Welcome to the OMNeT++ Community!

OMNeT++ is an extensible, modular, component-based C++ simulation library and framework, primarily for building network simulators. "Network" is meant in a broader sense that includes wired and wireless communication networks, on-chip networks, queueing networks, and so on. Domain-specific functionality such as support for sensor networks, wireless ad-hoc networks, Internet protocols, performance modeling, photonic networks, etc., is provided by model frameworks, developed as independent projects. OMNeT++ offers an Eclipse-based IDE, a graphical runtime environment, and a host of other tools. There are extensions for real-time simulation, network emulation, alternative programming languages (Java, C#), database integration, SystemC integration, and several other functions.

OMNeT++ is free for academic and non-profit use, and it is a widely used platform in the global scientific community. Commercial users must obtain a license from omnest.com. More...

Announcement: oTWLAN – a tool to simulate tactical ad-hoc networks
Friday, 17 July 2009 12:51

oTWLAN models a wireless ad-hoc network, which supports multi-level precedence and preemption (MLPP) over a DSSS radio. This open source project facilitates throughput/delay performance study through a GUI based user interface. oTWLAN has many similar characteristics to WLAN (IEEE 802.11) but also provides a 100kbps radio channel for enlarged radio coverage, relaying of traffic for increased service coverage area and priority handling of user traffic. The latter is especially important for military and emergency network. The simulator has been developed within the GOSIKT project at the Norwegian Defence Research Establishment where we study the performance of PKI over tactical ad-hoc networks. Chapter 2 in the user manual included in this open source project illustrates the usage of the simulator while other chapters describe the network protocols implemented.

Later versions of this project will be published on http://sourceforge.net/projects/otwlan/

 
Announcement: Energy Framework 0.9
Friday, 17 July 2009 08:24
The Communication Networks and Systems Lab at SICS is happy to announce version 0.9 of the Energy Framework.

The Energy Framework is a collection of modules that allows flexible and extensible modeling of battery consumption of wireless devices. It currently uses OMNET++-3 and mobility-fw2.0p3,but is intended to be relatively framework independent.  Code is available at http://www.sics.se/nets/software.

SZTAKI Grid Portal for Simulations
Tuesday, 14 July 2009 09:36
The GASuC team at the Laboratory of Parallel and Distributed System (LPDS), MTA SZTAKI has announced public access to a computing grid for OMNeT++ simulations. The grid can be accessed via a Web portal, and currently lets users submit and run pure INET Framework and Queueinglib simulations on a 10-CPU grid architecture. (Further grid nodes will be added as needed.)

The LPDS team is inviting you to try and run simulations on the grid!  Feedback is welcome.

Announcement: MiXiM 1.0 released
Tuesday, 23 June 2009 20:46
The MiXiM team is happy to announce the first official MiXiM release, MiXiM 1.0. MiXiM is an attempt to merge several OMNeT++ simulators written to support mobile and wireless simulations. This release contains only the parts of MiXiM which we considered tested and stable enough for release. These are:
  • a base model for a detailed wireless physical layer
  • analogue model implementations for "Jakes fading", "Lognormal shadowing" as well as a simple path loss model
  • a CSMA Mac layer and a 802.11 Mac layer
  • mobility pattern modules known from the Mobility Framework (like Tractor-, Turtle- and CircleMobility)
MiXiM can be downloaded from the project's Sourceforge download area, or can be checked out directly from the git repository at git://mixim.git.sourceforge.net/gitroot/mixim.

Still in development are implementations of a S- and T-Mac protocols. You can find the parts which are still in development in the git repository's "development" branch. Also, Jérôme Rousselot has written a MiXiM branch which contains a detailed model of an UWB physical layer; it can be found on github as the mixim-uwb project.

xMIPv6 Simulation Model Available for OMNeT++ 4.0
Saturday, 06 June 2009 09:05
Thanks to the efforts of Andras Varga and Rudolf Hornig, the Extensible Mobile IPv6 (xMIPv6) model is now available for OMNeT++4.0 and can be downloaded from http://github.com/zarrar/xMIPv6/tree/master.
 
