Hi, do u have awk script for new trace wireless format of average end to end delay? thanks!

Yes I have AWK script for average end-to-end delay supporting new trace format. I will upload it on blog soon. Thanks for your co-operation.

hi, could you post awk script for total transmitted packets (control packets + data packets) too? because i need these for my project, hope you can help, thanks!

Hi,

I tried your awk file for throughput, throughput_newtrace.awk.

But I keep getting this output with my trace file:
Average Throughput[kbps] = -0.00 StartTime=400.00 StopTime=0.00

Do you know what the issue is. any help would be appreciated.

I am using ns-2.29 and the routing protocol aodv.

@Nourideen: Please check you are using the same transport protocol which is used in the awk script. If not please change it to the one you are using.

Hope it helps.

Hi Mohit,

I am doing simulation of WSN in ns2. I need to find the packet loss due to congestion occurrence in WSN and calculate the energy consumption for transmitting sensors packets. Do you have an awk script for doing that?

Thanks in advance for you help.

Hi Mohit,

Sorry, I forgot to mention that I am using the new tracefile format.

Any help will be highly appreciated.

Sorry sir,

Im new to ns2. could u tell me where to write awk script?

im using cygwin to run my simulation.

Please help asap

@Albrwaqi - You can write it in any editor. However make sure you save the file with .awk extension and it should be saved in unix format.

Hope it helps.

please send me the awk script for latency and capacity for new trace file format...my mail id is ssnsharath@gmail.com ....thank u...

in my trace file,the send 's'packets is less compared to receive 'r' packets..it means that received packets is more than send packets which is not possible in practical scenario...it is in old trace file format..im using ns-allinone 2.28...please reply me what mistake would i have done....thank you..my mail is ssnsharath@gmail.com

@Sharath - Receive event "r" happens for two reasons - (1) if a packet is sent from Application layer (AGT) down to Routing layer (RTR), it shows "r" in the trace file. Note that this occurs in the SAME node. (2) if a packet is received from neighboring nodes, it also shows "r" in trace file.

Make sure you do not calculate the "r" events which are due to (1).

Hope it helps.

hi mohit, thanks alot for your help. i am doing coparison of energy consumption of dsr and aodv, please help me to find a suitable awk command to analyz my trace file. tanks alot

Thanks for ur help..im doing project in sensor networks..simulation time is 600 seconds and by deploying 100 nodes.im getting the value of send packets as 21,00,000 and received packets as 18,00,000..is it correct?..if so please tell the reason?..also is there any possibility to reduce the number of packets since in sensor networks,that much packets wont come know?...please reply..Thanks a lot..my id is ssnsharath@gmail.com

@Mehdi - Energy parameter in old trace format gets printed in 14th column of the trace file. You can create a simple AWK script that prints the value of this parameter for all the nodes that you require.

@Sharath - It is difficult to verify the results without knowing the exact details of scenario. Yes, the number of packets generated can be reduced by changing the value of interval_ parameter of CBR.

Hope it helps.

sir,Thank you for ur help.my project is analyzing the interaction of STEM and SPAN topology schemes..i have combined STEM and SPAN..but my problem is that i don't know how to set the wake up period and find latency per hop as given in my STEM base paper titled "STEM: Topology Management for Energy Efficient Sensor Networks"..for reference, please download the STEM paper..it will be available in pdf format...i want a graph for my project similar to that given in figure 5 in that STEM paper...so please guide me how to vary the wake up period and obtain latency per hop...i will be greatful to you if you please check it and send me...i know its a huge task but please help me out sir...also if you have ns2 code for STEM paper ,please send it to my mail id sharathprem@gmail.com..waiting for your reply...i will be really thankful to you sir....please see it..Thank you

sir,please reply to my previous query which i asked you.i also have another query now.please do reply to this also.sorry for disturbing you a lot...
what is the cbr packet rate,packet size, packet interval parameters which we have to set for a basic wireless sensor network simulations?just the standard value of parameters for sensor networks in ns2...please do reply sir..Thank you a lot....

Hi! do you know how to put in a file tcl commands from a file awk? thank you

Hi Mohit,

I havent tried your tcl or awk scripts yet. Since i am using the NS 2.34 version i wanted to know whether these scripts for the new version as well.

