NS-3

NS-3 is a simulation tool used to model and analyze computer networks, like Wi-Fi, mobile networks, and data centers. It allows researchers and engineers to test network designs, protocols, and performance in a virtual environment before real-world deployment. By simulating different scenarios, NS-3 helps identify potential issues, optimize configurations, and predict how networks behave under various conditions—all without the cost or complexity of physical testing. It’s widely used in academia and industry to improve network technology and ensure reliable, efficient communication systems.
