[Tinyos-help] eetx value doesn't increase for neighbors

[Philippe BAYLE]

Hi all, I am working on tinyos 2.x (not the latest CVS release). I am
currently doing modifications on CtpRoutingEngineP.nc file in order  to
choose a parent considering severals parameters such as congestion and
energy in extra of ETX. For that I check all the neighbors in the Routing
Table built in the file. The problem is when a node is no longer alive ( for
example if you move the motes) , it stays in the routing Table....and then
it is considered for the choice of a new parent.
I guess that the link Etx value should avoid to consider bad link but it
doesn't. The link quality must increase in a signifiant way when a neighbor
mote "die" but in fact, towards what I observed, it stays at the same
value....This comes from LinkEstimator component with the eetx value. I know
that there was problems about eetx not increasing in the past but I am using
the revision 1.6 of this file and it should works so I don't understand at
all what happens. Can someone tell me if this is a bug or if the eetx value
only increases when the parent (and not a simple neighbor) is lost?

Thank you, Phil.