Also to generate the xgraph ( say for throughput) what after we run
$ns myprogram.tcl run

Any help will be highly appreciated.

Thanks

Thanking you in anticipation and anxiously waiting for your reply.

can u say the explanation for this trace format.... D-drop next everything what?

@P - Cut the printf statement which is given at the end of the AWK script and place it inside the loop so that at every instance of time it prints the value. Moreover, make sure you print atleast two values (e.g. time and throughput) in that printf statement.

@Aws - Latency = end to end delay. End to end delay of entire system is called average end to end delay. You can take a sum of delay of three flows and divide it by three to get average end to end delay.

@Group18 - I will try to do it by next week. Thanks for your co-operation.

Hi Mohit,

Thanks for your reply. I am doing simulation with an attack node. I have used the code from http://elmurod.net/?p=196 to add malicious node and drop packets. but now I need to introduce malicious node in DSDV/DSR. can you please help me getting the code and where exactly I need to place the code????

@P - I have not come across any material that can help in modifying DSDV/DSR for simulating malicious nodes. However, I strongly believe that you can modify DSDV/DSR using the same link though it demonstrates modifications for AODV. If I come across any good material I will post it here.

Hope it helps.

Hi there , I'm actually doing a comparaison between OADV and DSR routing protocols ..and I need a awk scripts witch caculate some metrics values ( like :
-Packet Delevery Ratio
-Average End to End Delay
-Dropped packets
-Routing Load
-Average Path Length
-Normalized Routing Load

Can you help me pleaseeeeee ? did you already post them somewhere ? if Yes where ? Thank you a lot : ) !!

Sir i need to implement OLSR and DYMO routing protocols in NS2 but it seems that NS2 do not support these protocols... Also it is said that NS2 supports TORA protocol but when i use the code generated by nsg.jar i get an error executing the tcl script.. but the codes generated for AODV,DSDV and DSR works fine... Can you help me overcome these problems?

Thank you Mr.Mohit I really appreciate your helps.

Only one request remaining..can you please make your modification on the following script in order to calculate throughput instead of goodput, i think throughput not the same as goodput, ain't it?

# determine the time the first packet was sent
set start = `egrep "^s .*\-Nl $layer " $tracefile | head -1 | gawk '{print $3;}'`

# use number of bytes received over the last interval to calc
# interval b/w
egrep "^r .*\-Nl $layer " $tracefile | \
gawk -v start=$start -v base=$start -v step=$interval -v outfile=$outfile '{ \
time = $3; \
while (time > base) { \
bw = bytes/step; \
if (max < bw) max = bw; \
printf "%.9f %.9f\n", base, bw >> outfile; \
base += step; \
bytes = 0; \
} \
total_bytes += $39; \
bytes += $39; \
} END { \
step -= (base - time); \
bw = bytes/step; \
if (max < bw) max = bw; \
printf "%.9f %.9f\n", time, bw >> outfile; \
if (total_bytes) \
printf "%.3f", (total_bytes/1024.0)/(time-start); \
else \
printf "0.0"; \
#printf "Max Goodput = %.3fKB/s\n", (max/1024.0); \
}'

dear Mohit,
in end to end delay script for wireless in new trace file format der is no sequence number column in my trace file...so im findin it difficult to create a new awk file from ur old one...

Hi Mr.Mohit, I read in wikipedia at (http://en.wikipedia.org/wiki/Goodput) there are many differences between measuring goodput and throughput. unfortunately I couldn't modify my script by myself because I'm beginner in this field..

I don't know where should I do the required modification in my script. I observed that my script is written as tcsh script without file extension as your AWK script (script.awk), is it quite different?. also my script is called from file.sh by using this command:

set goodput = `wlan-goodput audio-video-Bt.tcl 0.5`

But I don't know how to use your script instead.

Anyway, please if you can help me in this regards, I'll be very thankful for you.


Best regards,

Hi Mr.Mohit, I couldn't modify my script in the previos post, it quite different from that you proposed..please help me.. I'm using a new trace format..if u need to look at my trace file, I've uploaded it at:

http://www.mediafire.com/?cggi7wezi3fj7wk

Thank you in advance
Best regards,

@Ankush - New trace format has sequence number field. See the following link:

http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats#New_Wireless_Trace_Formats

If your trace file is not in this pattern then it is not a new trace format.

