adamdunkels	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

adamdunkels	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.	2010-03-14 22:59:23 +00:00
adamdunkels	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
