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...

CALL FOR PAPERS: 1st OMNeT++ Community Summit
Thursday, 27 March 2014 10:20
The 1st OMNeT++ Community Summit (OMNeT++ 2014) is a one day workshop that will take place in Hamburg, Germany on September 2, 2014.

After six successful editions of the International Workshop on OMNeT++, we decided to change the workshop format to allow for less costs, more interaction between the participants, and more coding on-site. The successor of the International Workshop on OMNeT++ is the OMNeT++ Community Summit. The OMNeT++ Community Summit provides a forum for discussions on recent developments and novel ideas in the broad area of network simulation and modeling, with a focus on the OMNeT++ simulation environment.

The summit brings together developers and researchers to discuss applications and ideas on the important topics of integrating simulation models, coupling different simulation tools and providing more accurate and more efficient modeling approaches.

Paper submission deadline: July 4th, 2014

NETwork Attacks (NETA) Framework for OMNeT++ released
Tuesday, 28 January 2014 18:06
NETwork Attacks (NETA) is a framework devised to simulate attack behaviors in heterogeneous networks using OMNeT++. Due to the intensive research in the field of network security, with this framework we try to provide an useful tool to facilitate the estimation of impact, damage, of network attacks, and the development of possible defenses. This tool could have a direct use in demonstrating the effectiveness of defense (detection or response) techniques against network attacks or to compare the capabilities of different defense techniques among many other applications. NETA is a INET 2.1.0 based framework. Thanks to the versatile and extensible schema of NETA, a huge amount attacks could be implemented in each protocol layer. NETA tries to be a reference base tool for the network attacks simulation and implementation. It is delivered under GPL license for free use of the research community. 

NETA makes the network security simulation easier! Download the model now.

OMNeT++ 4.3.1 released
Tuesday, 17 September 2013 08:44
OMNeT++ 4.3.1 is now available for download. With this update, we made it a lot easier for first-time users to get started with OMNeT++: on the first startup, the IDE shows some useful bits of information, and also offers installing the INET Framework. In addition, the update also contains some bug fixes and smaller improvements to the Simulation IDE. There is no change in the simulation kernel and tools.

OS³, the Open Source Satellite Simulator
Wednesday, 14 August 2013 14:52
The OS³ (Open Source Satellite Simulator) model was ported to INET 2.1+ and is available on github. If you want to model satellite based communication, you will need accurate satellite mobility model.

OS³, the Open Source Satellite Simulator, was developed as a framework for simulating various kinds of satellite-based communication, based on OMNeT++. The aim was to create a platform that makes evaluating satellite communication protocols as easy as possible. OS³ is also be able to automatically import real satellite tracks and weather data to simulate conditions at a certain point in the past or in the future, and offer powerful visualization. 

Visit the GitHub repo. Note that the software's homepage still contains an older version of the model which is not compatible with the latest INET version.

Vehicular Networks Simulator (VNS) released
Tuesday, 07 May 2013 00:00

VNS is a high-performance simulator for vehicular networks. It was developed by Ricardo Fernandes at DCC-FCUP and Instituto de Telecomunicações | Porto, supported by the Portuguese Foundation for Science and Technology (FCT) under the doctoral grant (SFRH/BD/61676/2009). VNS is a simulation framework that completely integrates the mobility and network components in a transparent and efficient way, reducing the overhead of communication and synchronization between different simulators. VNS provides bi-directionally interaction between a microscopic mobility model and network simulators such as NS-3 or OMNET++. Visit the website.
