Installing NS2 in Ubuntu 8.04 8.10 and 9.04

Step 1: Download NS2 from the following Website, I tried version ns-allinone-2.33.tar.gz.

Step 2: Put the file under /home/pradeep/ (my user login is pradeep, you may try with your username)

Step 3: go the folder in the shell prompt by issuing the following command cd /home/pradeep/

Step 4: Since installation of NS2 simulator needs some autoconfiguration files which will need to be installed. To download those packages, just execute the following commands $ sudo apt-get install build-essential autoconf automake libxmu-dev

it will take some time to download and install.

Step 5: Now execute the following steps so that NS2 will be installed

    tar zxvf ns-allinone-2.33.tar.gz 
    cd ns-allinone-2.33
    ./install

After the above three steps, NS2 will give the path information which needs to be set in the PATH variable

Step 6: Open the file .bashrc which is available under the folder /home/pradeep/ (if you try to install in root user /root/.bashrc). Use the following command to open the .bashrc file $ gedit /home/pradeep/.bashrc

Step 7: edit the above file and set the following paths over there

export PATH=$PATH:/home/pradeep/ns-allinone-2.33/bin:/home/pradeep/ns-allinone-2.33/tcl8.4.18/unix:/home/pradeep/ns-allinone-2.33/tk8.4.18/unix

export LD_LIBRARY_PATH= /home/pradeep/ns-allinone-2.33/otcl-1.13, /home/pradeep/ns-allinone-2.33/lib

Step 8: Thats it!!! save the file, logout and login with the username.

Step 9: open the shell prompt and type $ ns (you will get a % indicating that the installation is working correctly) $ nam ( a window will be opened showing the network animator)

ns2 installation in Ubuntu 18.04

Unlike earlier version of ubuntu, the 18,04 version does not support the direct installation of ns2, because of the latest C/C++ compiler (7.x), but the latest C/C++ compiler supported by ns2 is gcc-4.8.

AWK Scripts for NS2 to process data from Trace Files

AWK Scripts are very good in processing the data from the log (trace files) which we get from NS2. If you want to process the trace file manually, here is the detailHere is a sample of trace file from NS2 (However ns2 supports a new type of trace file also), but this post will make you understand the old trace format only.r 0.030085562 _0_ MAC  --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] r 0.030110562 _0_ RTR  --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] s 1.119926192 _0_ RTR  --- 1 message 32 [0 0 0 0] ------- [0:255 -1:255 32 0]
AWK Scripts are very good in processing the data column wise. For example
the first column in the above trace file represents r, s which indicates receive, sent respectively. If we want to trace the entire r and s alone from this trace file we can represent it as $1
So
$1 represents ACTION
$2 Time
$3 Node ID
$4 Layer
$5 Flags
$6 seqno
$7 type
$8 Size
$14 Energy (if the network nodes includes EnergyModel)To run the awk script in Li…
