Hello Sir,
totalpacket sent awk script gives output as 0 always.

What is the problem in that. I am using totalpacketsent.awk script for that and I am using it on new trace file format.
Thanking you.

goodmorning sir im doing my project on performance evaluation of TCP variants(RENO,VEGAS,NJplus)over AODV,DSDV..plz help me i hve install ns2.34 on red hat but its tcl file is not working,im giving the command ns test.tcl its not working plz help me ........can it is possible to do in REDHAT

@Harpreet - Trace format of wired-cum-wireless is different since part of trace appears in wired format and rest in wireless. Hence it is better to modify the pdf.awk accordingly.

@Ram - Check for some typos in your script.

@Divs - Install LEACH patch on ns-2.27 and use the sample TCL Scripts therein for clustering.

@Riaz - You can get most of the information about IPv6 simulation in ns-2 on the following link:

http://brc.nitk.ac.in/?IPv6_Mobility-NS2

@Hello - See the following link:

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

@Nishidh - totalpacketsent is designed for a specific topology and will not work on other topologies. Make changes in it as per your topology and re-run. Moreover column numbers in new trace format are different than the ones in old trace format. So you need to use the new column numbers in the script.

@Sourabh - Go in

ns-allinone-2.34/ns-2.34 and give the following command

make install

Hope it helps.

Mohit P. Tahiliani

Hello Sir,

I'm looking for an example oh AWK script to determinate node energy in NS2. I see that you have published lot of example on megaupload , but us you know MegaUpload is now blocked. So can you sir re Upload these files and give me the new link ?
Thank you Sir in advance, and I'm waiting for your reply.

sir .i have the m-parameters .awk file for cbr traffic.how can i use this same file for tcp traffic .please tell me sir as soon as possible.i have some error like division by zero aatempted.how can i solve this problem..plz reply me fast..

Hi mohit

i am trying to find out link utilization between two nodes, in wirless , both r static nodes , whereas 0 is receving 2 is sending and it back off is resetting , i want to see how much impact it is putting on link

need help

BEGIN {
recvdSize = 0
startTime = 400
stopTime = 0
}

{
event = $1
time = $2
node_source = $3
node_des = $4
pkt_size = $8
level = $4

# Store start time
if (level == "AGT" && event == "s" && node_source == 2) {
if (time < startTime) {
startTime = time
}
}

# 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)
}

hi Mohit


this is used for average what abut if we interested on single link. one to one,

i have done that but i am getting same results

if (level == "AGT" && node_id = "_2_" && type == "cbr" && event == "s" && pkt_size >= 512 )

hi Mohit,
I am trying to make a new type of node for my project work. options are like can abstract from class Node in ns2 or class MobileNode. This node will only have mobility and no other method associated. The type of mobility to be given can be changed later,i.e. mobility model can be varied. It will be a WSN scenario and i am using mannasim for that. To start with,i am using only one cluster with a cluster head. The nodes in cluster should be able to detect the movement of the new type of node created and report its instantaneous location to cluster head.
My first problem is obviously how to create this new node? And then, how to sense its motion?
Regards.

Hi Mohit,
I have the following scenario

wireless network consists of 1 access point and 9 nodes. all nodes communicates with each other through access point.

In this network i need to find channel busy time=medium busy time/cycle time

In ns2 i don't know to find channel busy time, can you please provide awk script to find channel busy time for both old and new trace file format. Kindly help me

Thank You

Sir, actually routing overhead = routing packets/ total packets send. how to find routing overhead in a manet in ns2. or routing packets.

Sir, I have to find routing overhead in manet in ns2. I know routing overhead = routing packets/total packets. I am able to find total packets but not able to get routing packets. Kindly help in finding routing packets.

Hello sir
My scenario used wireless nodes and UDP and AODV protocol( NS2.29).
I want to calculate throughput and delay but I have more problem , for calculate throughput, which formula is true? ( numreceivepacket / numsend packet ) and for calculate delay, should I minus send time from receive time one packet in the same layer? (for example send and receive time in MAC layer). and next problem is that in my tarce file I don't have send time in MAC and AGT layers and also I don't have receive time in RTR layer.

If necessary for clarification, I send my trace file.

Please help me , thanks ...

@Atef - All the files which were earlier on megaupload have been shifted to mediafire. Check out the following link:

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

@Shalu - Replace "cbr" by "tcp" in the AWK Scripts.

@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.

