plz help me in writing awk script for jitter or r u having it plz mail me . my mail id is india3005@gmail.com

Dear Mohit
hello sir
i am working on the adhoc routing protocol ,i used the protocol olsr and MP-OLSR,
i runing your script awk four calculate the end to end delay but i have this error
Average End-to-End Delay = -nan ms
can you give me an example of olsr awk because it is not the same forme!

thanks in advance.

dear Mohit
hello sir
may name is hanane, can you tell me how i Study the impact of network density on the performance of protocols OLSR and MP-OLSR , means in the X axis of graphe i have the number of noeuds and the Y axisof graphe i have the end to end delay for example.
i have the script.tcl ,my problem is how to calculate the end to end delay by contribution number the of the noeuds ????
please sir help me
thanks in advances

sir, i'm working with clustering in DTN... can u send me the coding...

HI
I want to draw curves with NS2.34 under CentOS 6.2 Please there’s someone there can give me the script to realize this task I can not use the xgraph
thanks for your help

sir your blog has been very useful in our project for comparing the performance of routing protocols AODV, DSDV and DSR in MANET's. I needed awk script to calculate end to end delay and packet delivery fraction at every instance of time.i have downloaded end delay and packet delivery fraction from your blog.. can u plz tell me wht changes should i maketo these files.thanking you in advance..waiting for your reply.

@Bhagath Singh - You can get that information from the following link:

http://neo.lcc.uma.es/staff/jamal/vanet/?q=content/vanetmobisim-ns-2-simulator

and the ns-2 code for VDTP is available on the following link:

http://neo.lcc.uma.es/staff/jamal/techwork_eng.html

@Spyware - That site is down now!

@Guna - AODV finds the shortest path based on the number of hops. See the following tutorial to understand the code of AODV in ns-2:

www-npa.lip6.fr/~rehmani/aodv_v2.pdf

Details regarding NEMO in ns-2 are available on the following link:

http://www.arcst.whu.edu.cn/web_kongrs/nemo_sim.htm

@Delali - Patches related to congestion control protocols for WSN are not widely available for ns-2. However, if I come across any such patch, I will post it here. Meanwhile, you can get some help from the Appendix Section of the following Master's thesis:

http://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&ved=0CGoQFjAD&url=http%3A%2F%2F194.42.16.6%2Faction.php%3Fkt_path_info%3Dktcore.actions.document.view%26fDocumentId%3D5444&ei=H1CrT6TCIIHLrQeC3rG_AQ&usg=AFQjCNHLLgh8WW3fgtLFB4kcicLih_CVrg

@Nehal - There are many factors that might affect your simulation results. Ensure that you have designed the topology as described in the paper that you are using, e.g.: what is the transmission range used by the authors, type of propagation model, queue size, etc. Unless you design the similar topology, it is not possible to obtain similar results.

See the following link for setting transmission range:

http://140.116.164.80/~smallko/ns2/range_en.htm

@Ashish - The following tutorial will help:

www-npa.lip6.fr/~rehmani/aodv_v2.pdf

@Pothalaiah - You need to execute AWK script on every trace file one by one. To reduce the time, you may design a shell script to this task.

@Prav - No it is not correct. AWK script to calculate throughput is available on the following link:

http://mohittahiliani.blogspot.in/2010/02/few-more-awk-scripts-for-ns2.html

Hope it helps.

Regards,
Mohit P. Tahiliani

@Suvodeep - After unzipping, you must apply the patch by using "patch" command. After the patch has been successfully applied, you must give ./configure

@Rama - See Section X of Marc Greis tutorial on the following link:

http://www.isi.edu/nsnam/ns/tutorial/

@Kay - All the files have been made available for download from the following link:

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

@Keepwalking - Your mechanism seems to be quite similar to LEACH. LEACH patch is available for ns-2.27. You can install that and make the necessary modifications.

@Suga - Sample TCL Scripts are available in the following directory which simulate WSN with 802.11

ns-allinone-2.xx/ns-2.xx/tcl/ex/wpan

@Sharad - AWK script to calculate delay can be downloaded from the following link:

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

@Priyanka - First you need to run the AWK script and redirect the output to another file. Later the following command must be executed:

xgraph filename.xgr

@Smita - Unfortunately, the OLSR official site is down!

