Getting Started¶
In this tutorial, we show you how to build wireless simulations in the INET Framework. The tutorial contains a series of simulation models numbered from 1 through 14. The models are of increasing complexity – they start from the basics, and in each step, they introduce new INET features and concepts related to wireless communication networks.
In the tutorial, each step is a separate configuration in the same omnetpp.ini
file. Steps build on each other; they extend the configuration of the previous
step by adding a few new lines. Consecutive steps mostly share the same network,
defined in NED.
This is an advanced tutorial, and it assumes that you are familiar with creating and running simulations in OMNeT++ and INET. If you aren’t, you can check out the TicToc Tutorial to get started with using OMNeT++.
Try It Yourself¶
If you already have INET and OMNeT++ installed, start the IDE by typing
omnetpp, import the INET project into the IDE, then navigate to the
inet/tutorials/wireless folder in the Project Explorer. There, you can view
and edit the tutorial files, run simulations, and analyze results.
Otherwise, there is an easy way to install INET and OMNeT++ using opp_env, and run the simulation interactively.
Ensure that opp_env is installed on your system, then execute:
$ opp_env run inet-4.0 --init -w inet-workspace --install --chdir \
-c 'cd inet-4.0.*/tutorials/wireless && inet'
This command creates an inet-workspace directory, installs the appropriate
versions of INET and OMNeT++ within it, and launches the inet command in the
showcase directory for interactive simulation.
Alternatively, for a more hands-on experience, you can first set up the workspace and then open an interactive shell:
$ opp_env install --init -w inet-workspace inet-4.0
$ cd inet-workspace
$ opp_env shell
Inside the shell, start the IDE by typing omnetpp, import the INET project,
then start exploring.
