4 SBIR Wins for SNT: 2 Phase Is and 2 Phase IIs

SNT has been awarded 4 Small Business Innovation Research (SBIR) Grants.

The first one, Bio-Inspired Approaches to Secure Scalable Networking, is a Phase I grant from the US Army.

The second, Cross-Layer Architectures, Semantics and Strategies (CLASS), is also a Phase I grant from the US Army.

The third, Seamless Route Management & Route Distribution Across Heterogeneous Networks, is an Army Phase II Project.

The fourth is a Navy Phase II SBIR called Scalable Real-Time Analysis Environment for Wireless Networks. 

Two New Research Papers Featuring Network Emulation with QualNet

SNT engineers have published two papers featuring groundbreaking research with QualNet. Both deal with QualNet's True Emulation technology.

The first one, Network Design and Implementation Using Emulation-based Analysis was part of the MILCOM 2007 program.

Abstract

Current network design and implementation processes employ simulation for analysis at the network design phase and directly step into prototyping based on this analysis followed by physical testbed analysis and full scale deployment. Due to abstractions in the simulated models of the network protocols, it is difficult to maintain accurate predictability of the network performance as the process moves into the detailed design and the subsequent prototyping phase. This paper presents an emulation-based approach for network design and implementation and aims to bridge the gap between simulation and the prototyping phase. Emulation-based analysis uses emulations of protocols and applications in real-time, together with high fidelity simulation models of physical hardware, environment effects and mobility.

This paper provides an overview of the approach and presents a case study to highlight its ability to allow for accurate predictability of network performance as the network matures from design to deployment.

The second, Wireless Network Testing and Evaluation using Real-time Emulation, was published in the June/July 2007 Issue of ITEA Journal of Test and Evaluation.

Abstract

Full scale physical testbeds used in network testing and evaluation of wireless network systems have certain limitations that do not allow testers and evaluators to obtain results in an easy way. Considerable time, effort and resource costs have to be invested to obtain comprehensive performance results on such testbeds.

This paper proposes an alternative approach to network testing and evaluation based on the real–time emulation capability of the QualNet simulator. It provides an overview of the approach and provides illustrations to outline how a testbed based on real-time emulation can be set up. The effectiveness of such a testbed is highlighted by a use case, where performance evaluation results are presented for a wireless ad hoc network which is to be deployed over a range of scenarios.

SNT to Showcase QualNet at the WiMAX Forum Member Conference January 30th in Kona, Hawaii

SNT will attend the January WiMAX Forum Member Conference in Hawaii at the Hilton Waikoloa Village January 28th - February 1st. On Wednesday, Jan 30th, SNT will showcase QualNet in the Showcase Exhibit Space near the seminar area.

Come see how QualNet can improve the design of your WiMAX equipment and networks as we demonstrate the scalability and fidelity of QualNet WiMAX simulation models. We will show a WiMAX Forum AATG specified scenario with 19 cells and a WiMAX simulation network carrying live applications (streaming video, VoIP) using the IPNE interface.

SNT is a member of WiMAX Forum. For more details see: http://www.wimaxforum.org.
