How to install ns 2.30 packages in ubuntu

To import NS 2.30 packages in NS2 if you encounter any uncertainties, we are prepared to assist you. Network Simulator 2 (NS2) is a prominent open-source discrete event network simulator. Initially developed by the VINT (Virtual Inter-Network Testbed) project, NS2 serves as a tool for simulating various network protocols, routing algorithms, and traffic models. Its capability to support both wired and wireless networks enhances its applicability for diverse research and educational objectives. NS2 provides researchers with the opportunity to explore intricate network scenarios within a controlled setting, thereby aiding in the assessment and comparison of network performance across varying conditions. Utilizing a scripting language (TCL) alongside a C++ based framework, NS2 allows users to design custom network topologies and analyze protocol behavior with comprehensive statistical outputs.