Comments and feedback will be appreciated.
 
Welcome to the new OMNeT++ Community Website
Friday, 22 May 2009 13:51
Dear OMNeT++ Users,

Welcome to the new, redesigned OMNeT++ community site. The old, Geeklog-based website infrastructure has served us in the last 6 years, but its age has started to show, and had to be replaced. The new website is based on Joomla, and we hope it will solve all our previous problems. A few things you should now:

  • We have removed all the unused services. Calendars, polls, Web links are gone.
  • The forum was also dropped, as it was mostly a write-only medium, and the new mailing list will double as a forum too.
  • The content of the site is mostly the same (we converted almost all content), but we have reorganized the site navigation a bit.
  • A bibtex-based Publication Database was added for keeping track of OMNeT++ related papers. We made a good effort to collect publications from several online libraries and collections, but we don't know about the coverage. Please help us getting up-to-date by checking that it contains all your publications! You can submit the missing ones via a web form.
  • A Model Catalog was added to gather all OMNeT++ models in a single place.
  • User accounts were not taken over from the old site. Please re-register on the new site if you wish.
  • We moved the mailing list to Google Groups. This allows you to follow the discussion via XML feeds, write to the group from the web directly, browse and search the archive in threaded mode. We have moved the old member list, however if you have recently subscribed to the omnetpp list, you may have to re-subscribe. The mailing list's address has changed, but the old list address still forwards to the new e-mail address. We are sorry for any inconvenience.
  • As a registered user, you will be able to submit news items, new models and publications.
 
Castalia 2.0 released
Friday, 15 May 2009 12:08
Castalia 2.0 (for OMNeT++ 3.x) has been released. Castalia is a simulator for Wireless Sensor Networks (WSN), Body Area Networks (BAN), and generally networks of low-power embedded devices. It offers an advanced channel model based on empirical measurements that supports mobility and temporal variability. It also offers many features that are often neglected in network-level simulation, such as realistic radio modeling and access, node clock drift, and physical process modeling. Castalia is an expandable, modular and user-friendly simulator with a growing research community. For more info go to http://castalia.npc.nicta.com.au.
 
Mobility Framework for Omnet++ 4.0 beta 2
Monday, 06 April 2009 12:45
The second release of the Mobility Framework for Omnet++ 4 is now available at http://github.com/mobility-fw/mf-opp4/downloads. The project homepage is located at http://wiki.github.com/mobility-fw/mf-opp4. It is now much easier to use, and includes some new simulation models. Please try the networks/ieee802154 example network to get started.

This framework is made available so that MF2 users can benefit from Omnet++ 4 new features, and to provide access to additional modules (detailed multiple access interference model, IEEE 802.15.4 CSMA, radio power consumption model for TI CC 1100 and TI CC 2420). In the future, the additional modules provided in this framework might be ported to the MiXiM simulation framework (http://mixim.sourceforge.net).
 
New INET Framework web site
Thursday, 12 March 2009 09:01
We have set up a dedicated web site for the INET Framework at http://inet.omnetpp.org. The design and content are very basic at the moment -- we'll appreciate your help in refining and expanding it.
 
OMNeT++ 4.0 released
Thursday, 12 March 2009 08:44
After more than 3 years of intense work of the team, 8 beta releases and two release candidates, OMNeT++ 4.0 has been finally released. (We'd like to take the opportunity to congratulate ourselves for this great achievement! :) With the new Eclipse-based IDE, greatly enhanced NED language and simulation kernel, and tons of other improvements, 4.0 is guaranteed to redefine the way you do simulations with OMNeT++, and it will open up new horizons.

Downloads are available in the download area. Report bugs in our bugtracker.

Read on for a brief summary of what's new in 4.0!