@Aws - While calculating throughput we take retransmitted packets also in the consideration whereas for goodput - retransmitted packets are not considered. Hence the modifications required in my genthroughput.awk will be such that if there are two packets with same sequence number (one original and one retransmitted) it should be considered only once (retransmitted one is not counted). Thus include a condition in my AWK script such that if you have counted a packet once when it was transmitted originally, do not count it again when it is retransmitted.

Hope it helps.

Regards,
Mohit P. Tahiliani

while running the throughput script i am getting
Average Throughput[kbps] = -0.00 StartTime=400.00 StopTime=0.00

I got the result for AODV but not for DSR

you told above to change the routing protocol in awk script. but i am not getting where to change it...

dear Mohit,

please help me to crate the Xgraph from trace files using awk script.

with the commands:-
awk -f awkscript.awk tracefile.tr > xgraph.xgr
xgraph xgraph.xgr
I am doing my work.

but my problem is that my xgraph.xgr file is as following:-
1.0000 0 0 0
2.0000 0 0 0
3.0000 0 0 0
4.0000 0 0 0

means last 3 columns are all 0 so that i am getting the xgraph with a straight line.
please help me!!

@Shweta - No you do not have to change routing protocol since there is no such column in genthroughput.awk. You need to verify whether the TCL script with DSR is simulating correctly. Also see the packet size is same for scenario of AODV and DSR or not.

@Abhishek - Your AWK script may be printing incorrect columns from the trace file. Verify whether its printing the columns that you need.

Hope it helps.

Mohit P. Tahiliani

Hi Mohit,
Can you give me some help in simulating mobile WSN in NS2. Also some help in Geographic Routing. I am working with ns2.34

thanks in advance.

@Sandhya - What is the error you are getting while generating throughput? To know how to generate graphs please visit my another blog named "Xgraph and AWK Scripts in NS-2"

@Amitpal - You may try using some sample TCL scripts provided in the following directory:

hello sir,

please give me the awk file for olsr tcl script...
ramkrishna.appu@gmail.com

hello mohit !
I have removed all the errors from tora.cc and tora.h and recompiled it...
Now, no error is coming.... but none of the node out of 6 is transferring the packets.. what could be the reason ?? Date of submission is coming closer...

@Ram - AWK Scripts provided in this blog are general and can be used for almost all routing protocols.

@Shruti - There can be many reasons:

They are not in communication range.

Transport agents are not correctly attached with respective nodes.

Applications are not correctly attached with respective transport agents.

Check your TCL script for logical errors.

Hope it helps.

Regards,
Mohit P. Tahiliani

@Mohit - Is this error related to tora.tcl file or tora.cc file/Imep.cc !!
because tora depends on IMEP protocol for transferring packets...

@Shruti - If its a .cc file error it should pop up the error while compilation. There can be few logical errors in .cc file as well but chances are less (since you have just corrected errors in .cc file). Check the traffic generation commands in TCL Script.

Hope it helps.

Hello Mohit ,

I have 3 nodes sources, a one base station and 3 mobiles nodes .
a duplex link between first source and base station .
a duplex link between second source and base station .
a duplex link between third source and base station .
... they 3 nodes mobiles attached to base station .

I wanna get dropped packets , So, I increase they traffics in CBR . i get dropped packets in they source nodes .

Please, I want to change dropped packets in the node base station .

How I can do this ? It need agent or what ?!

thanks you in advance !
Please , how I can to this ...

@Afif - You can download the AWK Scripts for throughput, delay, etc from the link given below:

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

AWK Script for calculating routing load is available on the following link:

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

@Hajjaji - You are getting packet drops at the sources because the "interval_" parameter of CBR is not set correctly. Do not use the default value of "interval_" because it is very less and generates more packets than the source's queue size.

Increase the value of "interval_" to avoid packet drops at the source.

Hope it helps.

Hello Mohit,

I couldn't download the script for new trace file (throughput). is the link broken?? Kindly help me with this soon...

THank you very much for your guidance!

@Afif - Yes you can use AWK files which I mentioned in my previous reply for the trace file which you have shown. Explanation of the trace file is provided on the following link:

http://www.cs.binghamton.edu/~kliu/research/ns2code/#trace

@Stud17 - You can download it from the following link:

http://www.megaupload.com/?d=DRPN6R4U

Hope it helps.

