Implementing willingness about android-manet-manager

[jrobble]

Hi Aleix,

Yes, in theory it's possible to use the battery state to influence the
willingness value. OLSR states that it already does this:

http://www.olsr.org/docs/report_html/node110.html

I have not done enough investigation to determine if OLSR does or does not
do it on an Android device. According to that link, if you're seeing all
willingness values set to 3, then my assumption is that /proc/apm is not
accessible. You should look into it.

If you had to make any modifications, you would make them to the olsrd C
code, not the SPAN framework:

http://www.olsr.org/?q=mercurial

The precompiled version of olsrd is included with SPAN under /res/raw in
the Eclipse project. The olsrd binary is copied over to
/data/data/org.span/bin on the device when the Manet Manager is installed.

Hi! I was wondering if it's possible that nodes decide to forward or not
to forward packets depending on its battery state. I've seen that OLSR
implements an attribute called willingness that actually does this
function, but for what I've seen in all packets this attribute is set to 3
(unknown), I assume this is because the willingness function it's not
implemented yet.. Am I right?

So if I want to implement this what would I need to do? Modify Node class
and add Willingness attribute related to the battery state of the node and
modify the class OLSRProtocol to take willingness into account?

I'm a bit lost here if anyone can give me some advice would be nice! Ty!