@Babar - Better to use the "rate_" parameter of CBR rather than "interval_"
For multimedia traffic, you can use a rate of 64Kb and packet size of 200 bytes for interactive voice traffic. 640Kb and a packet size of 840 bytes for video traffic (Ref.: TCP Evaluation tool Manual).

@Mani - Following link explains simulating malicious behavior with AODV. You can use the same procedure to do it for DSR:

http://elmurod.net/index.php/2009/10/24/adding-malicious-node-in-aodv/

@Pare - You can download the AWK scripts from the following link:

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

TCL Script for energy is provided in the following directory:

ns-allinone-2.xx/ns-2.xx/tcl/ex

Name: wireless-newnode-energy.tcl

@Adarsha - Patch file is specific to a routing protocol. You can get few from the following link:

http://nsnam.isi.edu/nsnam/index.php/Contributed_Code

Hope it helps.

Mohit P. Tahiliani

@Jk - AWK Script provided on this blog cannot be used to plot a graph. It can be used to get the average values.

@Praveen - 1. Use GOD (General Operations Director) object to find the inter node distance.

2. See Marc Greis tutorial Section XI.2

3. Count the number of lines that get printed with COL in trace file. COL represents a packet drop due to collision.

4. Use xgraph, gnuplot or excel as per your requirements.

5. Make changes in mac/mac-802_11.cc file and recompile ns-2

@Katahatiku - Just use "ZRP" instead of any other routing protocol in wireless TCL Script.

@Josna - Use Xgraph, gnuplot or excel to plot it. Graph can be Queue size v/s throughput or Queue size v/s No. of dropped packets.

@Ashish - Modify the "struct" of AODV packet in aodv.cc. Include the field name, its length and an inline function to access it.

@Bhupendra - Read the above blog carefully. I have tried to make it as simple as possible.

@Sushil - Simulating a malicious node with AODV has been explained on the following link:

http://elmurod.net/index.php/2009/10/24/adding-malicious-node-in-aodv/

@Asmi - All scripts have been shifted to the following link long time back:

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

@Nithu - See the following link:

http://t-issariyakul.blogspot.in/2009/03/no-slot-error-for-classifiers.html

@Mcbain - genthroughput.awk cannot be used to plot graphs. It can be used only to get average values. Include an extra printf statement in genthroughput.awk within the loop so that it can be used to plot graphs.

@Jiya - Probably the trace file format will be different. Make sure you are using an AWK script corresponding to your trace file format. You can get some help from the following link as well:

http://140.116.164.80/~smallko/ns2/adhoc_routing.htm

@Engineer Ilyas - You can get some help from here:

http://t-issariyakul.blogspot.in/2010/07/segmentation-fault-common-error-in-ns2.html

Hope it helps.

Regards,
Mohit P. Tahiliani

@Meenakshi - There are different ways in which you can calculate jitter. For e.g. avgStats.awk provided on the following link provides 4 different ways in which you can calculate jitter. However, avgstats.awk works only for wired and new-trace format for wireless. The trace which you have posted shows that your trace format is an old one. Include the following line in your TCL Script

$ns use-newtrace

and then re-run it. After that you can use avgstats.awk to get the jitter values. Download trace2stats folder from the following link:

http://perso.citi.insa-lyon.fr/mfiore/data/trace2stats_v05b.tgz

@Hanane - Vary the number of nodes within the same area to study the impact of network density. To calculate the average end-to-end delay, you can use the AWK script provided in this blog. It is independent of the number of nodes. Make sure you use an AWK script with respect to your trace file format.

@Nisha - Get the code from here and follow the README file therein:

http://www.illuvatar.nu/ns-dtn/code/

@Nouran - Install gnuplot. It is a better tool to represent the results.

@Mitali - You need to cut the printf statement which appears in END part of the AWK script and paste it within the body of the AWK Script. Print two values separated by a tab - first one as time and second as the required parameter. Run the following command:

awk -f filename.awk filename.tr > filename.xgr

Later give

xgraph filename.xgr

or else you can also use gnuplot for better representation.

