Hi Everyone,

My name is Augusto and i want to ask your help kindly with this issue;

At this moment i am working in a thesis based on RPL protocol.

Now I want to compare differents perfomance of the OF (MRHOF and OF0) and maybe to use or design a new object function.

but i dont know how can i select or choose an objective funcion for my simulation ?

what file or option i need to modify for this purpose ?

I am using rpl- collect located at /contiki-3.0/examples/ipv6/rpl-collect.

Thanks,
@hlsc1983

Open Makefile.rpl and change rpl-of0.c to rplmrhof.c whenever necessary

HI

I wanna to say you thanks again for your response, and sorry for delay.

I have been working in my thesis, so i looked for the file called (Makefile.RPL)
as you said me but i couldn´t found it, i checked in the folder core/net/Rpl.

Or is located this file (Makefile.RPL)in each project´s folder (like /ipv6/examples/simple-udp) ?
where can i found it ?

Meanwhile for tests i have used the OF MHROF, which is the default OF in contiki-3.0

Thanks again

Hi kamranzahoor, i used this paper https://www.researchgate.net/publication/304572240, when it explains how you can modify and test with diferents OF, but still i couldn´t change or to get results, because i can´t find the file called Makefile.rpl which is mentioned in the paper.

Hi kamranzahoor ,

I attached the file, where you can find a section called " Adjusting Objective Functions", i´ve tried to used it but, how i said in a previous message, i cant find the file Makefile.rpl, located at /home/user/contiki/core/net/rpl.

I will keep for your comments,

Thanks

Hi kamranzahoor ;

Thanks for your response, i am using contiki 3-0, and still i can´t find the file "makefile.rpl" at the folder core/net/rpl ( i attached an image with the files included in this folder ). I have a question, is it just create the file inside the folder or is it necesary other step ?

Hi everybody

First i want to say thanks to everybody, for your responses and attention.

Finally i could set the OF in contiki 3.0, using a file that i posted.

Now i am doing tests and my goal is design a new OF and can add it to rpl folder.

Thanks again

@JamesUribe

Hi sk3110sk, just remember that you need to modify two files: Makefile.rpl and rpl-conf.h.

Hi Mary-hada, in my case only i changed the OF default what is being used by RPL, ( MRHOF or OF0), i did not modify the routing metricos or another parameter.

Open Makefile.rpl and change rpl-of0.c to rplmrhof.c whenever necessary

it doesnt change a thing. see through the compilation files , there is no of0 file compiled..

Meham26 commented Mar 22, 2021

change in make file of contiki/core/net/rpl folder as well as in the rpl-conf.h file of same folder . in rpl-conf.h file , u will find "#define RPL_OF rpl_of0 " just change it to rpl_mrhof and save.. while selecting mote, take it from the contiki folder not contiki 2.7

I'm trying to improve RPL objective function by implementing some new designed metrics in RPL using Contiki/cooja.
Can you please explain the changes to be made in brief?

Hi everyone,
I want to apply different optimization routing algorithms in Cooja. Can you please give me suggestions where to add and how to add the new algorithm?

Thank you for your response. Can you please send any examples regarding that parent selection algorithm? I don't know about Cooja. I am currently doing research on this.

First, you should create your own file, then select the of you created on the conf file. OF is selected as mrhof by default. You can easily do what you want by checking the steps here.

As well as modifying the MRHOF or OF0
But unfortunately, I have not started with that, I am trying to get more information about this work
