Network Simulator 3

Network Simulator 3 (NS-3) is a software tool that allows researchers and engineers to create virtual models of computer networks. By simulating network behavior, it helps users test and analyze how different network configurations, protocols, and devices perform without needing physical hardware. This enables experimentation with network designs, troubleshooting, and performance evaluation in a controlled, cost-effective environment. NS-3 supports various types of networks, including wireless, wired, and mobile, making it a versatile platform for developing and improving communication technologies before real-world deployment.