Hope it helps.

Thanks & regards
VMK

@Hamzah - I believe you can take the AWK Scripts provided in this blog and modify them according to your requirement. For measuring the handover delay, you may use the binding update packets which get printed in the trace file.

@Sanjeev - You can download it from the following link:

http://mohittahiliani.blogspot.in/2011/08/awk-scripts-for-normalized-routing.html

@Neha - Make sure the syntax "radius_" is correct. e.g. "_" must be there or not.

@Nouran - I have not come across such a design yet. Will post it here if any information is found.

@Ram - I think you need a TCL Script to do that. AWK script wont be useful for designing a scenario.

@Mitali - What is the error that you get with delay and pdf?

@Hasna - You should have 2 columns in your .xgr file. Did you modify AWK Script so that it prints according to a format required by Xgraph?

@VMK - AWK Scripts provided on this blog will not help you to plot graphs. They can be just used to obtain the values on the terminal. You need to modify them as explained above so that you can plot graphs.

Hope it helps.

@Poushali - C++ code of DSR is available in the following directory:

ns-allinone-2.xx/ns-2.xx/dsr

The TCL Syntax for running DSR is

set val(rp) DSR

But make sure you also include this line

set val(ifq) CMUPriQueue

instead of

set val(ifq) Queue/DropTail/PriQueue

Hope it helps.

N.venkatadri

can i have the tcl script for comparing any two topologies along with x-graph(star &ring if possible)

Hello Sir,
I need your help in generating TCL script for comparision of two topologies in NS2

@Radhika - I would recommend you to use "TCP Evaluation Suite" for calculating all those parameters. Try installing it and you are almost done because it provides a lot inbuilt facilities for extracting results.

@Venkat - May be you have to make some changes according to your TCL set up. Suppose if you are using UDP instead instead of TCP, please replace

$7 == "tcp"

by

$7 == "tcp" || $7 == "cbr"

and re-run the AWK Script.

Similarly, if your packet size is less than 512 bytes - make those corrections in AWK scripts and re-run. It would work fine! (assuming your trace file is of old format for wireless networks).

@Sajan - Use the TCL Script generator provided on the following link:

http://mohittahiliani.blogspot.in/2009/10/tcl-script-generator.html

Hope it helps.

hi sir,
i am working on associativity based routing protocol and i want to make it scalable so i need the tcl code for this. so please help me
thanks and regards

@Mahesh - To make a routing protocol scalable - you will have to focus more on its Core design. TCL script is just used for designing the required scenario. You can a standard TCL script provided on the following link for your work:

http://140.116.164.80/~smallko/ns2/adhoc_routing.htm

By using the procedure mentioned in the above link - you can generate as many scenarios as you want.

Hope it helps.

Hello, i liked your post very much it gives me an idea for my project. Can you please upload the files used above again coz the links to them are not working. I would really appreciate your help.

-Urmi

@Urmi - I cross checked all the links. They are working fine. Please let me know which link(s) are not working so that I can correct them.

Regards,
Mohit P. Tahiliani

mmm actually i could'nt find links to the above mentioned files ie energy.tc scen1.awk etc plz can u mention the link in the comment.
thnx
-Urmi

and the link given here for the energy consumption is not working..
http://mohit.ueuo.com/AWK_Scripts.html

@Urmi - The above mentioned filenames are just used for explaining the concept. There are no such specific files designed. You can alternatively use "wireless-newnode-energy.tcl" which is provided in the following directory:

ns-allinone-2.xx/ns-2.xx/tcl/ex

You can find almost all AWK Scripts (including the one for energy) on the following link (keep visiting this link for updates):

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

NOTE: Modify energy.awk as per your requirement. The script provided on the above link is designed for my scenario.

Hope it helps.

Regards,
Mohit P. Tahiliani

Thnx alot...
There is an example in ns2/ex/pgm. Please can you tell me how can i usse the energy model there. I am able to use it in DSDV, AODV etc but really stuck in this one.

@Urmi - Energy model is mainly required while working with Wireless scenarios. Whereas all the files in ns-2/tcl/ex/pgm correspond to Wired networks. I wonder why you need Energy model in Wired networks as they are not energy constrained.

