Hii,
After making changes in files in file from the link http://all-time-ns-2.blogspot.in/2010/10/adding-new-routing-protocol-in-ns-2.html, I get an error message while executing make clean command
"nidhi@nidhi-Inspiron-3542:~/ns-allinone-2.35/ns-2.35$ make clean
Makefile:337: *** commands commence before first target.  Stop."
what should I do for resolving the problem?
I am attaching Makefile file along with this mail. Please do the needful. Also in which file I have to make changes, in Makefile or in Makefile.in.
In the attached file, I added code
"draodv/draodv_logs.o draodv/draodv.o \
    draodv/draodv_rtable.o draodv/draodv_rqueue.o \"
 in line number 278 & 279.

Thank you

[knudfl]

@Nidhi Chhajed ,   Hi.

Makefile.in :  In a section like "OBJ_CC", the lines / objects.o are entered this way :
<TAB>folder/obj-a.o folder/obj-a.o \
<TAB>folder/obj-c.o folder/obj-c.o \

No spaces instead of the <TAB>, no <linefeed> between lines are allowed.
No <TAB> followed by empty space is allowed.
And no <space> after a backslash ( \ ) is allowed.

Your lines 278 - 281 ( with an issue ?) :
<TAB>draodv/draodv_logs.o draodv/draodv.o \
<TAB>draodv/draodv_rtable.o draodv/draodv_rqueue.o \
<TAB>
<TAB>aomdv/aomdv_logs.o aomdv/aomdv.o \
( And there is a "space issue" with lines 304 - 311 )

Must be :
<TAB>draodv/draodv_logs.o draodv/draodv.o \
<TAB>draodv/draodv_rtable.o draodv/draodv_rqueue.o \
<TAB>aomdv/aomdv_logs.o aomdv/aomdv.o \

.....  The edited Makefile.in is attached as Makefile.in-edited.txt .

*********************************************************************************
Your question is actually about the old existing Makefile, not the Makefile.in .

HOWTO 'make clean' :
Run ./install in the top directory, ns-allinone-2.35, and a new Makefile is created in ns-2.35/.
Then you can do $ cd ns-2.35/ && make clean
.... And you can go back to the top directory, ns-allinone-2.35, and run ./install
 
*********************************************************************************

[knudfl]

@Nidhi Chhajed  : 

Correction :  You may have to delete the faulty Makefile before running ./install

-

[Nidhi Chhajed]

thank you so much sir for your kind help. I have removed space from Makefile and the file become error free.

Hello..

I have sort out the problem but while validating ns2 some validations failed. Is it cause some problem in running tcl files.

Problem :

"

"

[knudfl]

@Nidhi Chhajed ,  Hi.

About validate : Don't worry about the failed tests.
The validate result often gets worse when a new protocol is added.
But as long as you can run your special "draodv" simulations, it doesn't matter.
.... Anyway, nothing you can do to improve validate results.

And :  A 64bits OS will usually provide an inadequate result with any default ns2 version.
( Your OS is unknown, I think.)

-

[Nidhi Chhajed]

Hello,
Sorry for not mentioning OS version before. I am using ubuntu 14.04 64 bit OS.

After executing tcl file, I got an error message

"
nidhi@nidhi-Inspiron-3542:~/Desktop/ns2_programs$ ns test_file.tcl
num_nodes is set 2
INITIALIZE THE LIST xListHead
can't read "udp0": no such variable
    while executing
"$cbr0 attach-agent $udp0"
    (file "test_file.tcl" line 84)

"

Also the network animator is not displaying. What to do?

[knudfl]

@Nidhi Chhajed ,  Hi.

You cannot expect any answers about your unknown protocol (draodv?).
Or your unknown file = "test_file.tcl".

Nam :  The Ubuntu 'nam' packages have been useless since ~Feb 2014.
( There is a bug report.)

A nam package that works :  nam_1.15-10-ubuntu14_amd64.deb
https://drive.google.com/file/d/0B7S255p3kFXNdmxzSmRzaVRWb28/view?usp=sharing

-

[Nidhi Chhajed]

I have installed package attached with this mail. Is there any issue with this package.

Also I am not using new protocol in test_file.tcl. It is a simple file of 2 wireless node, which is also attached along this mail. What should I do to resolve the problem.

[Nidhi Chhajed]

Dear sir,

I got the following error while opening file in nam
"You are using the tracefile format older than 1.0a5
which will not allow you to run namgraph"

Is this error come because of using older version of NSG2. Can I upgrade NSG2?

[knudfl]

@Nidhi Chhajed ,   Hi.

No reason to attach a 4MB package, when you can just tell the file name, nam_1.15-10_i386.deb
If you really have a 64bits OS, then .i386 is the wrong package choice.
Right is nam_1.15-10-ubuntu14_amd64.deb .

-

[Nidhi Chhajed]

Hello sir,
Yes I have 64 bit OS. So I have to reinstall the nam after uninstalling 32 bit nam??

[knudfl]

@Nidhi Chhajed.

