To add a module in Ns-2
is not a simple task especially for beginner. There are two cases in which the
NS2 need to be recompiled.
1. Modifying the
existing algorithm (use the same header and the C++ source files)
2. Adding new
files/Protocols (adding new header and C++ source files)
Modifying the
Existing Algorithm:
Step 1: open the shell
prompt and go to the ns-allinone-2.34/ns-2.34/ folder(there are 3 makefiles,
Makefile.vc, Makefile, Makefile.in, for adding any new file should be done at
the Makefile.in file)
Step 2: Once the existing algorithm is changed, go to
step 1.
Step 3: execute the following command,
make clean
make depend
make
If you have no errors in
the modified code, then the compilation will be success and NS will be created,
else you may get errors, which needs to be fixed.
Step 4: Test your TCL script for the new algorithm.
Adding New Protocol:
Step 1: open the shell prompt and go to the
/home/user/ns-allinone-2.34/ns-2.34/ folder(there are 3 makefiles namely
Makefile.vc, Makefile, Makefile.in, for adding any new file should be done at
the Makefile.in file)
Step 2: You may create new header and C++ source files
for your new proposed algorithm and hence you need to tell that information to
the Makefile.in (which is available in ns-allinone-2.34/ns-2.34/).
Step 3: Put all your files inside a respective folder
under the folder /home/user/ns-allinone-2.34/ns-2.34/
Step 4: Now open the Makefile.in using any editor
(usually vi or gedit) and add the folder information to the OBJ_CC variable)
Step 5: anywhere inside the OBJ_CC variable, put the
New file/folder information.
For example: "newfolder/newfile.o
\"
Step 6: after editing the file entry, follow these
procedures:
- Go to NS2 location in terminal (If you are using ns-allinone-2.xx, then go to ns-allinone-2.xx/ns2x)
- Then type "./configure" in terminal (The Makefile will be replaced with modified one.)
- Then type "make clean" (*optional))[use this, If you want to recompile the whole ns2. This will remove all the object files in NS2].
- Then type "make" [this will make all object files which are missing]
If you have no errors in
your modified code, then the compilation will be success, else you may get
errors, which needs to be corrected.
Step 7: Now test your TCL script for the new protocol.

hi,
ReplyDeleteI define a new protocol in NS name Buddy. I create 3 files Buddy.cpp, Buddy.h and Buddy_packet.h
after run make command, i get some errors for i.e
Buddy.h: error: ip.h: No such file or directory
i use ip.h header file in Buddy.h
although ip.h is not missing, this error happen.
is it possible to help me?
Reply
Yeh, u need to include the ip.h file....
Deletein the mean time, you have to define the new packet structure in the packet.h too else how it will recognize your packet i.e. buddy_packet, during run time...
So, just go to ip.h and packet.h and see, there are few packet definitions already exists, in the similar way, you need to define for your packet too.... now compile the NS, and proceed...
All the best.. :)

hi, i have added new module in ns2.33 but aftr 'make' am getting error like
ReplyDeletemake: *** [common/scheduler.o] Error 1
can u plzz help me to resolve this error
HI,
DeleteAs you have added new modules/files and running the MAKE command, However, your ns code is not able to create "scheduler.o" file which is located in the common folder. There might have some error or dependency missing in Scheduler.cc or in Schedule.h. Please check it care fully and proceed . Good Luck
thank you

ReplyDeletesir i got make.in file.but it is empty.i have to change cc file of aodv.plz help me. give proper steps for it
ReplyDeleteModifying the Existing Algorithm, you just add the new piece of code in the respective CC file and the go to the terminal and follow the steps given in Modifying the Existing Algorithm:" part only. if you open the Make file, it will show nothing... this is just an executable file.
DeleteThe "Makefile.in" contains all the dependencies and from there we just run the ./configure command to get the new MAKE file.
for you case just make changes in the aodv.cc file and run the three necessary commands, i.e make clean, make depend and make. this much will reflect the changes you have made..
Thank you..!! HK :)
i had copied existing red.cc red.h in queue and renamed as mdred.cc mdred.h ,and performed above given steps,and also executed the tcl script with mdred .it executed correctly but when i added the new varibles to mdred.h and mdred.cc and again performnig the above steps, i executed tcl scipt as before but it is showing segmentation fault how to remove.y i am getting this error how to solve it
ReplyDeletesegmentation fault usually comes, when you access variables that are not initialized properly. I guess the error is with the new variables. please go to place where you declared the new variables, make the changes carefully and you also need to reflect the necessary changes in other related files as well.