@Sukhi - I believe most of the features of your new node would be similar to the MobileNode and hence I recommend you to inherit your new Node from MobileNode class. You can refer to NRLSensorsim patch for NS-2 to know more details on how to create a new node.

@Sharan - Sorry, havent worked with that yet. Will post details if found.

@Shakeel - You can download the AWK Scripts to calculate Normalized Routing Load from the following link:

@Shrey - AWK Scripts on the following link will help you to calculate throughput and end-to-end delay. For handover latency you will have make few modifications in e2edelay.awk based on the "Binding Update" messages which are printed in the trace file.

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

@Sandy - The formula to calculate average throughput is (total bytes received / total traffic time). AWK Scripts for throughput and delay are provided on the link given below:

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

Hope it helps.

Hi Mohit,

I am trying to run SCTP-CMT simulations in NS2 as given in the sctp.README of the ns2 module. Once the trace file is generate, I tried to use the throughput awk script to calculate the throughput. However, I dont get the required output:

It gives 0:


awk -f gen_tput.awk all.tr
Average Throughput[kbps] = -0.00 StartTime=400.00 StopTime=0.00

Are you aware how to obtain the throughput for sctp-cmt simulations given in the sctp.README of ns2 ?

Shreyas

Dear mohit,
How to change the transmission range of a mobile node dynamically?

@Geetica – Following link explains one way to do it:

http://www.linuxquestions.org/questions/linux-newbie-8/insertion-steps-of-vbr-into-ns2-34-a-868010/

and it can also be done as follows:

set vbr [new Application/Traffic/Exponential]
$vbr set packetSize_ 280
$vbr set rate_ 300k
$vbr set burst_time_ 100ms
$vbr set idle_time_ 50ms
$vbr attach-agent $udp

@N – You may try using the AWK script provided on the following link:

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

@Mani – One such code is given and explained on the following link:

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

@Shreyas – There are several factors to be considered while using the AWK script for throughput given here. Make sure you are using this AWK Script on wireless trace file. Another thing to be considered is the packet size which is set in your TCL script. Replace 512 by the packet size that you have used in your TCL script.

@S M Joshi – I doubt whether that can be done because generally we change the transmission range by using threshold.cc. But it is not dynamic.

Hope it helps.

Hi Mohit Sir,
I have installed ns2-2.34 on ubuntu 11.04. It was installed successfuly and generating nam files also. But i am unable to access trace files to plot xgraph.
when i am giving
awk -f filename.awk filename.tr
ex: awk -f wired_end2end_delay 1.tr
I am getting following error

awk: wired_end2end_delay.awk: line 69: illegal reference to array rcvdTimes

can you please tell what will be the problem and solution for it. By the way i checked the source files running with ns2-2.30 version, which was installed on ubuntu 10.10.
Hope you will solve my problem please.

2- can you explan for me whats mean of HELLO message?)
best wishes
Sirwan

@Nir - To analyze the trace files which you have posted, use trace2stats available on the following link (See README for more details on commands):

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

@Naga Lakshmi - There seems to be an error in the way you are using an array to store received time of each packet. Look into it carefully and re-run again.

@Abbouur - The following link has exactly what you want. Comparison of AODV, DSDV and DSR while using Random Waypoint Mobility Model:

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

@MuthuMeenakshi - Use the one given on the following link:

http://mohit.ueuo.com/AWK_Scripts/totalpacketsreceived.awk

It is designed for only few nodes. Modify it to calculate for all nodes in the network.

@Najma - Make sure you are looking at the correct trace file. Because if there are 10 nodes - numbering is generally from 0 to 9.

@Sirwan - The following link is a good reference to get started with security related stuff in ns-2:

http://elmurod.net/index.php/category/network-simulator-ns2/

HELLO messages are like "keep alive" messages which are used to find out whether the neighboring nodes are active or not (or within the range or not), etc.

Hope it helps.

hi sir,
can u send me a awk code to calculate throughput and dealay for wired cum wireless networks.

@Shiny John - Sorry Shiny, I havent designed one yet. I will upload it on this blog as soon as I do it.

Meanwhile, you can try to design your own AWK script for adhoc use.

hi sir,i attended workshop at surathkal.N.vanaja,i have to implement a project in ns2.sir,where to write code for dos attack

hi sir

@Vanaja - It depends which kind of DoS attack you want create in ns-2. Depending on that I can suggest a few files where you need to make changes. For e.g., if want to create DoS using SYN - then you need to make changes in tcp.cc, tcp.h in ns-allinone-2.xx/ns-2.xx/tcp directory.

