How do I create a project in OMNeT++?

Numerous processes are encompassed to develop a project in OMNeT++, that range from arranging the OMNeT++ platform to setting up and executing your simulation. The following is a general instruction that assist you to begin with a novel project in OMNeT++ in an effective manner:

Step 1: Install OMNeT++

1. Download OMNeT++: Initially, you should go to the OMNeT++ blog. Based on your operating system, download the suitable version.
2. Install: It is advisable to adhere to the installation guidelines that are offered in the package. Based on your OS, installation might encompass obtaining the archive and executing the installer or configure script.
3. Set Environment Variables: By means of establishing any environment attributes, the documentation or installer will direct you in the proper way.

Step 2: Launch OMNeT++

• By clicking to the OMNeT++ folder and executing the omnetpp executable, open the OMNeT++ IDE. You might identify a shortcut developed at the time of installation on a few of the frameworks.

Step 3: Create a New Project

1. Create Project: You should go to File > New > OMNeT++ Project, in the OMNeT++ IDE. Name for your project has to be entered and aim to choose a place when you want to convert it from the default.
2. Select Project Type: A kind of project should be selected. Generally, choosing an “Empty Project” could be an excellent starting point for learners, but when you need to investigate certain characteristics, you can also select from different instances.
3. Finish Setup: In order to finish the project arrangement, adhere to the remaining of the guidelines. Normally, regarding the inclusion of assistance for characteristics such as INET for network simulations the expert will ask, which you could encompass on the basis of the requirements of your project.

Step 4: Create a Simulation Model

1. Add a NED File: Typically, the network topology is described by Network Description (NED) documents. In the Project Explorer, right-click your project and choose New > Other > OMNeT++ and select NED File. You must specify a name to it and finally click Finish.
2. Define Components: Describe your network elements such as links, nodes, etc in the NED file. The following is a basic instance:

network SimpleNetwork

{

    submodules:

        node1: StandardHost;

        node2: StandardHost;

    connections:

        node1.ethg++ <–> { delay = 100ms; } <–> node2.ethg++;

}                   

1. You have the INET model installed and are employing its StandardHost element are considered in this instance.
2. Add a Configuration File: By right-clicking the project and selecting New > File, develop an omnetpp.ini file to arrange your simulation. In what way you might arrange the simulation for the SimpleNetwork is given here:

[General]

network = SimpleNetwork

**.node1.numUdpApps = 1

**.node1.udpApp[0].typename = “UdpBasicApp”

**.node1.udpApp[0].destAddresses = “node2”

**.node1.udpApp[0].destPort = 1000

**.node1.udpApp[0].messageLength = 100B

**.node1.udpApp[0].sendInterval = 1s

1. A fundamental UDP application is created by this arrangement on node1 in order to send messages to node2.

Step 5: Build and Run the Simulation

1. Build the Project: In the Project Explorer, right-click your project and focus on choosing Build Project.
2. Run: After developing the project, once again right-click your project. Then select Run As > OMNeT++ Simulation. This step opens the OMNeT++ simulation runtime platform, where you are allowed to execute and communicate with your simulation.

Step 6: Analyze Results

• To visualize and examine the outcomes of your simulation, focus on utilizing the OMNeT++ IDE’s analysis tools. The packet flows, network topologies, and statistical data produced by your simulation can be observed.
