[Olsr-dev] MPR selection algorithm in olsr

[Bidur Devkota]

I am thankful to Teco Boot for those links which were of great help for me.

Further, I am looking if someone could tell about the location of the
function in the OLSR Code which runs the MPR selection algorithm.
I could see something in "src/mpr.c", since this is my first time parsing
the source code, I would be more confident with some more advice from
experienced person. Any resources or tips for beginners which will guide
for understanding and changing code will be of great value for me.

Thanks.
