NS-2 Awk Scripts

HI all,
           Awk Programming is very easy to learn and simple to apply. Awk in NS-2  takes the trace file for analysis.
  • Handles complex task such as Calculation, database Handling, Report Creation
  • Each Filed is separated using Space(or Tab)
  • Record is separated using New-line character.
  • $1,$2,$3,$4 are used to access column.
  • $awk '{print $1 $2 "---> Rs." $3 * $4}' invent.tr  , here "invent.tr" be simple trace file act as input to awk to analyse . Quotes are used for printing purpose.
  • To print Entire record "$0"  -> $awk '{print $0}' invent.tr
  • Invent.tr consist of     values separated by space     like 10 20 30 40  . 
  • Here $1 =10 , $2 =20 .........
AWK in NS-2
   
          Awk programming can be used to analyse the metrics of any network connection
  •    Throughput
  •     PDF (Packet Delivery ratio)
  •     Jitter
  •    end-to-end Delay
  •     NRL (Network routing Load)
The general form of an AWK program is shown below:
BEGIN {<initialization>}
<pattern1> {<actions>}
<pattern2> {<actions>}
.
.
.
END {<final actions>}
 Execution Command  in NS-2 
  •  >> awk -f  filename.awk tracefilename.tr

    1. hi Hareem, Please use below link to Download ENd-2-End Delay

      http://www.mediafire.com/?z1c2cxdt1a31d

      Regarding Dropped packets !! its same as to calculate received packets and send packets .in the Pdf awk script replace the letter "f" or "s" or "r" with "d"
      f->forward packets
      r->received packets
      s->send
      d->drop packets

    2. Hello,
      What do you mean by in the Pdf awk script replace the letter "f" or "s" or "r" with "d" ?? Should i replace each and every f,r & s with "d" ?
      Can you please explain me how that works? Will it show me the number of packets dropped in the simulation/ad-hoc simulation?
      A quick reply will be highly appreciated my friend :)
      Thanks :)

    3. @suyash: Ns-2 used to create scenario files

      2. Creating node-movements for wireless scenarios.

      The node-movement generator is available under ~ns/indep-utils/cmu-scen-gen/setdest directory and consists of setdest{.cc,.h} and Makefile. CMU's version of setdest used system dependent /dev/random and made calls to library functions initstate() for generating random numbers. That was replaced with a more portable random number generator (class RNG) available in ns. In order to compile the revised setdest.cc do the following:
      1. Go to ns directory and run "configure" (you probably have done that already while building ns). This creates a makefile for setdest.
      2.Go to indep-utils/cmu-scen-gen/setdest. Run "make" , which first creates a stand-alone object file for ~ns/rng.cc (the stand-alone version doesnot use Tclcl libs) and then creates the executable setdest.
      3. Run setdest with arguments as shown below:

      ./setdest [-n num_of_nodes] [-p pausetime] [-s maxspeed] [-t simtime] \
      [-x maxx] [-y maxy] > [outdir/movement-file]

      Lets say we want to create a node-movement scenario consisting of 20 nodes moving with maximum speed of 10.0m/s with an average pause between movement being 2s. We want the simulation to stop after 200s and the topology boundary is defined as 500 X 500. So our command line will look like:

      ./setdest -n 20 -p 2.0 -s 10.0 -t 200 -x 500 -y 500 > scen-20-test

      The output is written to stdout by default. We redirect the output to file scen-20-test. The file begins with the initial position of the nodes and goes on to define the node movements.

      $ns_ at 2.000000000000 "$node_(0) setdest 90.441179033457 44.896095544010
      1.373556960010"

      This line from scen-20-test defines that node_(0) at time 2.0s starts to move toward destination (90.44, 44.89) at a speed of 1.37m/s. These command lines can be used to change direction and speed of movement of mobilenodes.

      Directives for GOD are present as well in node-movement file. The General Operations Director (GOD) object is used to store global information about the state of the environment, network, or nodes that an omniscent observer would have, but that should not be made known to any participant in the simulation.

