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...

ReaSE - Realistic Simulation Environments for IP-based Networks
Tuesday, 02 September 2008 03:00

ReaSE is an open-source network simulation framework for OMNeT++. ReaSE is able to create realistic simulation environments with respect to hierarchical network topologies, self-similar background traffic, and attack traffic based on real attack tools.

The ReaSE framework provides a graphical user interface for generation of ned files including a realistic topology and necessary traffic generation entities. In addition, OMNeT++ and the INET framework are extended in a way that hierarchical routing and traffic generation are enabled within a user's simulation model.

ReaSE is developed at the Institute of Telematics, University of Karlsruhe. This tool is actively developed and open to feedback and contributions. If you have any questions regarding ReaSE, feel free to contact the authors.

Call for Papers -- 2nd International Workshop on OMNeT++
Wednesday, 13 August 2008 10:49

The CfP for the 2nd International OMNeT++ Workshop is now online! We are inviting you to Rome, Italy on the 6th of March, 2009, where members of the OMNeT++ community will meet to show off their work, exchange ideas, meet people of similar interests, and plan and coordinate joint efforts.

You can submit full or short papers (up to 8 and 4 pages). All accepted papers will be indexed, and selected papers will be considered for an international journal publication. The workshop will be held in conjunction with SIMUTools 2009.

Paper submission deadline (EXTENDED) is December 1, 2008.

1st International OMNeT++ Workshop
Thursday, 10 April 2008 14:27

The 1st International OMNeT++ Developers Workshop was held on March 7, 2008 in Marseille, France, with the purpose of bringing together OMNeT++ users and their tools, applications and ideas. Although there were OMNeT++ workshops before, this was the first peer-reviewed workshop, associated with a main conference (SIMUTools 2008). It was a successful workshop, with a number of high-quality papers (12) and posters (8) presented (chosen from above 30 submissions), with the number of workshop participants being above 40. You'll find more information and also photos in the Concluding Remarks here (pdf link).

A collection of links to the PDF versions of papers, slides and associated software is available on this Wiki page. If you are a workshop author, you are welcome to expand the page with more links (to slides, related project web pages, etc).

 
SimProcTC -- toolchain for remote execution of OMNeT++ simulations
Friday, 14 March 2008 12:11
SimProcTC is a model-independent, flexible and powerful tool-chain for the setup, parallel run execution, results aggregation, data analysis and debugging of OMNeT++-based simulations, using Open Source software under Linux. It optionally utilizes the Reliable Server Pooling (RSerPool) implementation RSPLIB for easily setting up simulation processing pools for distributed execution of simulation runs. Compared to other approaches like Akaroa, this RSerPool-based solution requires minimal configuration effort due to fully automatic configuration of the components. SimProcTC was developed by Thomas Dreibholz at the Institute for Experimental Mathematics, University of Duisburg-Essen.

U2Q - UML to Queueing Network
Tuesday, 29 January 2008 11:21

U2Q is a tool developed by Lukas Pustina at University Bonn. U2Q allows developers to estimate the performance of a system prior to prototypes, based on UML models only.

The tool implements a design methodology that allows developers to estimate the performance of a system in very early stages of development where no prototypes are yet available. Starting from a functional UML system model, the developer enhances the system model by incorporating performance annotations. From this performance aspects enhanced system model, U2Q generates Queueing Networks as performance models which then may be analysed using analytical or simulative approaches. The tool itself smoothly integrates into Telelogic Tau G2 3.1 and brings a command line version.

Documentation, screenshots and code is available from the web site.

 
ACID Sim Tools
Monday, 28 January 2008 10:59

ACID Sim Tools is an interactive and batch-mode simulation tool (and framework) developed by Anakreon Mentis, Panagiotis Katsaros and Lefteris Angelis at the Aristotle University of Thessaloniki for the performance evaluation of different combinations of concurrency control, atomic commit processing and recovery protocols (and protocol parameters), based on a minimal set of assumptions for an object-based computational model. The tool produces metrics that provide insight into the most influential performance and availability trade-offs that arise in distributed transaction processing architectures. Documentation and source code is available at their ACID web site.

The simulator will also be presented at SimulationWorks 2008 conference, which is co-located with the Simutools 2008 conference and the OMNeT++ 2008 workshop.

Announcing oProbe
Thursday, 29 November 2007 14:33
The simulation community has been accused for producing many simulation studies of bad quality. The mission of the oProbe open source project is to provide an instrument that produces statistically sound results at known quality. Stochastic sampling from a network of queues demands both confidence and correlation control. An important design goal is to be compatible with the OMNeT++ framework without introducing changes to this code, as well as making it easy for existing simulators to make use of oProbe. The oProbe project introduces a probe module, which is a new simple module in the context of OMNeT++. A probe is the instrument that applies a controlled stochastic sampling technique. The probe module may have any number of probes. The oProbe project supports different interface levels according to the functionality required. Based on the FIFO queue example included in the sample directory in OMNeT++, the oProbe project provides example code on how the software can be used by existing or upcoming OMNeT++ based simulators.
