Hi mohit,
i have the tcl script for wormhole attack in AODV protocol, but i have some difficulty for wormhole attack in DSR protocol. If u have a TCL script for wormhole attack in DSR then give me pls.
thanx ..

Hi sir;
thanks for ur help in advance; I am new in ns2 and I want to know how I can calculate the number of routes used to transmit traffic between source and destination.

Thank you

Thank you

Hi sir;
I am new in ns2, plz can you explain for me why you put in your script genthroughput.awk :
1. startTime = 400
2. && pkt_size >= 512
3. # Rip off the header

hdr_size = pkt_size % 512

pkt_size -= hdr_size
In my trace file, I have pkt_size=0 for event=="s" and level=="AGT" for ftp traffic
Thanks in advance

Please help me in rectifying it.

Hi Mohit ,


can we implement 6LowPAN over 802.15.4 in ns-2 ? can you suggest any simulation tool for this implementation ?

Hi Mohit .

can we implement 6LowPAN in ns-2 over 802.15.4? if no.. then can you suggest me any appropriate tool to simulate it ?

Hello Mohit
I am currently working on WMN, I used the AWK script for throughput/delay and its working fine for the entire network, is it possible to modify the script such that one will get throughput for an individual node or can one calculate throughput for just one node

Thank you for this Mohit :)
I want to know how I can retrieve the packets loss and signal signal strength from a file .tr ?

Thank you
S.K

sir, how to save the output of a awk file into another file?

hi mohit sir,

please guide..
i want to estimate the network lifetime in an aodv network and compare them for varying number of wireless nodes and the varying values of initial energy. how can i do that? also the results are to be plotted using Xgraph ..

Dear Sir,
when i use trace file for new trace and got like -29.Can you help me look what did I do wrong?IS it ok if I'd like to send my related file to you?

Hello Mohit Sir,
I am gokul n i am doing my final year B.tech project on csma protocol with power backoff. In my project i have to compare the already existing the temporal backoff which mac 802.11 protocol uses for contention resolution and the new csma protocol with spatial(power) backoff. Firstly, I want to know which file to select to execute the temporal backoff in mac 802.11 protocol. Secondly, I want to know whether there is already a code in ns-2 to implement csma protocol with power backoff. Please help me I'm new to ns-2 and I need you help badly.

Regards,
Gokul

Hi Sir,
I am using ns2 and I'm trying to execute a script.awk for the protocol AODV in order to calcul the throughput,energy and end to end delay.is there any script.awk for these parameters and for the protocol AODV because the trace file is not like the other.
thx a lot :)

Hello Mohit Sir,i am Darmin from Malaysia.

}
}

# Update total received packets' size and store packets arrival time
if (level == "AGT" && event == "r" && node_des == 0 ) {
if (time > stopTime) {
stopTime = time
}
# Rip off the header
hdr_size = pkt_size % 512
pkt_size -= hdr_size
# Store received packet's size
recvdSize += pkt_size
}
}

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

Dear sir,

Please Send me the AWK script to find out energy level of each node at each instance of time.

Thanks in Advance.

I working on wireless network , Now I want calculate energy efficiency for sleep nodes in protocols like SMAC kindly help me. mahaveerjj@rediffmail.com

@Meenakshi - Number of packet sent between two nodes can be counted by using $1, $3, $4 and $7 information available in the trace file. Modify the available AWK scripts accordingly.

@Naishita - For old trace format, only the column numbers differ. The rest of the logic of an AWK script remains the same. So change the column numbers appropriately.

@Suga - It is not recommended to create a sensor node with 802.11. Instead you can check out the sample TCL Scripts provided for 802.15.4 in NS-2 package in the following directory:
ns-allinone-2.xx/ns-2.xx/tcl/ex/wpan

@Alain - There are many factors that affect the throughput, e.g. Switch off RTS/CTS and you will see a drastic increase in the network throughput. Moreover, achieving 100% throughput in wireless networks is still an open research problem!

@Spyware - You need to modify the existing AWK Scripts based on the instructions given on the following link:

http://mohittahiliani.blogspot.in/2010/08/xgraph-and-awk-scripts-in-ns-2_06.html

@Honey - trace2stats available from the following link will be useful to you:

http://perso.citi.insa-lyon.fr/mfiore/research.html

@Zara (Virgo) - The default output is in bytes/second and hence we convert it to Kbps. NS-2.33-AOMDV-Multiple-Interface patch seems to work fine. Please ensure you have followed the steps correctly.

