OMNET++ 4.1.1 INSTALLATION STEPS are listed below if you are looking for novel support from our developers. OMNeT++ is a robust, modular, and adaptable simulation framework that is extensively utilized for the development of network simulators and various discrete event simulation models. Its open-source nature, coupled with substantial community support and a comprehensive array of features, makes it particularly favored in academic and research settings. OMNeT++ offers a thorough environment for simulating intricate systems, including communication networks, wireless sensor networks, and vehicular networks. The framework employs a component-based architecture, allowing users to design reusable modules that can be seamlessly integrated into larger simulations. With its user-friendly graphical interface, extensive documentation, and compatibility with numerous extensions, OMNeT++ stands out as a preferred option for researchers and developers engaged in network simulations and protocol design.
Here, we have shared the required steps for the installation of OMNeT++ simulator.

2.System File Update Command:
First of all, we need to updates the list of available packages and their versions stored in the system’s package index. Use below command to update the system package.
Command: “sudo apt-get update”
Screenshot:
3.Essential Tools Installation Commands:
Command:“sudo apt-get install build-essential gcc g++ python python3 openjdk-8-jdk”
Screenshot:
If you get prompt to select [Y/n], then you must give the Y option to install all the package required for the above command.

INSTALL OMNET++ SIMULATOR:
We have to download the Omnet++ 4.1.1 under Any directory by the clicking the Link, it will directly download to Download Location and move the compressed file to the Any Directory that you need to install.
Link:– https://github.com/omnetpp/omnetpp/releases/download/omnetpp-4.1.1/omnetpp-4.1.1-src.tgz

2.Extraction of the omnetpp-4.1.1-src-linux file:
Next, we have to extract the compressed file, right click the file and click Extract here to extract the omnetpp-4.1.1 as folder in the OMNET++ Installation directory.

4.Launching the Terminal in the omnetpp-4.1.1 Folder:
In OMNeT++, “. setenv” command is used to set environment variables that can affect the behavior of the OMNeT++ simulation environment, such as specifying paths or configuration options. Next, we need to use the command in the terminal so launch the terminal in the OMNET++ Directory.
Command: “. setenv”

5.Set path for the omnetpp-4.1.1 Folder:
The command “gedit ~/.bashrc” opens the ~/.bashrc file in the gedit text editor. The ~/.bashrc file is a script that runs whenever a new terminal session is started in Bash, allowing you to customize your shell environment by setting environment variables, aliases, and functions.
Command: “gedit ~/.bashrc”
Screenshot:
After the usage of the command, we need to add following lines in the opened text File at the end of the file lines.
Command: “export PATH=$PATH:/home/ubuntu/omnetpp-4.1.1/bin
export LD_LIBRARY_PATH=~/omnetpp-4.1.1/lib”

6.OMNET++ 4.1.1 Configuration Process:
Next, we need to configure the OMNET++ packages that extracted and use command “./configure” command in OMNeT++ is a Mandatory step in preparing the simulation environment for building and running simulations. It checks for necessary dependencies, configures the build environment, and generates the Makefile needed for compilation. Running this command ensures that the system is correctly set up according to the specific requirements of OMNeT++, enabling a smooth installation and operation process.
Command: “./configure”

OMNET++ 4.1.1 Configuration Process Completed successfully.
7.OMNET++ 1.1 Compilation process:
Next, we need to compile the OMNET++ packages that extracted and use command “make” command in OMNeT++ is used to compile the source code after the configuration step has been completed. It reads the Makefile, generated by the ./configure command, and builds the project by compiling all necessary files and linking them together. This command is essential for transforming the source code into an executable program or library, allowing you to run and test your simulations in OMNeT++.
Command: “make”

OMNET++ 4.1.1 Compilation Process Completed successfully.
8.Launching OMNET++ 4.1.1 Simulator:
Omnet++ 4.1.1 is the latest version of the OMNeT++ discrete event simulation framework, offering advanced tools and features for modeling and simulating complex network systems. This version includes updates and improvements in performance, usability, and compatibility, making it more efficient for conducting detailed simulations of communication networks, embedded systems, and other distributed systems. Omnet++ 4.1.1 maintains its modular architecture, enabling users to create, reuse, and extend components easily, while also supporting a wide range of protocols and extensions for specialized simulations.
Here we will Launch the OMNET++ 4.1.1 IDE by using the below command.
Command: “omnetpp”