Hope it helps.

Regards,
Mohit P. Tahiliani

ok actually i wanted to compare two wireless multicast protocols for energy efficiency. One is that i got, PUMA but i could not find any other i think MAODV is one but i am not able to run it. I have proficiency in c but with TCL and awk iam a begginer.Please can you suggest something.
Thnx
-Urmi

@Urmi - Yes, PUMA is available by default in ns-2.35. A script for the same is also provided in ns-2/tcl/ex.

Apart from MAODV - you can also take a look at CPUMA which is designed for MANETs and is based on PUMA. CPUMA's source code for ns-2.33 is available on the following link:

http://sourceforge.net/projects/cpuma/

Regarding MAODV:

MAODV's patch for ns-2.26 is available. Following are some useful links:

http://kunz-pc.sce.carleton.ca/Thesis/maodv-code.zip
http://kunz-pc.sce.carleton.ca/Thesis/maodv-scripts.zip
http://kunz-pc.sce.carleton.ca/Thesis/maodv-ns-2.26.pdf

and step by step installation procedure is explained on the link given below:

http://rahimanuddin.wordpress.com/2010/03/01/maodv-simulation-in-ns-2/

You can also try installing this code on ns-2.35, however, it needs to be done manually and line by line. Sample TCL scripts are also provided on the links above which you can use for your reference once the MAODV patch is applied to your ns-2.

Hope it helps.

I'm using ns2 for my project... I tried to execute xgraph and i got error in that..

awk -f delay.awk out.tr > out.xgr
xgraph out.xgr

Error is,

Error in file 'out.xgr' at line 3: Unknown line type
Problems found with input data

@Jothi Rajan - Did you ensure that delay.awk produces output in the format as desired by xgraph? Generally, the delay.awk should be designed such that it produces the output in two columns. Two columns correspond to X-axis and Y-axis.

Hope it helps.

Regards,
Mohit P. Tahiliani

hai sir,
I'm not cleared... Can u please give me sample program

@Jothi Rajan - I dont have one with me right now. You can download some of the AWK Scripts from the following link and modify them as explained above in my blog:

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

Hope it helps.

Regards,
Mohit P. Tahiliani

Hello sir,

Sorry for asking the same doubt again i understood what u have told.....
But while executing the delay program we will get only the delay of the packets na... but you are saying that we need to get in x-axis and y-axis (ie) simulation time vs delay is it right..
my doubt is how we get time while executing awk -f delay.awk > out.xgr ...... Please reply me sir these may be silly questions to you but as a beginner i'm confused with this concept for two days

@Jothi Rajan - Time is indicated in the 2nd column of the trace file. Hence, when you print $2 from your AWK Script - it will print the time.

You need to modify the printf statement in delay.awk. Presently, it is printing only one value i.e. delay. Modify it to print two values i.e. time and delay.

Example: printf("%d\t%d\n", $2, delay);

where, "$2" in the above statement refers to time and "delay" is a variable that keeps track of average end to end delay.

Hope it helps.

Regards,
Mohit P. Tahiliani

Hello sir,
Thank you for your reply.......... My another ques is i found some codings in your blog to find total packet sent , received , dropped and so on....... Is these are to be used for all packet transmission program to find the sent, received, dropped packets? If yes means how we execute it....

My another query is,
I'm getting error while executing throughput awk script as,
Begin {
'in expression:1: ^ invalid char'
please rectify this too

Thnx 4 replying, now as you said i should try CPUMA i downloaded the code but iam using ns-2.35. is there a way to patch it on ns-2.35?? or should i download ns-2.33 but then iam not sure whether PUMA will work on that???
plz guide me through this.

@Jothi Rajan - Your first query is not clear to me. Execution of all AWK Scripts is same as mentioned above in the blog.