Mohit,

I tried running the new trace. But I get this output with my trace file,

Average Throughput[kbps] = -0.00 StartTime=400.00 StopTime=0.00

I read the previous posts that discusses the same problem (about routing protocol). But I didn't get where to make the required changes. I work on example.tcl file on hcca patch. This tcl file doesn't mention any routing protocol. I am wondering where and how to resolve this issue. Kindly do let me know..

Thanks in advance!

-Chithra

Hello,

I noticed that packet size is different from the trace file. In awk script it is 512, whereas trace file has different pkt size(160 & 180). I replaced "512" as "159" in the awk script and now i get the following output,

Average Throughput[kbps] = 254.44 StartTime=20.00 StopTime=99.98

Am not sure whether I did it correctly. Kindly let me know it is correct or not?

I believe the one am currently using is for the whole network. I am interested in calculating the throughput from node to node. Can you provide me script for that??

Looking forward for your reply..

Thank you

Sir i am using ns2.29+in windows.I want to simulate wireless mesh network.
1)Is it possible with ns 2.29?Any patch is available?
2)Am I able to change AODV trace format as my own wish?If so where I have to modify?
Could you please clear my doubts?

Thank you Sir

Hello Sir,

I wanna calculate end to end delay for my wireless scenario (uses new trace format).. Can you provide me scripts for that?? In one of the above posts you have mentioned to modify the column no. (from the old trace format). But I couldn't figure out exactly where and what exactly goes into the script?? Your help is highly appreciated... Kindly assist me..

Thanks!

@Chithra - Yes, the modification which you have made by changing packet size is correct. I have used 512 since majority of the simulations use packet size 512 or above.

If you are interested in finding throughput of every connection, you may have to modify the AWK Script by taking into consideration the source and the destination of the packet (last four columns of the line in trace files e.g. [98:0 0:0 32 0]).

Count received packets only for similar source-destination pair and divide it by total simulation time. That would give you throughput of that particular source-destination connection.

Regarding e2edelay.awk for new trace format - I have not yet designed yet. As soon as it is done, I will upload it here.

@Pdivya - No, there are no patches for WMN for ns-2.29 as far as I know. There are no patches specifically developed for WMN yet. You may get started with the Multiple interface patches provided for WMN in this blog. See the following link:

http://mohittahiliani.blogspot.com/2010/04/revised-adding-multiple-interface.html

Yes, you can modify AODV trace format. For that you need to make modifications in

ns-allineone-2.xx/ns-2.xx/trace/cmu-trace.cc

"format_aodv(Packet *p, int offset)" function.

Hope it helps.

Mohit P. Tahiliani

i am comparing AODV, DSR, and TORA, for avgDelay, packet loss,total dropped packets and throughput. i am using ns2.33 . i have tried with ur all awk script. but i am failed to get the result. plz help me and to write a single program to calculate for 3 routing protocols.that i can calculate those results of those routing protocols easily
thanx and regards

Respected sir, i am going to calculate and compaire of End to end avg delay, packet drop and average throughput of AODV, DSR, and TORA, when i am going to use ur e2edelay.awk and avgthroughput.awk. , i got a finite and comparable result foe AODV and DSR, but i am unable to get any comparable result for TORA with them using the both awk scripts...plz help me.
thanx and regards...
K.L.Hassan

@Ram - It seems this error pops up due to a small typo. Delete the entire $ns node-config line and re-type it once again. Do not directly paste it from some another source.

@Khondekar - TORA does not work correctly by default. It needs to be modified before use. Following link may be useful:

Thanks

@Kalpa - '-t' indicates that the next column (i.e. 3rd) represents time. It is not used in calculating results. It is the 3rd column which is the most important one.

Make sure you are running that script on trace file with new trace format. It wont work for old trace format.

@Priya - That is because you are creating same node more than once. Better to use a "for" loop to create nodes.

@Shrey - I have not yet designed such AWK Scripts yet! Will surely post it once they are designed.

@Khondekar Lutful Hassan - Look at the trace file format for TORA on the following link and modify those 2 AWK Scripts accordingly:

http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats#TORA_Trace_Formats

@Mahfuz - Following link will be useful to you:

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

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

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

@Noor - That occurs when you incorrectly set the "interval_" parameter of CBR. Default value is 0.005 which is very high.