Hope it helps.

Dear Mohit P. Tahiliani,

kindly can helpe for prgoraming by C++ for RC5 cipher algorithm?

@Sirwan - Sorry, I have not worked with it! Following link might be of some help to you:

hello sir, i have simulated adov rp with 20 nodes and i want to calculate throughhput for it.. i have used genthroughput.awk provided in the blog, and my doubt is..

shud i calculate throughput for every node separately and average them for average throughput??? in the script provided here node_id is nt used.. what does it mean??

kindly help me sir n thanks in advance

@Raviteja - genthroughput.awk calculates average throughput itself. It does not calculate the throughput of every flow. genthroughput.awk would serve your purpose.

Hope it helps.

Mohit P. Tahiliani

hello mohit sir
i harshil patel
sir i make wireless script using aodv. but when i change protocol dsr insted of aodv in script then error is generated like "segmentation fault (core dumped) so please help me sir
thank you

Hi Sir,

any script for goodput calculation?

Thanks,
Abhishek

@Harshil - Whenever you use DSR as the routing protocol - you must use CMUPriQueue as the interface queue i.e.

set val(ifq) CMUPriQueue

must be used.

This is because DSR's ns-2 code was contributed by CMU and they made a specific queue called "CMUPriQueue" which has to be used while running DSR.

@Abhishek - Glad to know you still visit this blog!

I guess you want AWK Script of goodput for wired networks, right? In that case, you can use the same AWK Script which we used during your project. Goodput needs two things: (1) Header overhead must not be calculated and (2) Re-transmitted packets must not be considered for calculation.

AWK Script which we used for your project eliminates header overhead in the calculation - thus satisfies (1) which I mentioned above. However, it does not eliminate re-transmitted packets. Just make this change and you will get a AWK script that calculates goodput. Use sequence number field in trace file to eliminate re-transmitted packets from the calculation.

Hope it helps.

Mohit P. Tahiliani

Dear sir,
I have followed your blog. Still I am totally confused regarding the trace file calculation.
Simply I need to calculate the no. of sent, recv, and dropped packets from tr file. But I am getting recv packets more than sent. so how it is possible ? pls help me with simple ex. I am sending my tr files. I am not putting right formula to calc only data packets.

from both the files I need to calc sent recv and dropped packets separately. please help me sir.

Hello Sir,

Sir where can i get a handover latency awk script?

@Balado - At the moment, I do not have an AWK script to do that, probably because I haven't worked on that area yet.

HELLO SIR,

I am also getting an error during opening my code like
: ns command not found
Please help me out from this so i can go for my further process.

Regards
Prami

@Prami - That error means ns-2 is not installed in your machine.

If you are using Ubuntu, the simplest way to do this would be to give the following command:

sudo apt-get install ns2

Hope it helps.

Hello, Mohit sir!

Sir, I am getting a problem in running example script also in ns-allinone-2.35. Actually I am using Cygwin and ns-2.35 on window 8.
After installing (./install) ns2.35 in Cygwin, it shows this line "gcc4 package is not present on your system"

Should I have to install a different version of Network Simulator2 because I want to work on Cygwin?
Else suggest me how to work on VMWare workstation for running NS2 scripts

@Prami - That means your gcc is not compatible with the version of ns-2 that you are trying to install.

I would recommend you to install Ubuntu in a Virtual machine and then give it a try.

Hope it helps.

Mohit P. Tahiliani

Hey Mohit
This Vishvas From Pune
can i get new awk file to analysis Trace file, which generated by NS2.34

Respected Sir
NS2 is working fine but i have vbr_traffic.cc and it is placed in tools folder. changes made in makefile.in. when i am executing ./configure in control panel it gives an error, i.e

configure: error: Installation of tcl seems incomplete or can't be found automatically.
Please correct the problem by telling configure where tcl is
using the argument --with-tcl=/path/to/package
(perhaps after installing it),
or the package is not required, disable it with --with-tcl=no.

how to solve this problem please help me sir

Hi Mohit,

My project is about detecting malicious node on MANET using NS2. Is there a way that i can use traceroute command MANET to show which route the packets took to the destination? I think this way will help show where the packets were dropped, i.e. malicious node. I have used awk script that you have provided but i need more evidence.

I need assistance urgently as my submission date is very close

Thanks

Hans