@Theking - energy.awk provided on the following link may be useful to you. However, make sure you modify it according to your requirements.

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

@Lotus - FEC is by default implemented in the ns-2 package. You can also find some details related to same on the following link:

http://ns-2.blogspot.in/2007/05/hacks-adding-forward-error-correction.html

Hope it helps.

Regards,
Mohit P. Tahiliani

@Amol - Sorry, havent worked with that. Will post the details if found.

@Haji - The number of routes between a source and destination can be found out by printing the routing table of the routing protocol being used.

startTime is initialized to 400 so that the first time when if (time < startTime) is executed - it turns out to be true and simulation start time can be captured. It is required for calculating throughput.

pkt_size > 512 is because in my TCL Script I have set data packet size as 500 bytes. Modify it accordingly based on what packet size you give in the TCL script.

The header is removed because the it is not useful for the application.

@VishwanathMS - The xgraph file must not contain any additional data apart from the two columns which form X and Y axis of the graph. Read the following blog:

http://mohittahiliani.blogspot.in/2010/08/xgraph-and-awk-scripts-in-ns-2_06.html

@Phocus Array - 802.15.4 is available in the default package of ns-2. Find the sample TCL Scripts in the following directory:

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

@Shaveta- The sample TCL script is available in the following directory:

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

@Mintu Singh - Better to use the TCL Script provided on the following link while working with MANETs:

140.116.164.80/~smallko/ns2/adhoc_routing.htm

@Nombuso - Throughput can be calculated for the entire network or for a particular link. For both, the logic remains the same. Only the fields in the trace file must be appropriately used.

@Mils - "D" in the first column of the trace file indicates a packet loss. Received signal strength cannot be calculated from the trace file. It must be printed from the C++ file.

@Tushar - Give the following command:

awk -f filename.awk filename.tr > filename.txt

@Niteshagrawal - energy.awk available on the following link may be useful to you. However, make necessary modifications as per your requirements.

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

@Pare - Didnt get your question? Can you make it more clear please!

@Gokul - All files related to 802.11 are available in the
ns-allinone-2.xx/ns-2.xx/mac directory.

The syntax of executing all 802.11 types can be obtained from

ns-allinone-2.xx/ns-2.xx/tcl/lib/ns-default.tcl

The default values are set in this file.

@Realiste1988 - AWK Scripts provided in this blog will work fine for AODV.

@Darmin - Sorry, havent worked with that. Will post relevant details if found.

@Passion of the Christ - energy.awk available on the following link may be useful but modify it according to your requirements.

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

@Khoso - Link utilization is nothing but the throughput. To calculate that for two nodes, modify the if condition to include sending and receiving node numbers, "s" and "r" as $1, "AGT" and "RTR" as layers and packet type = cbr OR tcp whichever you have used in the TCL Script.

@Dhaval - Create an AWK Script based on the guidelines given on the following link:

http://mohittahiliani.blogspot.in/2010/08/xgraph-and-awk-scripts-in-ns-2_06.html

@Mahaveerjj - energy.awk available on the following link may be useful but modify it according to your requirements.

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

Hi, I'm new to ns2, i'm using your throughtput_newtrace, may i know what are these parameters for
recvdSize = 0
startTime = 400
stopTime = 0

and why the starttime is set to 400?

I want to calculate the throughtput for the whole 802.11 network that i setup, is it correct to use this awk script?

this is my email address justme7345@gmail.com

Can you please drop me a email. I've got a ns2 question that i would like to ask but afraid its to long to type it out here.

Thank you.

Looking forward to your reply.

@Jan - The justification for setting starttime = 400 is given in my previous comment (just above your comment).

Yes it is alright to use this AWK Script for 802.11 networks.

Hope it helps.

Regards,
Mohit P. Tahiliani

Hi,

I use the throughput_newtrace to calculate the throughput but i realize it only works for FTP traffic. I am simulating CBR traffic.

How can i modified the awk script to calculate CBR traffic.
And can it calculate both, as i want to calculate the throughtput of the network that sends both type of traffic.

Please reply ASAP, urgent.

Thank you so much.
justme7345@gmail.com

@Jan - throughput_newtrace works well with both FTP as well as CBR because there is no such condition mentioned in the script that differentiates both type of traffic. May be you are not getting result because of different packet size used in the TCL Script. Replace 512 in throughput_newtrace by the packet size which you have used in the TCL Script.

Hope it helps.

