All about NS3

NS3. In this series, we’ll cover everything from the basics of NS3 to a deep dive into its code and logic. Get ready for an enlightening experience! Stay tuned for more updates. This is the first video in the playlist, where I discuss how to run a virtual machine on Windows, install NS3 (specifically ns3.37), and run your first code.

In this video, I explain the code of the first.cc file from the "examples/tutorials" folder. I cover how to execute the code, the steps you need to follow, and how the code in first.cc maps practically to the animation. By visualizing the code as I show you in the animation, understanding it will become much easier. I hope you enjoy this video!

In this video, I explain the steps for generating packet capture (".pcap") files. I use the "first.cc" file as an example and outline generalized steps that you can follow to easily generate ".pcap" files for any NS3 script. 

In this video,  I have discussed about the very famous NetAnim Utility in NS3 which is useful when we want to observe the animation of the previously executed simulations of NS3. I have mentioned the very basic steps to generate the ".xml" file and observe it in NS3. 

In this video, you'll be exposed to the actual power of NS3 simulator. We'll take the as usual first.cc file and we'll do some changes in code and then we'll observe the effect of changes being made. This video will be very helpful for those who actually want to explore this stuff in details. 

In this video, I discuss the second.cc file and its code. I explain the code in detail and explore various ways to run the file. 

In this video, I explain the third.cc file. I cover everything from the importance of moving the file to the "scratch" folder to using various utilities and making different observations in NS3. 

In this video, I discuss how to create a customized ring topology in NS3. We'll delve into the coding aspects in greater detail, starting with this first video where I explain the coding for a ring topology. 

In this video, I discuss how to create a customized ring topology in NS3. We'll explore the coding part in more detail, starting with this first video where I explain the coding for a ring topology. 

In this video, I discuss the Mesh Topology with 4 nodes. I cover how you can reuse the code from the basic point-to-point topology in the `first.cc` file to generate the code for a Mesh Topology.

In this video, I discuss the Star Topology with 5 nodes. I explain how you can reuse the code from the basic point-to-point topology in the `first.cc` file to generate the code for a Star Topology.

In this video, I cover the fundamental differences and explanations of UDP and TCP protocols. I provide a detailed explanation of simulating a basic point-to-point networking topology using the TCP protocol. We’ll explore the NS3 coding for this setup in the easiest way possible.

In this video, I discuss Trace Sources in NS-3, which are among the most useful features for advanced network analysis. Based on my experience, I share a basic understanding of Trace Sources and how they can be used to gather valuable insights and results.

In this video, I discuss the `fourth.cc` file, which demonstrates the basic approach to creating an application in NS3. We’ll explore applications in NS3, the need for custom applications, and how to write a simple custom application. Additionally, we’ll look at various ways to configure connections with Trace Sources. This video is crucial for beginners in NS3 and is a must-watch for anyone starting their NS3 journey.

In this video, we’ll dive into the `fifth.cc` file and explore how to attach and find trace sources. We’ll also learn how to combine trace sources with custom applications to hook them onto objects available at runtime and identify potential issues with connecting trace sources to these objects. This video will deepen your understanding of trace sources and custom applications, providing valuable tips for extracting the information you need from NS3. It’s a must-watch, so try to absorb as much as possible!

In this video, I explain how to run the `fifth.cc` file from the "examples/tutorials/" directory to observe the behavior of the TCP congestion control algorithm by analyzing the Time vs. Congestion Window readings. Make sure to watch the video through to the end to understand how to use the `fifth.cc` file and gnuplot for in-depth analysis and insights.

In this video, I explain the command line arguments in NS3 and how the `CommandLine` class simplifies their usage. This class is especially useful for managing complex scripts. Watch the video to learn how to automate and streamline your NS3 workflows effectively.

In this video, I discuss the `MobilityHelper` class in NS3, which allows you to set the mobility behavior of nodes while observing the simulation animation in NetAnim. It’s a good idea to watch the basics of using NetAnim first, and then continue with this video to explore how to integrate and visualize node mobility effectively.

In this video, I discuss how to assign random movement to nodes during simulation. To simulate and observe the effects of node movement on communication, you can use built-in mobility models, which simplify the process and keep things neat and effective. Let’s explore more mobility models and continue learning new techniques!

In this video, I’ll address a subscriber's question from the comments by explaining the importance of TCP. I will provide a detailed analysis of various test cases to illustrate its significance and functionality.

In this video, we’ll explore ways to run your NS3 scripts more easily and efficiently. This will help you speed up your workflow and simplify the process. Make sure to watch the entire video to get the most out of these tips!
