1. Step 1: Installation and Setup

• Download OMNeT++: Initially, you should refer to the authorized website of OMNeT++ to acquire its current version. The version that you select must be appropriate to your operating system such as Linux/Unix, Windows, or macOS, so ensure that carefully.
• Install: For the installation process, adhere to the guidelines that are offered in the download settings. There is an installer specifically accessible for Windows OS. Retrieving files and executing a setup script or arrangement are the general processes included in the installation.

2. Step 2: Interpret the Basics

• Knowledge about OMNeT++: Interpreting the fundamentals of OMNeT++ frameworks as well as its elements such as channels, messages, and modules is considered as most significant before being involved in the simulation works.
• Learn NED Language: In OMNeT++, Network Description (NED) is the commonly utilized language for describing your network’s topology and elements. Note that learning the structure and syntax of NED is more important.

3. Step 3: Developing a Simulation Project

• Develop a Novel Project: To develop a novel simulation project, employ the OMNeT++ IDE. For your project, the essential directory layout and files will be arranged by this.
• Describe Network Topology: For describing the network topology as well as links, routers, nodes, and other major network elements, write NED files. After that, you need to set up all the elements or modules. The connections among them have to be defined.

4. Step 4: Drafting Simulation Code

• Implementing Modules: The activities of network modules that are described in your NED files must be applied through the utilization of C++. Managing events, specifying timers, and drafting the logic for the process of packet forwarding could be encompassed.
• Arranging Simulations: To arrange simulation criterion, including logging choices, simulation timeframe, and module-based arguments such as routing protocols or IP addresses, utilize the omnetpp.ini file.

5. Step 5: Executing Simulations

• Construct the Project: For creating feasible simulations, construct your project by employing the command line or from the OMNeT++ IDE.
• Execute the Simulation: From the command line or the IDE, run your simulations. A graphical runtime environment is the efficient platform that is offered by OMNeT++, in which you can observe the advancement of simulation and visualize your network.

6. Step 6: Analysis and Debugging

• Employ the Debugger: To advance your simulation, interpret the control flow and message forwarding, and explore arguments, use the combined debugger.
• Analyzing Outcomes: By including in-depth records of the simulation outcomes and events, the simulations of OMNeT++ produce output files. To retrieve performance indicators or rectify problems, these files can be examined.

7. Step 7: Visualization and Further Analysis

• Use Analysis Tools: In order to process simulation outcomes, OMNeT++ involves scripts and analysis tools. For creating statistical outlines, charts, or graphs of your simulation data, you can employ these tools.
• Tweak and Iterate: Sometimes, there might be a requirement to improve your network framework, append highest intricacy to your simulation, or adapt your simulation criterion on the basis of the analysis. If required, reiterate the simulation process.

How to run simulation in OMNeT++?

Numerous procedures are included in the process of executing simulations in OMNeT++. The procedures generally range from project arrangement and drafting the essential simulation files and configuration to construction and running of simulation. Based on executing simulations in OMNeT++, we suggest an explicit procedural flow to consider:

1. Step 1: Install OMNeT++

• First, it is important to ensure whether the OMNeT++ is installed on your system in an appropriate manner. In terms of your specific operating system, adhere to the proper installation instructions that are provided in the authorized website of OMNeT++.

2. Step 2: Develop or Open a Simulation Project

• Develop a Novel Project: Click File > New > OMNeT++ project in the OMNeT++ IDE. To develop a project by defining its name and location, comply with the guidelines. Based on your simulation requirements, you should select the kind of project such as a project utilizing particular frameworks (for instance: INET) or an empty project.
• Open the Previous Project: Instead of this, you can also open the previous project by clicking its directory in the project environment or by importing it within the OMNeT++ IDE.

3. Step 3: Draft or Alter the Simulation Model

• Network Description (NED) Files: In NED files, your network topology and elements have to be described. Definition of connectivity, arguments, and modules such as routers, nodes and others is commonly encompassed in these files. For your project, you can develop novel NED files or alter your previous ones.
• C++ Source Files: By altering or appending C++ source files, apply your modules’ activity and logic if tailored activity is required. For the simulations which need particular protocols or methods that are inaccessible in utilized frameworks, this procedure is considered as very essential.

4. Step 4: Arrange the Simulation

• Develop or Edit an INI File: In omnetpp.ini files, simulation arrangements are particularly defined. Global arguments, the network for simulation, logging choices, and module-based arguments could be arranged here. To execute the simulation, you can also choose particular situations and define the simulation time-frame.

5. Step 5: Construct the Project

• It is most significant to compile the project before executing the simulation. In the OMNeT++ IDE, click the Build button that is like a hammer icon. You need to make sure that you have no compilation bugs. To handle the project construction process, OMNeT++ utilizes the Makefile system. The essential C++ code will be compiled and connected with the OMNeT++ libraries by this system.

6. Step 6: Execute the Simulation

• Execute in the IDE: In the project explorer, you should right-click on the omnetpp.ini file and choose Run As > OMNeT++ Simulation for executing the simulation. By utilizing the arguments that are described in your INI file, this will initiate the process of simulation.
• Graphical or Command-Line Mode: To visualize the network and its variations, you can carry out the simulation execution in graphical mode. It is also possible to execute in command-line mode that is very helpful for long-running simulations or batch processing. Generally, while initiating the simulation or within the INI file, the decision can be made.

7. Step 7: Analyze the Outcomes

• Typically, different output files can be produced by OMNeT++ simulations and they are log files, vector files (.vec) for time-series data, and scalar files (.sca) for aggregate outcomes. To process and examine these files, employ exterior tools such as Python scripts, R, or MATLAB, or Analysis Tool of OMNeT++ IDE.

8. Step 8: Iterate

• Note that there might be a requirement for altering your simulation arguments or framework and repeating the simulation process in terms of the analysis. You can also enhance the preciseness of your outcomes and reinforce your framework through this cyclic process.