Regarding calculation of throughput:

I recommend you to use "genthroughput.awk" provided on the link given below to calculate throughput.

http://mohittahiliani.blogspot.in/2010/02/few-more-awk-scripts-for-ns2.html

Note that "genthroughput.awk" works only for old trace file formats. If you have a new trace file format, use "throughput_newtrace.awk" provided on the link below:

http://mohittahiliani.blogspot.in/2010/03/awk-script-for-ns2-supporting-new-trace.html

@Urmi - PUMA's patch for ns-2.33 is available on the following link:

http://nsnam.isi.edu/nsnam/index.php/Contributed_Code#Multicast

The patch is provided by the same author who has integrated PUMA in ns-2.35

Hope it helps.

Hai sir,
Thank u for ur reply...... Please tell me whether there is a diff between 802.11 MAC and 802.11 MAC DCF (CSMA/CA)........ What is their difference and how they differ in codings.....
Whether MAC DCF is available as inbuilt coding or we need to add some lines codings to the MAC........

Sir I had also tried ur throughput awk script but it getting the same error........

Solve my problems

Hai sir ,

Please answer to this ques too.... I saw total number of sent packet awk script in ur blog in that coding u mentioned node_id as 0 to 6...... Is these are id's of the 6 nodes. If yes means then how i calculate sent packet of about 50 nodes for tcp.........

@Jothi - Yes, 802.11 MAC DCF is available in ns-2 by default. I recommend you to take a look at the ns-2 manual for more details on 802.11 MAC and its different types implemented in ns-2. Section 16.3 gives a brief idea about that. See the following link of ns-2 manual:

http://www.isi.edu/nsnam/ns/doc/node193.html

Regarding throughput calculation:

Please do not use throughput.awk. Use "genthroughput.awk" Get it from the following link:

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

If you still get errors, then the problem may be because either you are using a new trace format or the packet size in your simulation is less than 512 bytes. If you are using new trace format then use "throughput_newtrace.awk" provided on the link given above. If your packet size is less than 512 bytes - replace 512 in AWK scripts with your packet size.

For calculating total sent packets of 50 nodes:

Use "pdf.awk". It gives information about total sent, total received, total forwarded, etc. You can download it from the same mediafire link given above.

Hope it helps.

Hello sir,
Thank u very much for ur quite reply......... My another ques is i'm using ns2 in red hat linux through vmware workstation.... Is there any different format for executing xgraph for linux.... Because i had tried executing xgraph as u mentioned in ur blog but i'm still getting the same error as i mentioned u earlier... Please reply for this too

@Jothi Rajan - The command to execute xgraph remains same, irrespective of the operating system used. Try to run "xgtest.xg" which is available in the following directory:

ns-allinone-2.xx/xgraph-x.x/examples

The command to execute is: xgraph xgtest.xg

Check whether you get a graph or not. If not, probably xgraph is not installed properly on your machine.

Hope it helps.

Hi Mohit,
I use NS2.34 in Linux from wired network.
I want to calculate the end to end delay and packet loss
with awk scripts to realize graphs please help me if possible

Sir please help me with my last question..m stuck with my project..
-Urmi

@Urmi - I have not worked with CPUMA but I guess the changes that you have done are correct because thats the general syntax of executing any routing protocol. But still I would recommend you to see sample TCL script (if provided in the downloaded code) for the exact syntax of running CPUMA.

Another thing you can try is: Go in ns-allinone-2.xx/ns-2.xx and give the following command:

make install (you need to be in root mode to execute this command)

then try running the TCL script again.

@Nouran - Download the AWK scripts from the following link:

http://perso.citi.insa-lyon.fr/mfiore/data/trace2stats_v05b.tgz

Follow the instructions given in the README file to get results.

Hope it helps.

Mohit P. Tahiliani

is there any other multicast routing protocol in ns2 that i can use???

@Urmi - No, as far as I know, PUMA is the only multicast routing protocol for wireless networks available by default in ns-2.

Hope it helps.

Regards,
Mohit P. Tahiliani

To study multicast protocols for energy efficiency, suppose i have k number of nodes now i do simulation with two protocols on the same scenario. Now how do i see which one is a better one?? Do i calculate residual energy of each nodes?? or how do i proceed??

