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...

Castalia: A Wireless Sensor Network simulator
Tuesday, 05 June 2007 15:08
Castalia is a Wireless Sensor Network simulator for early-phase algorithm/protocol testing built at the Networks and Pervasive Computing program of National ICT Australia. It supports realistic channel and radio models, a key element for accurate early-phase WSN simulation. It provides support for defining versatile physical processes. It also supports enhanced modeling of the sensing devices and other often-neglected attributes of a WSN such as node clock drift. Download and documentation at: http://castalia.npc.nicta.com.au.
 
DYMO routing protocol for the INET Framework
Wednesday, 16 May 2007 15:44

Isabel Dietrich and Christoph Sommer from the University of Erlangen have implemented a model of the DYMO routing protocol for the INET framework and made it available under the GPL. You can download the model (plus examples and documentation) from the project download page which contains further patches to the INET Fw. The DYMO model will be included in future releases of the INET Framework.

C# Extension for OMNeT++
Sunday, 22 April 2007 11:55

The package CSharpSimpleModule has been announced, which makes it possible to write OMNeT++ simple modules in the C#programming language. The code is based on JSimpleModule. CSharpSimpleModule was developed by Andreas Lagemann, Distributed Systems / Operating Systems Group, TU Cottbus, Germany. This work is part of the SPP1140 "Basissoftware für Selbstorganisierende Infrastrukturen für Vernetzte Mobile Systeme" project of the DFG (Deutsche Forschungsgemeinschaft). [download]

Site reconfiguration, connection limit
Friday, 13 April 2007 10:49

Dear users,

Because of bandwidth abuse on the site, we were forced to limit the number of incoming parallel http requests from a single IP address to 3. This means that if you try to open more than 3 connections from the same IP address, you will get a Service Temporary Unavailable message from the server. This should not be a problem if you have your own IP address, however people behind NAT share a single IP. We are looking for a better resolution, but for the moment we think it is better to live with this limitation than having a nonfunctional site.

We are sorry for this inconvenience...

 
OppBSD 2.0
Wednesday, 14 March 2007 09:57
OppBSD is an effort to get the network stack of the actual FreeBSD kernel working in OMNeT++ as a simulation model. In the model, every simulated host (or router) runs its own copy of the FreeBSD kernel's networking stack, and every host (or router) has its own copy of all state variables of the FreeBSD kernel. Presently, the package covers the full TCP/IP stack including ICMP, ARP, sockets and Ethernet frames. It also allows one to dump internal kernel variables of the tcp control block (e.g., windows sizes, ssthresh, etc.) into an OMNeT++ vector file for later analysis and also provides to dump pcap files for analysis with standard tools like tcpdump or WireShark (formerly known as Ethereal).
 
Just another MF preview
Friday, 12 January 2007 01:00
Mobility Framework 2.0 preview 3 has been released. It mainly contains bugfixes for the 802.11 model. Additionally, the old manual of Version 1 has been added. Although parts of it are outdated, it might be still useful to get started with the MF. The new version can be downloaded here.
