What is OMNeT++? OMNeT++ is a public-source, component-based, modular

and open-architecture simulation environment with strongGUI support and an embeddable simulation kernel.

OMNeT++ provides a component architecture for models.Components (modules) are programmed in C++, thenassembled into larger components and models using ahigh-level language (NED).

OMNeT++ is free for academic and non-profit use;commercial users must obtain a license from OmnestGlobal Inc.

System ModuleAn OMNeT++ model consists of hierarchically nestedmodules, which communicate bypassing messages to eachanother.The top level module is the system module.The system module contains submodules.Model structure is described in OMNeT++'s NED language.Modules that contain submodules are termed compoundmodules.simple modulesare at the lowest level of the module hierarchy

Windows Install OMNeT++ into a directory that doesn't have

space in its name, e.g. don't install in underC:\Program files\ (Otherwise you'll have problems

with the makefiles.)

Test OMNeT++ Windows users: Compiling OMNET++ applications from the command line

Click start button on your computer screen Chose run a small window will open: type cmdand click with the mouse on

OK, a command line window will open Change the directory to the current work directory (e.g.C:\OMNeT++\samples\queues)

1. Use the OMNET++ utility to create Makefile.vc [opp_nmakemake f ](willconsider all files in the current directory)

2. Add dependencies [nmake f Makefile.vc depend]3. Compile [nmake f Makefile.vc]

4. An executable program will be created which has the name of the directory(e.g. nim)

Every time you make changes to the files, first type [nmake f Makefile.vcclean], than repeat from 3 If you add files in the directory, you have to rerun 1, to create another Makefile.