P.S i got the cpuma working thnx alot for your guidance.

hello Mohit P. Tahiliani Sir, I have done my simulation. i have generated dsr50_100 and scen50_100 and traffic files. Now how can i generate results for dynamic source routing from this .

now i am confused which results i have to shown for final work from these files and which parameters i have to take from these files for final results for dsr thesis. sir please help me

@Urmi - Design a scenario according to your application requirements. First run it with one protocol and take down the results. Then run the same scenario with another protocol and again take down the results. Now compare both the results and conclude.

@Surya - Once you have completed running the simulation - use parameters such throughput, delay, packet loss, routing load, residual energy, etc to analyze the behavior of DSR. AWK scripts of almost all these parameters are available in this blog.

Hope it helps.

Regards,
Mohit P. Tahiliani

I did a simulation using PUMA and i am gettin number of dropped packets as 0. That is a very ideal situation is there any parameter to control it??
Thnx

@Urmi - Try designing a different scenarios. Eg.: vary the speed of the nodes, increase or decrease the density of nodes, vary the number of multicast receivers, etc. It is not that PUMA will behave equally well in all the scenarios.

Hope it helps.

Mohit P. Tahiliani

hi sir,
can u pls help with it....
when working with awk scripts to find out pdf.awk etc, how can we write the output into a file?? like along with printing the output in terminal,i even want to write it in a file?? pls help..

I am Sreekanth Vakati doing my M.Tech in Andhra Pradesh. I am doing a project on MANET routing protocols.I have got some results like Packet delivery Ratio ,Routing Overhead,and Avg End-to-End Delay.I have got these results from Trace file run in the java parsetrace file.In my base paper the author calculated the Node Throughput.I dont have any idea to calculate throughput.Somebody told me that some awk files will be available in the net and run them in terminal,i have downloaded awk file and i don't know how to run it in Linux, if anybody know how to calculate the node throughput kindly give me the reply.

Good work Mohit sir this blog is very nice for a Person doing a project on NS2
One of my friends told me about your blog
its great

As a part of my project, I have made two more entries named Flag 1 and
Flag 2 in the existing neighbor table in aodv. Whenever a node X receive a
request from node Y, Flag 1 corresponding to Y will get set as "1". I want
to calculate the total number of entries in the neighbor table
corresponding to node Y, and the number of 0's set for the flag of Y out of the total number of entries. How can I access/ do this from the existing
neighbor table? Anyone who knows about this please help me. It was really
urgent for my project.
Thanks in advance

Sir, Most of the above links are not working..! From where i can get awk script to calculate the energy efficiency..! Please Help..!

hiii when m runni g xgraph i getting d error
"Parameter LabelFont: can't translate `helvetica-10' into a font (defaulting to `fixed
how to resolve???
should i need to dwnload smthng??i m using redhat linux 5 and ns2.35

dear sir,
can you tell me how to calculate residual energy of the node in ns2 ..how i can write tcl script for that.

Dear Mohit,
I want to know how to calculate reliability i.e. % of number of nodes that received data at the end of simulation in VANET new trace format of ns2.34

Hi sir... i am doing my master degree project now. i cant view graph wen i use this command xgraph out.xgr. i got error as following...
Error in file `out.xgr' at line 1:

Problems found with input data.
could u plz tell me ,why it is not working?

sir how to change the colour of the xgraph line while executing the .tr file...

sir,
i have downloaded awk files for pdr, genthorughput and instantjtter from ur page...and i have run the command awk -f genthroughput.awk mytrace.tr >out.xgr

how can i make graph...and what changes are need to b done in awk file ...i am using cbr traffic...
thanks you in advance ...

i want to show the three routing metrics (packet delivery ratio,overhead, delay) in ns2.35. i have tcl file about aodv and dsr. it is generate the nam file and trace file properly. but i do not run the xgraph. please sir, i want to know that how to run the xgraph and what command will be used for this. i am very much obliged if u help me.

how to calculate bandwidth in ns2 ?? Is there any awk script?

sir i am getting
Parsing error in event.
plz help me to solve this

sir i want the c++ code for routing table so that i can patch that will ns2

hello sir
i am creating xgraph but the graph's y axis values are not clearly visible.for .81 its taking it as 810.0000 * 10^-3.
Also tell can i save this plot somewhere??

please reply

hello sir I am doing project on vertical handoff between UMTS and WLAN so please sir suggest me about tcl code...