Modify the interval value properly or if you do not know what interval to set - then use "rate_" parameter.

e.g. $cbr set rate_ 200Kb (220Kb is just for example)

@Tohid - AWK Scripts are designed to work with most of the protocols. For your trace file - you can use the AWK Scripts provided on the link below:

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

Hope it helps.

Dear Mohit , i hope that you are ok and fine,well first, i am having a final project about vehicular networks , i am trying to simulate GPSR under NS2 , i did it, and now i am trying to measure the performance of that protocol GPSR , but i couldn't i had some problems , i didn't find the way to read the trace file , i am getting the received packets ("r","RTR") much more from sending packets ("s","RTR") , wish is not logical , i have visited some pages talking about the same problem , wish in it i found that your answering the people in there , so please could you help us to get the correct performance of that protocol ... and what should we do get them ... please guide me...and thank you so much in advance...

NB:the joined files is my scenario_file and my AWK-file ,traffic_file(CBR) .... , that i used to simulate GPSR protocol , NS2.33 , fedora14

@Tohid – NSG2.1 has several options like creating a linear topology (may be vertical or horizontal), a grid, random topology and custom topology. Use any of the options which you require and it will automatically generate a multi-hop topology for you. However, if you want to give separate data rate to every node – you have to do that manually.

@Sneha – The following links will be useful for you:

http://hpds.ee.ncku.edu.tw/~smallko/ns2/Evalvid_in_NS2.htm

http://ns-2.blogspot.in/2007/05/streaming-media-system-for-ns-2.html

@Ammar – The default transmission range in ns-2 is 250m. Whichever nodes fall under this region – suffer from interference.

Scenarios can be created by writing TCL scripts either by hand or by using generators such as NSG (See this blog: http://mohittahiliani.blogspot.in/2009/10/tcl-script-generator.html)

All these parameters can be modeled in TCL Script itself. See ns-2 manual for more detail.

ns-2 has a built-in error model by which you can model error in the simulations.

Different topologies mentioned by you can be created by using NSG tool.
Data rates, transmission frequency and delays are to be configured by the user. You can set as per your requirements.

@Ravi – I hope by this time you might have already completed your project. I guess you might have worked on designing a new routing protocol for MANETs. If not, that’s a decent area to work with for Post Graduate projects.

@Nilam – You can use pdf.awk available here:

http://mohittahiliani.blogspot.in/2009/12/awk-script-for-ns2.html.

It will give you successful packet delivery ratio which I believe is more important parameter.

@Hridya – AWK scripts remain same for most of the wireless TCL scripts unless you modify the format of the trace file. If you are not modifying the format – no need to write a new AWK script as well.

@Ram – Use ./setdest generator provided inside ns-2 to generate mobility with varying speed. See Marc Greis tutorial – Section XI.2 for commands to use “setdest”.

Once you are done with generating mobility scenarios – run your simulation and later, use genthroughput.awk provided on the following link to calculate throughput:

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

@Akram – How to interpret trace file for wireless simulations is provided on the following link:

http://www.cs.binghamton.edu/~kliu/research/ns2code/index.html#trace

@Khoso – I believe that would work!

@Sandy Haff – The trace file format posted by you appears to be a new one. In this format – I don’t see fields corresponding to hand-offs. I would recommend you to ask your query to the author of that wimax patch.

@Boughdiri – Understanding the trace file format is important for designing correct AWK script. I would recommend you to try to understand trace format first and then attempt to write an AWK Script.

Hope it helps.

Mohit P. Tahiliani

@Sharan Noola – Channel idle time can be obtained from the C++ parameter called “channel_idle_time_”. See line #00090 on the following link:

http://rp.lip6.fr/ns-doc/ns226-doc/html/wireless-phy_8h-source.htm

@Shrey – AWK Script for end to end delay is available on the following link:

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

And the one for jitter is available here:

http://mohittahiliani.blogspot.in/2009/12/awk-script-for-ns2.html

@Nir – Use trace2stats.tgz for analyzing these kind of trace files. It is available on the following link:

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

@Gayatri – AWK script named “genthroughput.awk” available on the following link can be used:

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

Hope it helps.

