First of all we need a working NS-2.35, installed on Ubuntu-12.04/13.10/14.04. You can find the DIY on installation of NS-2.35 in Ubuntu-12.04 here and in Ubuntu-13.10/14.04 here . 2. Second, we need the Mannasim patch files for NS-2.35, which can be downloaded from here . I assume you have downloaded the "mannasim-NS-2.35.tar.gz" in '/home/ user_name /Documents' and have your NS-2.35 installed in '/home/ user_name /Documents/ns-allinone-2.35/'. Step 2: Integrating Mannasim with NS-2.35 1. Extract the downloaded Mannasim patch either using the right click context menu "Extract here" or using the following command from a terminal: 1 tar -xvzf /home/ user_name /Documents...
