121ca946e1 Improved phase lock behaviour when neighbor is not duty cycling: senders notify receivers via the 802.15.4 pending bit that they are not duty cycling. Neighbors then will start sending packets immediately and not wait for neighbors' phase. Tweaking of ContikiMAC timers to make it more reliable. 2010-04-03 13:28:30 +00:00

7bab9316da Two major changes:
* Low-power streaming. Experimental support for a low-power mode which
  allows rapid exchange of packets with a 16% duty cycle. Does not
  seem to function correctly yet though.

* Phase locking. When the phase of a neighbor has been detected, the
  sender assumes that the neighbor will keeps it phase and does not
  send more strobes than necessary to hit the receiver's channel
  check - even if the receiver does not acknowledge the reception of
  the strobes when it should have been awake. Instead, the sender
  stops strobing and tries again at a later time.

410d860a93 Improved handling of neighbor phase estimation: instead of busy-waiting while waiting for neighbor's phase, the new code schedules a timer just before neighbor wakes up 2010-02-28 20:19:47 +00:00