Thanks,

@Doan - Your trace file seems to be bit different than the usual old trace file format. E.g., 4th column usually represents the layers i.e., AGT or RTR or IFQ, etc. But in your trace file - 4th column contains some numbers. Moreover, AGT/RTR/IFQ never appear in your trace file and hence, you are getting those values as 0 when you run the AWK Script.

Generally packet type (e.g., in your case it is DSRCApp) is represented in the 7th column but in your trace file it is represented in 11th or may be 12th column.

There are a couple of things you can try:

1. Find out the exact meaning of each column in your trace file - so that AWK script can be modified accordingly.

2. Suppose you dont get exact meaning of this trace format - in that case change the column numbers in your present AWK script and try running again E.g., $7 must be replaced by $11 or $12 (because in your trace file - packet type is printed either in 11th column or 12th column. I am not able to count properly as it is not structured. You may take a close look and find out whether it is 11th or 12th).

Hope it helps.

Hi sir,

Am using ns 2.34 under fedora os. am doing project in wired cum wireless scenario. i want to patch snoop.cc file with my tcl script.Can u help me sir

Hi sir,

I want to calculate throughput and end to end delay in wired cum wireless environment. can u help me sir.

@Shiny John - snoop.cc is already available in ns-2 by default. You can find it in the following directory:

ns-allinone-2.xx/ns-2.xx/tcp

In your TCL - instead of using LL - use LL/Snoop

I do not have AWK Scripts for wired-cum-wireless scenario. You may try designing yourself with the help of scripts provided on this blog.

Hope it helps.

Regards,
Mohit P. Tahiliani

Good day sir,
I am doing project to compare various tcp variants base on goodput, i need help from your side u have already posted throughput for wireless networks,can u just post awk script for GOODPUT calculation where we are not considering retransmission

Thanking in advance

@Bimal Patel - I have not designed one still for that but doing it would be quite simple. You need to make use of "Sequence number" column and just ignore "Sequence numbers" which appear twice. This is because when a packet is re-transmitted - its sequence number remains same and hence, based on sequence number column in the trace file, we can identify whether the packet is a re-transmitted one or a fresh one.

If it is a re-transmitted packet - don't add its size in your calculations and do not increment the packet counter as well.

Hope it helps.

Regards,
Mohit P. Tahiliani

hello mohit m doing project on wired simulations and i want to calculate end to end delay and throughput from trace file......can u pls help me????
my trace format is as follows:
+ 1.010213 1 2 tcp 40 ------- 1 0.0 2.0 0 0
- 1.010213 1 2 tcp 40 ------- 1 0.0 2.0 0 0
r 1.020427 1 2 tcp 40 ------- 1 0.0 2.0 0 0

@Prajapati Kinjal - You can use the AWK Scripts provided on the following link for the same:

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

See the README file provided on the above link for more details.

Hope it helps.

Regards,
Mohit P. Tahiliani

Thank u sir for proving valuable response but i just want to add that in goodput even we are excluding protocol overhead along with retransmission and what changes we need to make to genthroughput.awk script provided on your blogs for new trace file format.

Thank u

Even the link provided for various awk script
http://www.megaupload.com/?f=0211SAG1 is not working

Thanking in advance

@Bimal Patel - Protocol overhead is already excluded in the AWK Script provided on this blog. You just need to remove the re-transmitted data amount from this AWK Script to make it work for goodput.

Do not refer to any of the megaupload links because megaupload website has stopped working long back. All links on this blog (except the ones provided in my "Replies to Comments") have been modified and the content has been shifted to mediafire.

Follow this link: http://www.mediafire.com/?z1c2cxdt1a31d

hi;
I wrote a tcl script, multicast traffic with a ring topology, I get a prune in the trace file. I don't know how to eliminate these prune from the trace file.
Please if possible did me how to eliminate these prune I want to obtain a trace file that contains no prune.
I work with NS2.34 in CentOs 6.2 wired network. Thank you very much for your help

@Nouran - I recommend you to take a look at mcast.tcl which is provided in the default ns-2 package in the following directory:

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

You can test its working and also check its trace file. Later you can modify it to work for your scenario i.e., ring topology, etc.

Hope it helps.

