hello, all,
I'm simulating apps/tests/TestNetwork with Tossim under TinyOS 2.0.2.
It's found that there are always duplicate receiving on the root node .
Is it because of the mechanism of acknowledgment in the CTP? As I find that
nodes often send, or forward, one packet for several times after "no acked" is
reported each time. I imagine that, althought "no acked" is reported, sometimes
the packet has send successfully and received by the root, and once
retransmitting, duplicate happens.
So, I suppose that there is something wrong with the acknowledgment mechanism.
Is it ?
And if it is, how can I improve it?
Thanks.
