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 More...

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
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://

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
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
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 The project homepage is located at 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 (
New INET Framework web site

We have set up a dedicated web site for the INET Framework at 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!

About OMNeT++ Workshop 2009
Thursday, 12 March 2009 08:32
The 2nd International Workshop on OMNeT++ took place last week in Rome, Italy. It was a great success: 18 papers and posters were presented (selected from nearly twice as many submissions!), and we again filled the room for the most part of the day, with about 40 people being present. With the INET@github discussion and the hands-on tutorial on the upcoming MiXiM model framework, the program ended after 7pm, and then we went out for an informal dinner in a nice nearby restaurant. You'll find the programme on the workshop site, together with the slides of the presentations:
