NS2 Visual trace analyzer

A Visual trace analyzer is been developed by Mr. Fernando and you can download freely from his website This software is been developed using
  • .NET C# 4.0
  • This software will run only in windows and not tested in Wine platform of Linux (May be will work)
This software accepts a tcl, trace files, scenario files and interprets the contents and displays results like throughput,data, etc.
Also there is a provision for graphing too.. Its a very great handy tool for NS2 (particularly beginners to researchers)..
Here are some of the screen shots of the software
Open a Tcl File and shows the second picture as shown in the next picture.
 In the following pic, the tcp packet flow is selected and a window pops out with various results.
Iin the following picture, the right side of the window is not used and the cross X indicates it is not used now, may be in future that area will be used.
And this picture tells you the throughput of a gives network.


  1. Sir, i am a new comer in scripting field and i need a script to do some calculation on the below given file data ....... please help me to write a shell script file based on the below file... it look like this.......

    c1 c2 c3 c4 c5
    s 0.398589568 _1_ MAC 0 (request send)
    s 0.513566459 _4_ MAC 0
    s 0.552966970 _0_ MAC 0
    s 0.787311440 _3_ MAC 0
    s 0.877323712 _2_ MAC 0
    s 46.46441059 _1_ MAC 0 (re-request send)
    s 47.59068956 _0_ MAC 0
    s 47.90057161 _0_ MAC 0
    s 47.98677431 _0_ MAC 0
    s 48.96975450 _0_ MAC 0
    s 48.9869547 _1_ MAC 0 (re-request send)
    r 49.0457547 _0_ MAC 1 (received request)
    s 50.058781511 _0_ MAC 0
    s 56.459210991 _3_ MAC 0
    s 66.986774311 _1_ MAC 0 (acknowledge send)
    s 67.020641218 _2_ MAC 6
    r 67.09610788 _1_ MAC 0 (acknowledge receive )
    s 68.073182951 _0_ MAC 0

    i want to write a script to which will help me to extract
    A) the maximum and minimum value of c2 when c1=s, c3=_1_ and c5=0.
    B) the minimum value of c2 when c1=r, c3=_0_ and c5=1.

    i want to do the delay calculation between two nodes... description of formula...
    node say n1(in my table it is _1_) send a request and time isT1... node n2 (in my table it is _0_) receive a request at time T2 and reply with an acknowledgement at time T3. the node n1 receive the ack packet at T4 time.
    Tint= T3-T2........
    formula is ------- (T4-T1-Tint)/2
    i will be highly grateful if anyone kindly do this to me. Hoping for reply me very soon. have a good day. Thanks.

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
$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…

nam installation - Segmentation Fault (Solved)

If you are encountering "Segmentation Fault" error while running nam in Ubuntu 14.04 or Linux Mint 17+ editions, this post will be helpful for you.

Download the nam file from this link

First, remove the nam which was installed earlier using the following command 

pradeep@localhost $] sudo apt-get remove nam

and install the new nam which was downloaded just now. go to the folder where the file was downloaded and issue the following command

pradeep@localhost $]  sudo dpkg --install nam_1.15-10_i386.deb

See the screenshot below to install and use nam

Installation of ns2 in Ubuntu 18.04 - NS2 Tutorial # 2

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. So this post and video tells you about the installation of gcc-4.8 version, then ns2 and then configuration.
Here are the steps, Please follow the video given below for more information.

$] tar zxvf ns-allinone-2.35.tar.gz

$] sudo apt install gcc-4.8 g++-4.8

if you have installed ubuntu just now, you can try these commands also in the beginning

$] sudo apt update
$] sudo apt install build-essential autoconf automake libxmu-dev

$] cd ns-allinone-2.35/ns-2.35
$] gedit
$] gedit linkstate/ls.h

line number 137, change erase to this->erase
$] cd ..
$] ./install

export PATH=$PATH:/home/pradeepkumar/ns-allinone-2.35/bin:/home/pradeepkumar/ns-allinone-2.35/tcl8.5.10/unix:/home/pradeepkumar/ns-allinone-2.35/tk8.5.10/unix