      Currently, the god object is used only to store an array of the shortest number of hops required to reach from one node to an other. The god object does not calculate this on the fly during simulation runs, since it can be quite time consuming. The information is loaded into the god object from the movement pattern file where lines of the form

      $ns_ at 899.642 "$god_ set-dist 23 46 2"

      are used to load the god object with the knowledge that the shortest path between node 23 and node 46 changed to 2 hops at time 899.642.

      The setdest program generates node-movement files using the random waypoint algorithm. These files already include the lines to load the god object with the appropriate information at the appropriate time.

  13. Thanks Yuvraj sir!
    But can,t we directly use for pause time:
    setdest .
    because on reconfiguring like:
    ./setdest -n 50 -p 200 -s uniform -m 0.0 -M 50.0 -t 900.0 -x 1000 -y 1000 >scen-50
    I got a file scen-50.
    How to use this now?
    As I try to use set val(cp) "scen-50" but has no effect on performance.
    Please guide me with your knowledge.....

    ReplyDelete
  14. By directly means:
    Can we directly include pause time in tcl script:
    $ns at " $n() setdest "
    Is their any provision for adding field in it for individual nodes?

    ReplyDelete
    Replies
    1. $ns_ at 0.75 "$n2 setdest 379.0 349.0 20.0" ---> you can specify speed in the tcl file . Pause time is common for the entire simulator environment setup. thats why it declared only once in scenario file generation.

    2. Thanks Sir
      But on re configuring we get a text file.
      I named that file scen-50.
      How to use this file now in tcl?
      As I try to use
      set val(cp) "scen-50";
      & secondly
      set val(sc) "scen-50";
      both commands reflected no effect on performance.

    3. puts "Loading scenarios-05-25 file..."
      source "scenarios/scen-50"



      create one scenarios folder and keep scen-50 file in that folder and use above commands in ur tcl file

      Delete
    4. So if i have to vary pause time from 10 to 100 in steps of 10,
      i have to recompile using ./setdest command & create 10 different text files.
      Then keep them in a folder 'scenario'.
      That folder has to be kept in the same folder which also has the tcl file.
      Tcl files will now include
      puts "Loading scenario file..."
      source "scenario/"
      Please verify above steps.

    I have generated scenario for 30 adhoc nodes,
    Now I want to detect hidden terminal problem if any in the scenario & please suggest me the modification I need to carry out in my 50adhoc.tcl for removal of the hidden terminal problem.

  17. Possible Solutions To avoid Hidden Terminal Problem
    -------------------------------------------------------
    1) Increase the Transmission power in ut tcl file. set Rx_ "value" increase this power value.
    2) Move the nodes in ur environment setup. moving nodes can sense the carriers easily there by reduce the problem
    3) Use Omni Directional Antenna instead of Directional in ur tcl fine under antenna set up.

    One more question:
    About hidden terminal problem type I;
    If we created a topology of 500x500 of 100 nodes then most of the nodes will be in carrier sensing & transmitting range of each other.
    Then the problem is bound to occur I suppose?
    Am I right?

      For enabling energy , please check my post on energy module in NS-2. once u enable the energy model in NS-2 , the energy will be shown in joules in trace file. intially u hav to set the energy in joules in TCL file.
      For graph , run the scenario for 200 sec. change the group size like 10,20,30,40,50 and check the final energy after stoping the simulation . thus u can draw a graph between energy consumption and group size

      Better to simulate with TCL file instead << .sh file >> . thoguh u write .sh file , you should call the TCL file only. TCL file will produce trace file from which results can be analyzed.

      TCL ->TRACE FILE-> apply AWK scripts-> Results ->apply Xgraph -> graph as conclusion

      Please check ur trace file format and awk file u r using. the awk script is miss matching with ur trace file...use old trace file and try to execute. it will work 100 %

  31. Hi, Great site and very useful.
    I need an awk file for showing out of sequence packets arriving at a node. Have you got one or, if not, can you point me to where I might find one. Any help greatly appreciated,
    John.