hi how to create clusters in tcl and to choose cluster head
ReplyDeleteHi,
DeleteIn general cluster are two types: static and dynamic.
Static Cluster can be formed by placing all nodes fixed and selecting few nodes as cluster heads and, data exchange between cluster headscab be achomplished using any clustering algorithm. This can be done using the TCL Script. Please find the URL, where you will find the TCL code for LEACH (popular sensor network protocol). Just go through it and learn how to form statc cluster using TCL scprit.
http://www.codeforge.com/read/238167/leach.tcl__html
For Dynamic cluster, youi have to use the random movement feature and is bit difficult. But this can also be implemented using NS2. Here you need to make some changes in the core code of the NS.
Hope i have answered your quetion. :)

hello,
ReplyDeletethis post to add new module in ns2 is really helpful.
i am working on a project to add a new code and i applied the steps for adding new module, obj file is created successfully in the respective folder but when i tried tcl file with ns command it shows 'Segmentation Fault'.
i removed the added file, tried to recompile ns again. the prior codes which have been running successfully are showing the same error when executing.
can you please tell me the solution.. i only know that ns is not completely generated.
thank you..
hi please let me know what module you are trying to implement ,have you tried the same with any other tcl script
DeleteDear Anonymous,
DeleteThank you very much for your complements.. :)
As the obj file is created successfully, there is no problem with the procedure. There may have some bugs in the new code itself (Say array was accessed wrongly or variables which are not declared correctly are accessed during the execution),
Please go through the newly added code and check carefully for the bugs. Placing checkpoints (i.e. using printf() statements) and checking is an hit and trail method to find the location of the segmentation fault...
All the best... :)

Hema
hi,
DeleteThanks for the suggestions..
The "segmentation fault" is coming for even typing ns only, after running ./configure and make commands... seems ns is crashed (I have not executed my code yet). Before that ns is working properly. nam and xgraph is working fine everytime.
Is it possible that any flag setting or any path setting changed ?
After reinstalling ns2, previous scripts work fine.
In your case, it seems you have some bug in the new patch or module you are adding to NS. What is the new module you are trying to add?? Please make sure the patch is in working condition.
DeleteI must thank you for providing guidance on ns2.I am facing an issue.I have installed ns2.31 with crn patch.Now, if I use make depend and make command,it says permission denied.Please help me out.I use ubuntu 13.10.I find locks on certain folders in allinone folder.

Thanks for helping me out.I have now installed ns-allinone-2.31 with crcn patch.I want to add database capability to it while assigning channels for mobile nodes.I have completed accessing database tables from tcl script.I want to provide channel selection capability using the channel usage history and assigning it based on idle time.Please help me out to find the location where modifications are to be made.Thanking you
DeleteHi, You can store the channel usage history in a separate file(may be .txt file) and require to implement the new channel selection capability in the in the .cc files. The best place add the part of the code is the MAC protocol file you are supposed to use for simulation. In the code itself you have to access the "channel usage history file" and perform the selection part. To the best of my knowledge, this the MAC file is the best place to adopt the selection changes.
DeleteAll the best... :)
Sir,
ReplyDeleteI made some changes in .cc files and now i want to run make command it will give error trace/trace-ip.o: file not recognized: file trucncated collect2: ld returned 1 exit status
please help
Have you made any changes in the trace files?? If yes, be sure the changes do not contain any errors which are not allowing the creation of object file (.o file). You have an error with generation of the "trace-ip.cc"'s object file. Also check in the "Makefile.in", you might have made some changes unknowingly.
Deleteif i execute make clean command the i get the following error
ReplyDeletemake: *** No rule to make target `clean'. Stop.
Navigate to the folder, where your NS files are present. Then execute the "make clean" command.
DeleteI navigated to the folder ns-allinone-2.xx/ns2x and executed the command and I'm still getting the same error.
DeleteUse the terminal and navigate to the NS folder (where your ns executable is present) and run the following commands and reply me with the errors you are getting.

hello sir..i am working with the aggregating clustering with AODV. ,but confused how to start, If u provide me tcl script of clustering in MANET , i shall be very much obliged to you.
ReplyDeleteHi,
DeleteFor aggregating clustering with AODV, Only TCL script is not enough you have to make changes in the AODV.CC file well. Then, using the TCL script to call the function responsible for aggregating clustering. The clustering logic should be placed in AODV.CC file
Sorry, currently i don't have any files with me. Probable you will get the logic on some in some research article.
You are welcome to discuss if any more issues are there. Thank you..!!
That clustering algorithm should be in leach protocol thanks !!!!

ReplyDeletesir, how to use protocols given in src folder ?
ReplyDelete1)I want to debug tcp.cc file,and want to see all printf statement what are there in traceall () function .Is there any way to do this?
ReplyDelete2) when I recompile ns2 with ./configure make,make clean it executes ,/configure well but for the rest two it gives an error like
make:***** no rules to make target 'make clean'.stop
Please guide me in this regard
To see all the options in the traceall() function, you have to manually either dump them into a file or print them on the output screen. The earlier option is a better one to analyze easily.
DeleteRegarding the error, The steps are as follows:
> make clean
> make depend
> make
Make depend is also important as it creates the necessary dependencies for creating the object file. Try the above sequence of commands.
I tries to add a new protocol in ns2.35. the command .configure and make clean is done but when I tries to make I encountered some error.

what sould I do.
Does the new protocol have any associated header files, where the function declaration is done. Do check for the same and add them in the Makefile.in as well.
DeleteCheck, where the "rtable_.lookup" declaration/definition is located and add all the files in the makefile. Hope this will suffice the purpose for a clean compilation.
