I already tried changing TQ_GLOBAL_WINDOW_SIZE to 5 instead of 10 and
that helped. Changing it to one is interesting. I've not tried it yet,
but i would of thought some ring buffer was needed to handle the 0s
which are added when originator messages are received for other
neighbors. 

I already tried reducing the hop penalty. However testing showed it
behaved worse. This i don't understand. So i'm guessing my test setup
changed between my different tests. So i need to run the test again,
both the control and the modified hop penalty.

What ideas do you have for improving the algorithms. Depending on the
scale of work needed i might have some time to do some coding.
