The paper I refer is "Routing Stability in Static Wireless Mesh Networks"
Krishna Ramachandran, Irfan Sheriff, Elizabeth Belding, Kevin Almeroth
University of California, Santa Barbara

The rapid route change is an advantage in case of variable and
unstable wireless link, but can become a problem in case of multiple
available "good" links. In my opinion, in this case useless route
change happens, maybe for a temporary throughput improvement, so it is
important to protect current good route from route flapping.

I hope I've been clear.
