I'm trying to find a way to change the gain of a radio link in TOSSIM
(from CVS) midway through the simulation. I didn't see a function
specifically for changing the gain of a link already added, so I thought
I would remove the original link and re-add it with a new gain.
Something like this in C (this is a bit contrived):
Tossim* t = new Tossim(NULL);
t->radio()->add(0, 1, -50);
t->radio()->add(1, 0, -50);
t->radio()->add(1, 2, -120);
t->radio()->add(2, 1, -50);
for (int i = 0; i < 10000; i++)
t->runNextEvent();
t->radio()->remove(1, 2);
t->radio()->add(1, 2, -50);
for (int i = 0; i < 10000; i++)
t->runNextEvent();
However, I get a segfault when trying to remove the link. I believe
this is because of a bug in sim_gain_remove() when you remove the link
most recently added for a given source. I tried to fix that, but then I
just ended up with other crashes when messages were trying to be sent
and such. Any ideas?
Thanks,
Ryan
