Installation of NS2 on Linux System（linux下ns2的安装）

Network Simulator 2 (NS2) is an open-source simulation package used for studying network traffic. It can be used to simulate a wide variety of computer networks, including wired and wireless networks, optical networks and Sensor networks. As a powerful and versatile tool, NS2 is widely used in wireless research. This article explains the steps of how to install NS2 on a Linux system.

To begin, we will start with the installation of supporting packages such as gcc, g++ and make. These packages are necessary for the installation and compilation of NS2. To install them on a Linux system, we can use the following command in the terminal:

sudo apt-get install gcc g++ make

Once the supporting packages have been successfully installed, we can now install NS2. To do so, we first need to download the NS2 package from its official website. After downloading it, change your working directory to the location of the NS2 package:

cd /path/to/location/of/ns2 
``` 

Next, we need to extract the NS2 package. To do so, use the following command in the terminal:

tar -xvf ns-allinone-2.35.tar.gz

Once the package is extracted, we can then start the actual installation process. To do so, use the following command:

./install

This command will install the NS2 buildup environment and then build the binary. Once the compilation is completed, the status “NS2 installation completed” will be printed on the screen.

We are now ready to use NS2 on our Linux system. To get started, simply run the following command:

ns

This will open up the NS2 main window, where you can start writing your simulation codes.

In conclusion, once you understand all of the steps, it’s relatively simple to install NS2 on a Linux system. While there may be some steps in between each step, they shouldn’t be difficult to understand. Now that you’ve installed NS2, you can start simulating your own wired and wireless networks.
