[Olsr-users] Getting OLSRD to "switch" faster

[Julie Workman]

Hi.

I am using OLSRD 0.5.6-r5-r10.5 for a robotics application.  My problem is
that when my robot rounds a corner I need to to switch much more quickly to
a better node.  The result using OLSRD unmodified is that I lose
communications for 2 minutes and my robot sits there before the new node is
switched to and I can communicate again.

The odd thing is that when I have several nodes all in sight of each other,
the bot switches quite nicely (~5 seconds) between the closest one at the
time.  It is just when I round a corner (and completely lose communication
with my current node) where I see the 2 minute switch over time.

I have messed around with the HelloInterval, the LinkQualityWinSize, and
HelloValidityTime to where the switch over time is down to 30-45 seconds.
Better, but still not nearly quick enough.

I have several questions.  Can I tweak those parameters further to see
better times?  How small can I make my HelloInterval?  Are there different
parameters I should be changing?  Does OLSRD always work off of packet
loss?  I need about a Mb of throughput for my application.  Are there ways
to tweak OLSRD to use throughput instead?

Thank you for any help/suggestions.
