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...

Featured Projects:

   INET Framework (Internet and LAN protocols)   INETMANET (mobile and ad-hoc networks)   Oversim (peer-to-peer networks)   Veins - Vehicles in Network Simulation    ReaSE (realistic Internet simulations)   MiXiM (detailed wireless simulations)   Castalia (wireless sensor and body area networks)   More...

New users: Watch the screencast for an introduction into the Simulation IDE, or see in the publications list what OMNeT++ has been used for. Check out some tutorials, browse the documentation, watch introductory videos, and explore the featured network simulation projects (click the logos above)!

GT-ITM Topologies for OMNeT++ and OverSim
Sunday, 20 December 2009 12:13
GT-ITM Topologies is a complete set of tools for the conversion of network topologies following the Georgia Tech Internet Topology Model (GT-ITM) to the InetUnderlay model used by OverSim. The provided tarball includes the GT-ITM topology generator, the BRITE topology tool patched with NED language support and the necessary updates to the ctopology.cc/h files of OMNeT++ for the support of weighted shortest paths.

This is a collection of already provided tools further enhanced to support the conversion of the topologies into an OverSim interpretable format (InetUnderlay). Apart from the topology structure, the created topologies provide support for routing policy weights and AS Number support, i.e. the simulation programmer can easily distinguish inter-domain from intra-domain paths.

OMNeT++ 4.0p1 released (for Linux)
Tuesday, 08 December 2009 10:40
We have created a patched version of the OMNeT++ 4.0 (called 4.0.p1), which works correctly with gcc 4.4.x. On some linux distros the IDE also stopped responding on first load because of incompatibilities with some versions of xulrunner (required by firefox). This version now should work without any problem on recent distributions. The windows version is not affected and the latest version is still 4.0.
 
Call for Papers -- 3rd International Workshop on OMNeT++
Tuesday, 06 October 2009 13:16

The CfP for the 3rd International OMNeT++ Workshop is now online. Come to Malaga (Spain) on March 19 2010, and meet other members of the OMNeT++ community to show your work, exchange ideas 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 2010.

Paper submission deadline is November 15, 2009.

  - GNP/NPS network coordinate system
  - Hotspot roaming model for simplegameclient
  - DHT: support for multiple entries with the same key
  - Underlays: Added support for asymmetric channels
  - Several API and INI FILE CHANGES - check your files!
  - Many other bugfixes and enhancements (take a look at doc/ChangeLog)

 
Castalia 2.2 released
Sunday, 16 August 2009 09:21
Castalia 2.2 was released on 14-8-2009. It implements most core features of the IEEE 802.15.4 MAC protocol that are relevant to Body Area Networks (i.e., single hop PANs with coordinator and beacons). Castalia 2.2 is a simulator for wireless sensor networks (WSNs), and it requires OMNeT++ 3.x.
 
Do we know about your papers?
Saturday, 15 August 2009 20:22
As you may have noticed, we have recently expanded our Publications database. First of all, it should now contain nearly all OMNeT++-related papers, from the beginnings until a few months ago -- presently over 400 entries! The database can be searched and filtered by words that occur in the title, authors, keywords, year, or abstract (yes, we store the abstracts as well, for better search results!). We have also added convenient "Web link" and "Search web for title" functions, so that you can find a copy and start reading as fast as possible. Entries are stored (and can exported) in BibTeX format.

Please help us make this database a useful reference! Check if it contains your papers, and if not, submit them. We are mostly interested in last years and earlier papers, because we'll periodically add the new ones by skimming various online databases anyway.
 
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.
