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...

Host Identity Protocol (HIP) Simulation Framework for INET/OMNeT++
Monday, 01 February 2010 13:12

We are proud to announce the first public release of HIPSim++, which is a Host Identity Protocol (HIP) Simulation Framework for INET/OMNeT++, developed to provide a flexible toolset for testing and validation of HIP and its extensions. HIPSim++ is fully OMNeT++ 4.x compatible, and it is built on the top of the 20090325 version of INETwithMIPv6.

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.

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.
