations, which is what brings the extra value. The speed of simulation realized with QualNet also allows us to get results quickly and explore the parameter space more thoroughly. This means we get a bigger, more accurate picture of the network.

"Besides speed and real-time integration to warfighting simulators, IP networking is one of QualNet's strong points," continued Yankopolus. "We're using QualNet to conduct scalability tests on a mobile ad hoc networking protocol we wrote from scratch. In most simulation projects, at least 75 percent of our time is spent coding and debugging networking protocols. Since we were new to QualNet, we had a learning curve to overcome, but after two weeks, our experienced coders were already productive with QualNet," continued Yankopolus. "Switching to QualNet is not hard because the simulator is intuitive and its source code is well documented. Tech support has also been very helpful and quick to respond to our questions."

Los Angeles-based Scalable Network Technologies also highlights the parallel execution capabilities of the network simulator. "QualNet simulates networks to a high degree of detail at a fast speed," stated SNT's Founder and CEO, Rajive Bagrodia. "But above and beyond its speed on a single processor, parallel QualNet lets users simulate much larger models in real-time." In parallel QualNet, the simulator distributes the computing load across multiple processors, processing more events in the same amount of time. "Because QualNet produces accurate answers fast, it is poised to achieve widespread acceptance in network planning, deployment, and management applications," said Bagrodia.