      HI john , take Packet delivery node awk script and apply on ur trace file. check if its working or not. if its working , you just need to calculate for individual nodes. if u see the trace file . it will display the node number. in the condition , plz give the $(column num)==node number and calulate . increase the node numbers and calculate.

      Hi , the trace file u got was old trace file format. check the awk file, whether u can see something like $14 ,$20 ...if its like this then add $ns new-trace to ur tcl file and run.

      Please see my latest post :

  43. in the trace file of the vanet , they are the following layer : AGT-MAC-PHY
    to calculate the pdf, i m concerned with the AGT layer only, right ?

    so if i run ur awk :
    $0 ~/^s.* AGT/ {sendLine ++ ; }
    $0 ~/^r.* AGT/ {recvLine ++ ;}

    i get:
    cbr s:1001 r:15188, r/s Ratio:15.1728, f:0

    s > r ==> totally wrong, right ?

    where do u think is my problem?

    thank you so much
    you r helping me too much :)

      correct you should concern with AGT because its the APPlication layer which means the peer node will receive the packet successfully. MAC,PHY are middle layers were the format differs.

      You should replace cbr with DSRCApp in your awk file.

      Delete
  44. one more thing, on the net the format of the trace is :

    s 76.000000000 _98_ AGT --- 1812 cbr 32 [0 0 0 0] ------- [98:0 0:0 32 0]

    where 98 is the node ID.

    while in mine, it is :

    s 0.000067388 0 0.00 0.00 -99 0 0 AGT --- 0 DSRCApp 100 [0 0 0 0] ------- [0:0 -1:0 32 0]

    what is this 0 0.00 0.00 -99 0 0 instead of _x_ ?

    i m thinking of not caluclating the nb of received based on AGT but based on this weird nb also. what is ur opinion?

    here is a part of my trace file:

    s 0.000067388 0 0.00 0.00 -99 0 0 AGT --- 0 DSRCApp 100 [0 0 0 0] ------- [0:0 -1:0 32 0]

( cmd----> xgraph file1.txt ) . in this file give the x-axis(nodes) and y-axis(throughput) data in two columns like
      nodes(x-axis) throughput(y-axis)

      It depends on other parameters too. check out ur simulation timing, distance between the nodes, antenna model u r using, if the nodes are clubbed together then the delay will be less , check out the trace file format also

      highestAntennaZ_ ===> highest antenna position
      distCST_====> maximum receiving distance.

      consider the distance between the sender ans reciever is maximum . in this case , the distance between nodes may vary thus long distance nodes will discard the packets due to low transmission range. Transmission power(P_t)and packet Receving power(P_r) are calculated using propogation models in Ns-2. two way model,random point,shadowing models etc..u can also set the threshold physical layer using
      Phy/WirelessPhy set RXThresh_
      here 550.0 make sense in terms of range the nodes communicate

    i have no problem in awk or perl

    any clue?
    Thank you

  74. Hi! How can I set ns to simulate with 2 nodes. Only 1 node is the source and the other is a receiver node. I need to have the receiver node receive a total of 1350 packets. The length of the simulation time depends on the length of time the 1350 packets have been received. Therefore, I should not be setting the stop time. It depends on the simulation when the ns will stop.

  90. Hi, Great site and very useful.
    Sir,
    I need an awk script for showing out of routing path stretch between a source and a destination node (i.e., in terms of number of hops). Also, I need to examine each node in the simulation to figure out the ratio between the actual numbers of a node’s neighbors (i.e., neighbors in its transmission range) to those listed in the same node’s neieghbors-list. I’m working on GPSR routing protocol in NS2.
    Have you got one or, if not, can you point me to where I might find one. Any help greatly appreciated,
    Nashmi
