OMNeT++ is a public-source, component-based, modular and open-architecture simulation environment with strong GUI support and an embeddable simulation kernel. Its primary application area is the simulation of communication networks, but it has been successfully used in other areas like the simulation of IT systems, queueing networks, hardware architectures and business processes as well. If you installed and successfully compiled the source distribution, the omnetpp directory on your system should contain the following subdirectories. (If you installed a precompiled distribution, some of the directories may be missing, or there might be additional directories, e.g. containing software bundled with OMNeT++.) The simulation system itself: omnetpp/ OMNeT++ root directory bin/ OMNeT++ executables (opp_run, nedtool, scavetool, etc.) include/ header files for simulation models lib/ library files images/ icons that can be used in network graphics doc/ simulation manual (PDF), readme, license, etc. manual/ Simulation Manual in HTML ide-customization-guide/ HTML version of IDE Customization Guide ide-developersguide/ HTML version of IDE Developers Guide api/ API reference in HTML nedxml-api/ API reference for the NEDXML library parsim-api/ API reference for the parallel simulation support tictoc-tutorial/ introduction into using OMNeT++ src/ OMNeT++ sources sim/ simulation kernel parsim/ files for distributed execution netbuilder/files for dynamically reading NED files envir/ common code for runtime user interfaces cmdenv/ command-line runtime user interface qtenv/ Qt-based graphical runtime user interface nedxml/ nedtool, message compiler, NED infrastructure layout/ graph layouting library scave/ library for processing result files eventlog/ library for processing event log files common/ common utility classes utils/ makefile generator and various utilities ide/ the OMNeT++ Integrated Development Environment misc/ various 3rd party contributions test/ regression test suite core/ regression test suite for the simulation library ... tools/ 3rd party tools and libraries bundled with OMNeT++ win64/ on Windows, contains MSYS tools and the MinGW-W64 toolchain macosx/ on macOS, contains various 3rd party libraries (e.g. OSG, osgEarth, Qt) Sample simulations are in the samples directory. samples/ directories for sample simulations aloha/ models the Aloha protocol cqn/ Closed Queueing Network ... The example simulations
The example simulations are designed to demonstrate many of the features of OMNeT++. We recommend that you try tictoc first, which also has an accompanying tutorial under doc/.
Please see the Install Guide, doc/InstallGuide.pdf for specific instructions for various operating systems, and to read about dependencies, optional packages and build options.
