[Tinyos-devel] handling FTSP packets with errors

[Omprakash Gnawali]

If a packet seems inconsistent (ENTRY_THROWOUT_LIMIT), FTSP will not
only discard that packet, but ignore rest of the packets with the same
root+sequence number, regardless of the packet origin. The latter
seems overly aggressive unless there is an evidence that inconsistency
is correlated in sequence number even across the nodes. If there is no
evidence of that, it might be better to allow the possibility of
"good" packets following "bad" packets with the same sequnence number.
Consider the possibility of running FTSP with TS_TIMER_MODE, there is
one node with some problem, and due to phase of the timer, this node
might always send the first "bad" beacon in a neighborhood for every
sequence number...
