What is OMNeT++?

OMNeT++ is a discrete event simulation environment. Its primary application area is the simulation of communication networks, but because of its generic and flexible architecture, is successfully used in other areas like the simulation of complex IT systems, queueing networks or hardware architectures as well.

OMNeT++ provides a component architecture for models. Components (modules) are programmed in C++, then assembled into larger components and models using a high-level language (NED). Reusability of models comes for free. OMNeT++ has extensive GUI support, and due to its modular architecture, the simulation kernel (and models) can be embedded easily into your applications.

Although OMNeT++ is not a network simulator itself, it is currently gaining widespread popularity as a network simulation platform in the scientific community as well as in industrial settings, and building up a large user community.

Check the screenshots if you are interested how the IDE and running simulations look like.

Components

  • simulation kernel library
  • NED topology description language
  • OMNeT++ IDE based on the Eclipse platform
  • GUI for simulation execution, links into simulation executable (Tkenv)
  • command-line user interface for simulation execution (Cmdenv)
  • utilities (makefile creation tool, etc.)
  • documentation, sample simulations, etc.

Platforms

OMNeT++ runs on Windows, Linux, Mac OS X, and other Unix-like systems.

The OMNeT++ IDE requires Windows, Linux, or Mac OS X.
