Hello.
I have a problem testing my application using TOSSIM. I have set up a
network consisting of ten nodes with radio links and noise model set
up. The part of my application I am having problems with does some
kind of flood routing. Three out of the 10 nodes start broadcasting
packets, and all the nodes that receive those broadcast them again and
so forth.
Now the problem is that there is packet loss: not all messages that
should be (and are) generated are received by the nodes in range. Also
the packets lost are not the same in each tossim run, the loss is non-
deterministic. I added a timer with a random intervall that delays the
packets for some time on each node, and more messages came trough, so
it seems it's a collision problem?!
But as far as I remember the CC2420 chip does CSMA, doesn't it? Or do
I have to activate it? Does the problem have any other cause you might
know about?
Thank you.
Philipp
