[OLSR-users] Network stability

Hey John.

Hmmm. So the user's link to the tower times out on a regular basis which 
then causes the indirect route via another user's node to be taken to 
the tower?

If so, you might want to increase the HelloValidityTime and the 
TcValidityTime to, say, twice or three times their original values in 
order to not use the link.

You should then also change HystScaling to something smooth, e.g. 0.1, 
which will make hysteresis less sensitive to changes in the link 
quality. Moreover, you could lower HystThrHigh to something like 0.6 and 
HystThrLow to something like 0.2, the effect being that the link is more 
easily accepted as established by hysteresis (hysteresis value higher 
than HystThrHigh) and less prone to being rated as broken (hysteresis 
value lower than HystThrLow).

(You're still not using link quality, right?)
