Bugfix by Henrik Mäkitaavola: check that ICMP6 process is defined before invoking it
2010-01-25 13:37:05 +00:00
4f3e8d565c
Added a simple CSMA (Carrier Sense Multiple Access) mechanism that
...
works on top of an underlying duty cycling mechanism. The CSMA layer
retransmits packets that could not be sent because of a collision was
detected.
2010-01-25 11:46:44 +00:00
7ad93e5d18
Added a field to the struct mac interface:
...
channel_check_interval(). This function returns the interval by which
the duty cycling mechanism checks the radio channel for activity. It
is used by higher layer mechanisms to determine suitable timeouts for
retransmissions.

Do not remove encounters - there is no need to, as they are only an optimization
2010-01-14 20:14:03 +00:00
f6715890de
Made SENSORS_ACTIVATE() and SENSORS_DEACTIVATE() use non-pointers, for concistency

clear transmission flag if send failed

93c748cc74
Bug fix for mysterious packet loss : check FIFO pin instead of FIFOP pin for any unread RX FIFO data;
...
Added protection of packet timestamp across interrupts. Note that race condition can still occur as interrupts and self-scheduled reads of the RX FIFO interleave in certain unusual patterns. More investigation is needed.

Use RTIMER_NOW() instead of rtimer_arch_now()
2009-12-09 18:08:26 +00:00
eff2203310
There were many bugs in the rtimer code, particularly one that made only one rtimer at a time work. We have a new rtimer system that we're testing, but in the meantime, I rewrote the rtimer code to explicitly support only one rtimer. Makes the code significantly simpler (and fixes a bug that was very hard to track down).

Variable xmac_is_on was used both in interrupt and non-interrupt contexts and needs to be volatile

Bugfix to the Contiki LPP encounter timing code: encounters are now
...
properly timed.

Significant improvements to the Contiki X-MAC:
...
* the code is simplified, particularly the duty cycling logic
* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
collisions
* broadcasts are sent directly, without strobes, reducing the power
consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
strobe ack