Mohit P. Tahiliani

Hello, I have a question.

good afternoon sir,i have generated tcptahoe with aodv for 10 nodes cbr traffic using NSG2.O when i am running .tcl files it gives error
Missing required flag -x in: W -t 50.0

Missing required flag -y in: W -t 50.0

Parsing error in event.
Can u suggest the solution for it.
Thanking in advance.

@Mohit i am sorry, but can you expane how i can use it?

@Bimal - You have not generated the traffic correctly. Use FTP when you use TCP or else set the parameters of CBR correctly if you are using it on top of TCP. Try generating again with correct parameters.

@Dmitry - Keep your trace file and AWK script in the same folder. Go in that folder via terminal and give the following command:

awk -f filename.awk filename.tr

Hope it helps.

Regards,
Mohit P. Tahiliani

Thanks for response but i have tried again using NSG2 and this time i have used ftp(start time 1 and stop time 2) and as agent TCP for protocol AODV using 5 nodes random packet size 1500 bytes and 1000*1000
But again it gives same error
Missing required flag -x in: W -t 50.0

Missing required flag -y in: W -t 50.0

Parsing error in event.
Nam is opening even its running but due to error it is not showing anything in out.tr file
Plz help sir
Thanking in advance
Sir it wound be nice if you provide fb account for online assistance help

Sir i want tcl script with aodv as protocol tcptahoe as agent and ftp with 5 mobile wireless node and even i want same with cbr insteat of ftp using NSG.How can set ftp to first node and tcp sink to last node and in case of node setup for movement they are asking destination(x,Y) and speed wht we need to write in case of speed


Thanking in advance

@Bimal - I would recommend you to go through Section IX and Section XI of "Marc Greis Tutorial" first and then generate the TCL Scripts by using NSG.

Hope it helps.

Regards,
Mohit P. Tahiliani

Thanks for advice. I had gone through section IX and section XI and tried but still it shows the same error any ways i have already done using cbrgen.tcl file available in ns2 there i have tried with tcp/ftp and udp/cbr and even node movement using setdest and it is sucessful but since i am working on Tcp variants how can i generate other tcp variants(tahoe,reno,new reno,vegas) using cbrgen.tcl


Thanking in advance for valuable support

@Bimal - If you have already generated TCP/FTP using cbrgen.tcl then you just need to do "Find and Replace".

For TCP Reno - replace TCP in the generated file by "TCP/Reno". No need to change TCPSink.

For TCP Newreno - replace TCP in the generated file by "TCP/Newreno". No need to change TCPSink.

For TCP Sack - replace TCP in the generated file by "TCP/Sack1" and TCPSink by "TCPSink/Sack1"

Similarly, repeat the same for all other TCP variants whichever you wish to simulate. Thats it!

Hope it helps.

Regards,
Mohit P. Tahiliani

thanks, but everytime is (throughput - 0 ) Is it working for WiMAAX?

@Dmitry - Which throughput file are you using? Please use genthroughput.awk available on the following link:

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

Make sure your packet size in TCL is more than 500 bytes. If it is not, replace the same in AWK Script also. This AWK script will work for old trace format. I am not sure WiMAX TCL Scripts use which trace format.

Hope it helps.

Regards,
Mohit P. Tahiliani

i have got a result that s: 5555556, r:480678, r/s Ratio:0.0865, f:0.
What does it mean?
How many packets were droped?

Thanks
Dima

@Dmitry - r/s Ratio means "received / sent Ratio". Multiply it with 100 to convert it to percentage. In your case 0.0865 * 100 = 8.65%. It means 8.65% of the packets were delivered successfully and remaining were dropped.

Hope it helps.

i need to trace the distance in the terminal using two ray propogation model can u help me sir its urgent

Hello sir,

I just want to count total number of packet send and recieve for 10 and 20 nodes scenario for normal and blackhole behavior for AODV

Can u suggest the awk script for it new trace format

Hi Mohit

I am new in NS2 and I need your help please. I would like to add 4 routing protocols (FLOODING, DIRECT DIFFUSION, ANT, GOSSIPING ) in my NS2.35 folder and I want them to run with a TCL code that we have built with a some colleagues. Please tell what should I do?

hi mohit
how I add any column in the trace AODV ?
thank you for your help.

