Installing ns-3.37 and ns-3.35 in Ubuntu | Ubuntu 22.04 | NS3

Multiple Versions of ns3 in Ubuntu 22.04 In this post, we are going to install two versions of ns3 namely ns-3.35 and ns-3.37  My OS is : Ubuntu 22.04 LTS (Long Term Support) ns-3.35 uses waf and (./waf --run scratch/first)  ns-3.37 uses cmake  (./ns3 run scratch/first.cc) So we will install both the packages  Go through the video for complete instructions To start with  $ sudo apt update  $ sudo apt install build-essential autoconf automake libxmu-dev g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev  libxml2 libxml2-dev libc6-dev libc6-dev-i386 libclang-dev llvm-dev automake python3-pip libxml2 libxml2-dev libboost-all-dev  I have downloaded both the versions of ns3 fr

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 detail
Here 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 Linux,
gawk –f filename.awk filename.tr
So, it is necessary for the researchers to know the basics of awk scripts before they are used.
Here this post will let you know some of the scripts that were used to process the data (NB: all these codes were taken from various websites and you can refer those websites for further information).
To find the throughput of the Network
   1: BEGIN {

   2:        recvdSize = 0

   3:        startTime = 400

   4:        stopTime = 0

   5:   }

   6:    

   7:   {

   8:              event = $1

   9:              time = $2

  10:              node_id = $3

  11:              pkt_size = $8

  12:              level = $4

  13:    

  14:   # Store start time

  15:   if (level == "AGT" &;& event == "s" && pkt_size >= 512) {

  16:     if (time <; startTime) {

  18:              }

  19:        }

  20:

  22:   if (level == "AGT" &;& event == "r" && pkt_size >= 512) {

  23:        if (time >; stopTime) {

  24:              stopTime = time

  25:              }

  26:        # Rip off the header

  27:        hdr_size = pkt_size % 512

  28:        pkt_size -= hdr_size

  29:        # Store received packet's size

  30:        recvdSize += pkt_size

  31:        }

  32:   }

  33:    

  34:   END {

  35:        printf("Average Throughput[kbps] = %.2f\t\t StartTime=%.2f\tStopTime=%.2f\n",(recvdSize/(stopTime-startTime))*(8/1000),startTime,stopTime)

  36:   }

To print the Congestion window size


   1: BEGIN {

   2:  

   3: }

   4: {

   5: if($6=="cwnd_") {

   6:     printf("%f\t%f\n",$1,$7);

   7: }

   8: }

   9: END {

  10:  

  11: }

To print packet Delivery ratio


   1: BEGIN {

   2:         sendLine = 0;

   3:         recvLine = 0;

   4:         fowardLine = 0;

   5: }

   6:  

   7: $0 ~/^s.* AGT/ {

   8:         sendLine ++ ;

   9: }

  10:  

  11: $0 ~/^r.* AGT/ {

  12:         recvLine ++ ;

  13: }

  14:  

  15: $0 ~/^f.* RTR/ {

  16:         fowardLine ++ ;

  17: }

  18:  

  19: END {

  20:         printf "cbr s:%d r:%d, r/s Ratio:%.4f, f:%d \n", sendLine, recvLine, (recvLine/sendLine),fowardLine;

  21: }

    1. Did u set the LD_LIBRARY_PATH, you have to set it in the .bashrc file (ubuntu and fedora) and in linux mint (.profile) file.
      you have set the path like this
      export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/pradeepkumar/tracegraph202/bin/glnx86
      Change the username of your machine (my username is pradeepkumar), even you can give the above path inside the shell also.

  4. I am using the above file for calculation of throughput , but when i am running this for .tr files generated by AODV and LAR . Start time of lar is different than AODV , this is due to packet size parameter. if i remove this from awk file then throughput is different. even i am giving same simulation time in both the tcl files .
    Could you please help me in this regard


    could you please help me and tell me which file is to be used .