Do u require a different awk file to use with xgraph?

Hi Sir,
This is Hemanth. I am working on the comparison of Pattern Mac (P-MAC) and Short preamble Mac (X-MAC). How can i compare both in terms of packet delivery ratio, throughput and end to end delay. Number of nodes I consider is 100. Please help me out.
Thank you.

Respected sir,
I have simulated a wireless scenario with 50 nodes and DSR as routing protocol.I am finding it difficult to analyze my trace file. please help me out with this sir.
i hereby pasting the tracefile format of my results. Please help me to find out respective fields.

verry helpful .thanx

sir i want tcl script for sinkhole attack detection in wireless sensor network

I am doing the project on "Performance comparison of scheduling algorithms in Optical Burst Switched Network".
Can you suggest how to include obs-module in ns2?

hello sir
i want to plot two parameter graph for example scen2.awk of your example.but i didnt get scen2.awk .so please provide that i can study that for my parameters.

@Pinakini - I haven't worked on it and hence would not be able to assist you much on that.

@Anvika - There is no such file called scen2.awk. That name has been used for explanation only. I suggest you to use our APP Tool which helps in plotting graphs.

See this link: http://mohittahiliani.blogspot.in/2014/10/automated-post-processing-app-tool-for.html

Hope it helps.

hello sir

can you give me the awk script to calculating the energy consumption and network life time.

And can you tell me if we want to find packet delivery ratio for 25 nodes in random mobility.
Then we will have to find the pdr 25*25 times for each source and destination.

@Deepmala - You can try using APP Tool for analyzing your trace files.

Here is the link: http://mohittahiliani.blogspot.in/2014/10/automated-post-processing-app-tool-for.html

You can get energy consumption from that tool and PDR also. Network lifetime is not available in it.

Regarding your question on PDR - No! you do not need to do that. You can just find average pdr of the whole network.

Hope it helps.

Mohit P. Tahiliani

I have completed your simulator, but I have a question: if I use idsaodv to secure for this attact, how will I can do? Can you give me source file Tcl about idsaodv? tutorial? Please
Thanks so much!

Hello sir,
I have analyzed the tcl files in wpan folder of ns2.35.These are of AODV over802.15.4.The trace file of it do not contain 'AGT'.So it is not providing any output for most of the awk files provided by u.Please provide me some help regarding QOS Analysis of Zigbee(AODV over 802.15.4).

Thanks

@Pham - I do not have a sample TCL file for idsaodv.

@Smriti - That is because those TCLs may not be sending any data from the application layer.

I suggest you to change the AWK script as per your requirement.

Hope it helps.

Mohit P. Tahiliani

after obtaining value of parameters from awk file.i want draw graphs then can i use sh graph.sh command? & how?

@Anvika - Have you created a graph.sh file? If so, what does the code in that file do?

Regards,
Mohit P. Tahiliani

Is ns2 source code forclustering in aodv is available on net

Hello sir,

i have tried putting a node to sleep..i want to wake it up by pinging it using other node...give me some idea how to create tat scenario..i used ping commands in tcl script..but didn't work..please help me sir..

thank u

Sir
I would like to plot graph for PDR using xgraph. I am using the new trace format.I take time along x-axis and pdr along y-axis. But I dont know how to set values along x and y axes. could you please help me sir?

hello sir,
i need a energy efficient dsr.tcl file of 600 nodes please share me if you have one. That would be very helpfull. Thank you.

Respected mohit Tahiliani,
I, Sahil(student of ec engineering) pursing my final year project on performance comparison of AODV ,DSDV, DSR and ZRP in MANET. So, while working on ns-2.35 there are plenty of errors I am currently facing with. Firstly, when I try to fetch data from the AODV trace file via awk script which was downloaded from your blog, the script is executed and stores the output in a new file with shows that total throughput or PDR is "-nan"(I don't understand what is mean and so this dont match my expected outcomes). It would be thankful if you help me with this.
Thanking you,
Sahil

Ca anyone tell me how to plot SNR or BER plot in NS2