Hello , i want to analyse the performance of the dccp protocol by comparing it with tcp and tfrc protocols with having one delay graph and throughput graph. But i didn't know how programing with tcl and awk may you help me please ? to have the tcl code and the graphs . :(
Thanks

Hi Mohit,
i am working on ns2.28 in ubuntu10.04 with virtualbox.
my project is analyzing energy efficient protocol in MANET. after adding span protocol in ns2.28, any other example file cannot run.
how can i do? please help me . i really need your help.

hello am lecturer in kau university am working in adhoc networks now i have a problem with dymo after the execution the dymo script in the ip trace -it filed is coming as undefined ,its not specify the packet type as either cbr or dymo.

hi mohit sir,
i wanna get throughput of 10,20,30,40,and 50 nodes for aodv,dsdv and dsr.
i m getting this error while commanding xgraph aodv.xgr
Error in file `aodv.xgr' at line 1:

Problems found with input data.
i have read your answers to the ns2 users who had the same errors but i m not exactly getting how to modify that throughput.awk file and i m not able to overcome the error..so kindly pls help me sir...
thank u very much sir..

hi, can you plz give instructions to write the awk script for energy occupied in power aware routing of AODV and DSR...

I am doing something about wireless Lan handover simulation but yet i donno where to find the example TCL file. your known whr can get it?

after i typr the coding awk -f packetdeliveryfaction.awk wireless_mitf.tr > out.xgr
i get cbr s:4101 r:4079, r/s Ratio:0.9946, f:0 in the xgr file.
and after that i type xgraph out.xgr . the error shows Error in file `out.xgr' at line 1:
Unknown line type
Problems found with input data.

why there are no xgraph drawn?

Sir while running aodv under 10 nodes i am getting throughput 314 and when i apply blackhole under aodv 10nodes wity one blackhole it is reduced to 234.Is is valid to get throughput above 100 what is the reason for getting throughput above 100

Hello sir,

i am comparing aodv and aomdv with varying node speed but i am getting result aodv outperforming aomdv .what is the problem??pls help me i am using setdest to vary the speed of the node. i have varied the speed 1,2,3,4,5 m/s .

hello sir,
i am trying tora protocol, do you have any awk scripts related to tora protocol, if you have pls upload i need it for my project

I am a final year student doing Btech project on "Artificial Immune System for Intrusion Detection In MANET".We are using ns2 as a network simulator. We obtained the flood.tcl script of flooding attack and got the trace file.But we are unable to detect flooding by observing trace file (flood.tr).Is there any way to detect that there is flooding.Can you help us or suggest some way to detect flooding attack.

sir,
will you plz help me by giving information about new trace file format,because i am working on zig-bee energy model,so it is necessary to run the program in new trace file format.plz help me out.
ayan kumar dey

In my project i want to find the output of delay(End TO End),throughput,packet delivery ratio.I run my program on old trace file format,but it fails everytime.Plz help me out by giving new trace file for those above mentioned program.I am doing my program in zig-bee for energy model diagram.
ayan kumar dey

hello sir
in my project i am finding value of energy consumption vs Bit error rate..every time i am changing ber from tcl file n then run tcl file using ns filename.tcl then using awk file to calculate energy consumption..is it correct procedure? Bcoz i hav buy project from one institute the value obtain from awk file are not match with thier xgr file.plz suggest me something..

@Anvika - Yes, the procedure that you are following is correct.

Just ensure that the AWK script which you are using is correct.

Hope it helps.

Regards,
Mohit P. Tahiliani

please upload the awk files to calculate pdr END2END DELAY for new trace format

sir,
when i was running tcl file,i got following error.
suggest me the solution for error

num_nodes is set 2
invalid command name "-llType"
while executing
"-llType $val(ll) \

Thank you..

@Unknown - Try removing extra space characters before -llType.

Hope it helps.

Mohit P. Tahiliani

Sir is ns2 source code for clustering in aodv is available

Sachin

dear Sir while i was going through your awk code for calculating throughput i wasn't able to understand this part of the code
"hdr_size = pkt_size % 512
pkt_size -= hdr_size

recvdSize += pkt_size
} "
please sir help us in this regard
thanks inadvance

@Sachin - No, because AODV is not a hierarchical protocol.

@Shravan - That code removes the header from the calculation and considers only the payload. 512 is considered as an average packet size. If you are using a different packet size in your simulations, change it accordingly.

Hope it helps.
