News/2010-06-11 Improved WiMAX module, IMT-Advanced support, openWNS USB sticks

Another major update of the RWTH Aachen University Open Source Wireless Network Simulator (openWNS) was uploaded to Launchpad. As promised, the IEEE 802.16 WiMAX module "WiMAC" was further enhanced and can now be used in IMT-Advanced compliant evaluation scenarios. Additionally openWNS is now also available on bootable USB sticks.

WiMAX module:

The IEEE 802.16 WiMAX simulator module "WiMAC" is now also capable to support OFDMA. Currently a configuration with scalable bandwidth between 5 MHz and 20 MHz, 1/8 cyclic prefix and Time Division Duplex (TDD) is available. A first test configuration for beamforming and Space Division Multiple Access (SDMA) has also been published.

IMT-Advanced Evaluation:

IMT-Advanced Evaluation Methodology compliant scenarios for Urban Macro, Urban Micro, Rural Macro, Suburban Macro and Indoor Hotspot deployment scenarios have been published to evaluate WiMAX system performance. The scenario setup includes the node deployment, large-scale fading channel model, antenna characteristics and transceiver properties.

openWNS on USB:

We were able to create a fully functional openWNS installation on a bootable USB stick. Go to http://www.openwns.org/Wiki/Download to download a copy. The minimum requirement is an empty USB stick with at least 8GB capacity. Everything needed to get to know the simulator by completing the openWNS tutorial is already set up.

News/2009-06-16 openWNS was presented at European Wireless 2009

Last month the Eurpean Wireless 2009 took place in Aalborg. There we had the opportunity to present openWNS to the research community. The paper I presented gives an overview of all the features currently available. I have attached it to this post. The feedback was encouraging and people showed interest to try it out. We distributed LiveDVDs to let listeners quickly check out the tool. Aalborg itself was fun. We arrived there just before the childrens carnival celebration started but unfortunately had to leave just before the main festivities began.

So check out the paper here. I think it gives a good overview of the simulation platform and simulation models and helps to get started with the simulator.

News/2009-03-17 openWNS source code statistics now on ohloh.net

Ohloh.net is a great site that monitors open source projects to extract information on the activity of open source projects. It does so by reading the source code repositories and mangling that data to derive statistics on contributors, used programming languages, source code to comment ratios, etc.

Since mid of February the guys at ohloh.net finally support the bazaar version control system and as of today openWNS source code is monitored on ohloh.net. See the statistics for yourself here:

News/2009-02-24 openWNS Wrowser released!

I just released the open Wireless network simulator results browser. A nice graphical frontend for managing your simulation campaigns with openWNS. The Wrowser offers support to create and queue your simulations to a simulation cluster. Simulation results are automatically stored to a database backend and results from multiple simulation runs can be conveniently combined using the GUI.

Wrowser also has support to preview your simulator configuration to help you to check your scenarios for consistency, before running a large campaign. You can view some screenshots here.

This release of Wrowser should be considered beta. It worked internally in our department very well in the past. This does not mean that it does work for you out of the box. We decided to let Wrowser get into the wild now and we'll be glad to further improve the tools, but we need your feedback.

Regards,

• Daniel

News/2009-01-26 802.11 s/n Protocol Stack Published

Several new modules forming a 802.11 s/n compatible protocol stack simulator have been published on Launchpad. Those include an OFDMA Phy layer, an IP layer, and a 802.11 WLAN data link layer. The 802.11 simulator supports Mesh networks as defined by Tasg Group (TG) s and new features introduces by TGn. The openWNS Users Manual (available at the Documentation page) covers the WiFi Module extensively.

New extended traffic models including Markov Modulated Poisson Process (MMPP) have also been published and are part of the openWNS Module Constanze, see Constanzes Launchpad page.