You have literally no nam file to run, if it's the test_file.nam from running test_file.tcl.

A nam animation file must be more than the "head lines".

Please try another NSG2 generated example : aodv-routing.table.tcl  (Attached.)
.. And read the out.nam file : The first 29 lines are the specs / headlines !

-

[knudfl]

? »» So I have to reinstall the nam after uninstalling 32 bit nam «« ?

Yes. If you want nam, you will have to install 'nam'.

-

[Nidhi Chhajed]

Thank you sir for your help. I will try to reinstall nam and try to run it again. Right now the example given by you gives output
"ns aodv-routing.table.tcl
num_nodes is set 25
INITIALIZE THE LIST xListHead
channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5,  distCST_ = 550.0
SORTING LISTS ...DONE!
"

but no visualization.

[knudfl]

» no visualization « :   Then you have no nam installed.
``aodv-routing.table.tcl´´ has a nam exec entry :      exec nam out.nam &
( Lots of other files.tcl have no nam exec line : You will have to run 'nam out.nam'.

You can also build your own nam, with ns-allinone-2.35_gcc482.tar.gz = the Oct 2014 update
https://drive.google.com/file/d/0B7S255p3kFXNSGJCZ2YzUGJDVk0/view?usp=sharing
The old year 2011 " ns-allinone-2.35.tar.gz" can often fail with nam. ( And other things.)

Building nam-1.15 :

tar xvf ns-allinone-2.35_gcc482.tar.gz
cd ns-allinone-2.35/
./install
cd nam-1.15/
sudo make install

-

[Nidhi Chhajed]

Thank you sir..

I am using older version thats why this problem occurs. Now I will reinstall the attached version and try to run the files.

[Nidhi Chhajed]

Dear sir,

After installing the version provided by you, it also gives error " nam
Segmentation fault (core dumped)

Respected sir,

When I checked nam, it shows that it is already installed but is unable to locate ns2.

I am trying to uninstall ns2 but not able to do so.
What should I do?

[Nidhi Chhajed]

Hello sir,

After installing ns-2 I got the following error-

Please do not show  / attach images with text.
I guess you know how to copy/paste a text to a file.

About removing nam :
`nam-1.15-3´ is the Ubuntu package from Ubuntu you will have to remove :
$ sudo apt-get remove nam

The package nam-1.15-10** you have in Documents : Please install the package.
I guess you never tried to install it, as it would normally update the faulty package installed with apt.

About removing ns-allinone-2** : apt can only remove packages.deb installed with apt.
Removing folders : Delete the folder → → $ rm -r ns-allinone-2.35/
Besides that : You can have as many ns-allinone-2.35 as you want, installed at the same time.
... But do never add any *PATH text to .bashrc. Not required.
How to install ns : $ cd ns-2.35/ && sudo make install
→ 'make install' will install 'ns' to a system PATH.

-

[Nidhi Chhajed]

Thank you sir for your valuable suggestion. I have removed ns2 and reinstalling it with the new one.

The in-build nam folder in ns2.35 64 bit is also nam 1.15 64 bit or not?

Hello sir,

I have installed ns2 and nam but after adding new protocol, I am not able to reconfigure ns2. It shows the following error -
"nidhi@nidhi-Inspiron-3542:~/ns-allinone-2.35/ns-2.35$ ./configure
./configure: line 2097: config.log: Permission denied
./configure: line 2107: config.log: Permission denied
"

How to get permission? please let me know.

[Nidhi Chhajed]

Problem resolved Sir..

But after reconfiguration nam has stopped working. Again segmentation fault error occurs :-(. What to do?

[knudfl]

»» .. after reconfiguration nam has stopped working ««. ? After reconfiguration of what ?

When you start at building a new ns-allinone-2.3x/, the first thing to do is :
Delete the folder  nam-1.1x/.
Then you are not at risk building another faulty nam.

"Segmentation fault" usually only happens when the Ubuntu "nam package" is installed.
( $ sudo apt-get remove nam ).
General nam solution : Use a package from this link,  #2

After reconfiguration of ns2.35 nam has given segmentation fault error.

I have removed nam using "apt-get remove nam"and also delete nam folder from ns-allinone-2.35.

After doing this I copied nam-1.15 64 bit in the ns-allinone-2.35 folder and reinstall nam by using "sudo apt-get install --reinstall nam libotcl1 libtclcl1". but the error remains same as-

How do I install nam-1.15 instead of default nam provided ubuntu?

Also the nam folder which I have deleted contains lots of files and folders in it, but the nam folder extracted by me contains only two folders named DEBIAN and usr.

Can you tell me sir that What is the thing missed by me.

Ok sir..I will retry installing nam. I din't know that nam can be installed directly by clicking it.

[Nidhi Chhajed]

Thank you so much sir.. It works perfectly.

Can you please tell me how I can use the new protocol in ns2.

[knudfl]

»» how I can use the new protocol in ns2 ««.