Regards,
Mohit P. Tahiliani

plz tell me how to calculate throughput of tcp hybla and various flavors in heterogeneous enviornment?

@Nir - genthroughput.awk available in this blog can be used to calculate throughput for all flavors of TCP.

Hope it helps.

@Shiny John - This AWK Script is not correct because it is designed with respect to old trace format which is different than the one used in wired networks.

You need to design a new AWK Script for such a scenario.

Hope it helps.

hi all ..
I have the task of simulating the energy in the battery to wirelles sensor network using NS-2 ..
I do not know his awk script
please help me ..
thank you ..

I'm sorry my english is very bad

hi this is raj and i want a script of energy consumption ,routing protocol used aodv and how can i draw xgraph between two parameter.
my gmail id is titfortat.raj@gmail.com
so if you have script so please send me on my email address

@Bambang - You can find the sample TCL script for energy consumption in the default package of ns-2 in the following directory:

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

Name of the TCL Script is: wireless-newnode-energy.tcl

AWK Script for the same can be downloaded from the following link:

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

Name of the AWK Script is "energy.awk" (Note: You will have to modify it for your use).

@Paritosh - Same answer applies to you as well !!!

Hope it helps.

Mohit P. Tahiliani

b = $10;

c = $11;

d = $12;

energy = $14;

for(seqno = 0; seqno < 68; seqno++) {

if((node_id = "_5_" && action == "r" && layer == "AGT" && type == "cbr" && size >= 1000) || (node_id = "_6_" && action == "r" && layer == "AGT" && type == "cbr" && size >= 1000)) {

count++;

}

}

}

END {
printf("%d\n",count);

Hi,
Can I get the awk script for energy consumption

Hello sir,
I am doing my project in ns 2.34, so can you please mail me the awk script for calculating the average residual energy of the nodes in the network. I tried on my own but didn't get correct results, i request you to mail, my mail-id:-
shrutibhavi@gmail.com

hello sir
I m working on ns2.35 ubuntu 12.04
when i try to use awk script for genthroughput, instant jitter, e2e delay using command
awk -f filename.awk ns.trc >aodv.xg
then it always show that
awk: cannot open genthroughput.awk(No such file or directory)
bt it works fine for pdf (pdf and other scripts are in the same folder)
plz help me sir
thanx

plzzzzz sir reply as soon as possible thx

@Angel - This means that genthroughput.awk is not available in the same folder where you are giving the awk command.

@Shruti Bhavi, Surbhi and Ayan Dey - You can try getting the same by using the Automated Post Processing (APP) Tool which we have designed recently. Following is the link: http://mohittahiliani.blogspot.in/2014/10/automated-post-processing-app-tool-for.html

hello sir, im trying to find tcl script for HybridMAC protocol that is needed to run in wireless Ad hoc networks environment by using ns2..do u have any idea where i can find suitable script?plz help me...how can i change the script according to my parameters?

hello Mohit i use e2edelay awk but i get output as-
devki@ubuntu:~/Desktop/raushan$ awk -f e2edelay.awk out.tr


Average End-to-End Delay = -nan ms

what is going thsi please help me

Hello Sir

please provide me FSR source code in ns2 and how to draw xgraph for more than one xg files on a single graph to compare the values for different protocol.

please tell me how to do that

Regards

@Richa Goyal - The FSR patch for ns-2 can be downloaded from the following link:

http://fsr-routing.sourceforge.net/

Give the following command to plot multiple ".xg" files using xgraph:

xgraph file_1.xg file_2.xg . . . file_n.xg

Hope it helps.

Regards,
Mohit P. Tahiliani

@Kuljit - I have not worked on HybridMAC and moreover, haven't come across any such code as well. So could not assist you much on this!

@Devaki - Check within the AWK Script whether "if" conditions match your requirements or not. If not, please change them as you need and try again.

Hope it helps.

Regards,
Mohit P. Tahiliani

hi...my project contain comparison of aodv and NCMR protocol(for unicast and multicast network) in terms of four parameters like energr,sdr,packet loss,end to end delay...will u please send me tcl script and c++ code for aodv unicast & multicast which giving parametrs with respective to BER

@Anvika - AODV is just an unicast protocol. Multicast AODV (MAODV) is another variant of AODV which is a multicast protocol.

First you need to patch MAODV in your machine and then carry on with the project. Sample TCL files for AODV are available in the default package of ns-2 and those of MAODV are available in the patch itself.

Hope it helps.
