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...

OppBSD 4.0 released
Monday, 15 April 2013 13:48

OppBSD integrates essential parts of the real FreeBSD networking stack into OMNeT++ as a simulation model. Every simulated host (or router) runs its own copy of the FreeBSD kernel's networking stack. Consequently, the simulation model is very accurate, i.e., almost behaving like a real implementation. Release 4.0 works with OMNeT++ v4.3 (alternatively v4.1, v4.2) and provides IPv6 support. Presently, the package covers the full TCP/IP stack including IPv4, IPv6, UDP, TCP, ICMP, ICMPv6, ARP, ND, sockets and Ethernet frames. See the OppBSD website for download.

OMNeT++ 4.3 released
Wednesday, 03 April 2013 00:00

OMNeT++ 4.3 final version is now available for download. This release contains several bugfixes and usability improvements compared to 4.2.2. Among other improvements, indexing of big C++ projects got considerably faster and it is now possible to create scalar statistics from other statistic values. Read the ChangeLog (after the More link) to see the complete list what 4.3 has to offer compared to version 4.2 or go directly to the download page and test it.

INET 2.1 released
Monday, 04 February 2013 00:00
We are happy to announce the INET Framework 2.1 release. The INET Framework is an open-source communication networks simulation package for the OMNeT++ simulation environment. It contains models for several wired and wireless networking protocols, including UDP, TCP, SCTP, IP, IPv6, Ethernet, PPP, 802.11, MPLS, OSPF, and many others.  This new version is compatible with the the 2.0 version and contains only bugfixes and some additional components.

OverSim-20121206 released
Thursday, 06 December 2012 00:00

Ingmar Baumgart has announced OverSim release 20121206. You can download OverSim-20121206 from the download area of oversim.org.

These are the changes since the 20101103 release:

  • Compatible with OMNeT++ 4.2.2 and gcc 4.7
  • Complete rewrite of Pastry and Bamboo using OverSim's RPC interface
  • SimpleUnderlay: added optional tx queue for the destination access router (parameter enableAccessRouterTxQueue)
  • InetUnderlay now depends on unmodified INET-20111118
  • Many other bugfixes and enhancements (take a look at doc/ChangeLog)
 
Call for Papers -- 6th International Workshop on OMNeT++
Tuesday, 30 October 2012 21:43

The 6th International OMNeT++ Workshop will be held on March 5th, 2013 in Cannes, French Riviera. All submissions to the workshop should be of interest to the general simulation and modeling community, with OMNeT++ playing a key role. We welcome case-studies that employ OMNeT++ in the evaluation of new systems as well as contributions addressing general questions of simulation using OMNeT++. For model-centric submissions we encourage the publication of source code on the authors' website at the time of submission.

We invite two types of submissions:

  • Full and short papers of 4 to 8 pages answering open research questions, introducing novel simulation techniques, or addressing questions of accurate and efficient modeling for simulation.
  • Poster abstracts of 2 to 4 pages describing work in progress, provoking research questions in the context of the workshop, or code contributions that sketch the underlying model.

Submissions that are accepted and presented at the workshop will appear in the SIMUTools 2013 proceedings, on CD, in EU-DL, and in the ACM Digital Library (pending approval). Read the full Call for Papers

Submission deadline: December 8, 2012 23:59 UTC (firm deadline)

 
VEINS 2.0 released
Monday, 29 October 2012 00:00
The Veins project team have announced Veins 2.0, the latest version of their vehicular network simulation framework for OMNeT++. Veins is an open source Inter-Vehicular Communication (IVC) simulation framework composed of an event-based network simulator and a road traffic micro-simulation model, containing numerous improvements and new features.

This release continues the framework's six year tradition of providing a comprehensive set of high quality models for the simulation of Inter Vehicle Communication (IVC) to an ever growing user base; now spanning 5 continents, including universities, governmental bodies, and independent research institutes as well as most major European automobile manufacturers. 

Full source code, a beginner's tutorial, documentation, and the publication list are available at http://veins.car2x.org/
