Sir, I have searched the implementation of olsr routing protocol in matalb still i haven't found.

MPR selection is the one of tedious process in my project work sir please help me sir.

So what if it is tedious? You have told us that you looked for where someone else had done this, and you could not find it. So now you are asking us to give it to you. Time to sit down and do your work. It is YOUR work after all.

If you actually have a real question instead of just a plea for someone to do your work, then ask it.
