NS2 and UBUNTU Installation on VMWARE

There are multiple ways that you can adopt to install ns2. As ns2 runs on the linux. so first you will have to install linux. You can install any distribution of linux fedora, ubuntu etc.

So, one way to do the installation is to first install this software called VMWARE. It creates a virtual machine which allows you to run operating system on another operating system just like any other application. Other ways include by installing Ubuntu direct from website using windows installer. Lets look at the first option.