Is it a default "Security" as from ``security_ns235.patch´´ ? ?
.  http://www.linuxquestions.org/questions/tags/security-ns2/
.  https://groups.google.com/forum/?fromgroups#!searchin/ns-users/security|sort:date
My test :

$ ns235-security security.tcl

-

[Nidhi Chhajed]

No sir, It is not default security package. I have to create a new security protocol, thus needed help in patching the files with ns2 and then executing it. But I never use ns2 before so I don't have any idea about it. I have to add a C program file in aodv and make changes in it. What can be the solution?

Hello sir,

When I used commands for adding new objects according to the instructions given by you as -
"Compiling new objects : cd ns-allinone-2.35/ns-2.35/ && ./configure
&& make clean && make : A new 'ns' will be generated."

After executing make command I found the below output-

make[1]: Leaving directory `/home/nidhi/ns-allinone-2.35/ns-2.35/indep-utils/webtrace-conv/ucb'

Does it means that new objects are added successfully?? How can I test?

»» Does it means that new objects are added successfully ? «« :
May be. If you added new objects.o to the Makefile.in .

And if you also added the right entries in tcl/lib/<files>, you can write a simulation.tcl, and test it.

[Nidhi Chhajed]

Sir i have tested..Ii is added successfully. Thank you. I have to embed RSA code in aodv. Can you help me?? Where the changes should be done?

Hello sir,

How to simulate aodv protocol for calculating throughput, end to end delay, packet delivery ratio? How to calculate size of a packet before transmission / during transmission? Please help.

[knudfl]

Hi.
»» calculating throughput, end to end delay, packet delivery ratio ««.

You may use an awk or perl script to get the information from the trace file.
"awk#perl#python__scripts-10.2015.tar.gz" : ~185 scripts ....
https://drive.google.com/file/d/0B7S255p3kFXNOUIteTVSWjdzQU0/view?usp=sharing

About "size of a packet" :  That's a fixed setting in the simulation-script.tcl, isn't it ?

Some simulations have an Xgraph output with "calculation plots",
see xgraph_ns2-files-tcl_10.2015.tar.gz
https://drive.google.com/file/d/0B7S255p3kFXNSW1YTjFLLVpOWTg/view?usp=sharing

[Nidhi Chhajed]

Hello sir,

I have tried to use aodv.awk given by you..It gives error while executing command
" gawk -f aodv.awk simulate.tr
gawk: aodv.awk:83:
gawk: aodv.awk:83: ^ syntax error
"

but there is nothing in this line.

Sir how can I simulate packet using aodv routing? Please help.

Hi.

"aodv.awk" : The finishing bracket  }  is missing.

[Nidhi Chhajed]

Hello sir,
Thank you for your kind reply, the code runs perfectly.

Is it compulsory to attach agent in every node?

How can we identify that which agent is to be used? For example whether I use TCP, TCPSink,UDP or NULL or any other agent type while creating a simple 10 wireless node scenario.. How can I define source node and destination node in tcl?

[Nidhi Chhajed]

hello sir,

How can I use .c file methods in aodv protocol. How packets can be encrypted during transmission and decryptedafter reception. Please help if you know. Thank you

[Nidhi Chhajed]

What does it mean? Does it mean that the protocol is not added in ns2?

[knudfl]

Hi .

"draodv-routing.table.tcl" : Please attach the file.

-

[Nidhi Chhajed]

Hello sir,

draodv-routing.table.tcl is same as aodv-routing.table.tcl sent by you. I have only changed protocol name from AODV to DRAODV. Rest all is same. I am attaching draodv-routing.table.tcl with this mail. Please check it.

[knudfl]

New protocol : Recompile ns-2.35/ and save the new executable 'ns' as /usr/local/bin/ns-new-name

Your "DRAODV" :

cd ns-2.35/
cp ns ns-draodv
sudo cp draodv /usr/local/bin/
Simulation : ns-draodv draodv-routing.table.tcl

... Only in that way you can be sure you are using the right executable 'ns'.
I.e. your errors indicate the use of an 'ns' with no ``droadv´´ compiled into it.
I.e. i.e. I get the same errors : $ ns-orig draodv-routing.table.tcl
.... where 'ns-orig' of course is an 'ns' with no draodv.

[Nidhi Chhajed]

hello sir,

FOllowing error has encountered while executing tcl file
"ns: finish: couldn't execute "./xgraph": no such file or directory
    while executing
"exec ./xgraph delay.tr packetdelivery.tr -x "Time" -y "No of Packets" -t "Secure Randomized Routing" -bg white &  "
    (procedure "finish" line 10)
    invoked from within
"finish"
"

When I execute "sudo apt-get install xgraph" it gives
"sudo apt-get install ns2 nam xgraph

Reading package lists... Done
Building dependency tree      
Reading state information... Done

ns2 is already the newest version.
xgraph is already the newest version.
nam is already the newest version.

What can I do for this?

@Nidhi Chhajed ,   Hi.

As you can see the command is not xgraph but ./xgraph.
./xgraph means an xgraph executable in the current directory.

Just edit ./xgraph to xgraph
