We are happy to announce that Scenargie® 1.4, the newest version of our simulator, has been released. Scenargie® 1.4 includes many new models including an ad-hoc routing protocol and two RF propagation models in Base Simulator, and a full protocol stack of Wireless Access in Vehicular Environments (WAVE), including multi-channel operations defined in IEEE 1609.4 in ITS Extension Module. Further, Visual Lab (Scenargie's GUI) has been extended significantly for improved usability. These new models and features allow customers to simulate a WAVE based ITS more flexibly and effectively than ever. We have also officially supported 64-bit Linux operating systems in Scenargie® 1.4.

A detailed list of added features and models is as follows:

■Base Simulator
  - Trace-based propagation model
  - Indoor propagation model (COST231 Indoor)
  - Ad-hoc routing protocol (AODV, OLSR)
  - Flat fading model that accounts for time correlation and dynamic velocity

■Visual Lab
  - Path loss calculation between nodes in RF Propagation Analyzer
  - Display of ray paths between nodes
  - GIS data creation for indoor environments
  - Display of object properties in a spreadsheet style
  - Improved Object Type Editor

■ITS Extension Module
 - Multi-channel operations defined in IEEE 1609.4
 - WSMP*-IPv6 dual system stack defined in IEEE 1609.3
  *WSMP: WAVE Short Message Protocol

■Dot Eleven Module
 - Adaptive rate control model (ARF*)
  *ARF: Auto Rate Fallback

We are happyt to announce the release of Scenargie® 1.3. We enhanced Visual Lab in its visual effect and usability. Also, we newly added "ITS Extension Module" and " High Fidelity Propagation Module to our product lineup to achieve ITS simulation and to enable fine radio propagation analysis by ray tracing.

October 26 - 28, 2009

We presented "Scenargie^®" at BROADBAND TAIWAN 2009 in Taipei (Taiwan) on October 26-28. It was a great opportunity for us to demonstrate seamless interaction between real multi-media application and simulated network through emulation, and we found out that many carriers and vendors were highly interested in it.
