8dbd2b2337 Significant power consumption optimization: LPP now keeps track of encounters with neighbors and uses this information to keep the radio switched off longer. 2009-04-03 19:59:22 +00:00

1d86b01bfb Made optimizations explicit (and configurable). Added missing initialization of dutycycle protothread. Reduced default listen time and off time. 2009-04-03 11:45:06 +00:00

04101aae36 Fixed alignment problem on the MSP430, where the LPP header may be misaligned 2009-03-31 17:39:54 +00:00

e2cc8b2a3e send all queued packet once we have the chance. 2009-03-31 14:44:13 +00:00

1d47e2a8da send immediate probes only if the packet is directed to us.
sleep for OFF_TIME if the queue is empty.

restrict double packet lifetime timeouts to unicast packets.

stop ctimer in remove_queued_packet in case the function is not called
via the ctimer callback. it could overwrite a valid packet otherwise.

dd082f7fcf improvements to lpp based on code from Adam and discussions with Thiemo.
* queue multiple packets
* send a strobe back immediately after receiving a data packet
* double the packet lifetime to allow for a missed probe

fb8fab739a Renamed the rimebuf module to packetbuf to signal that the module is used outside of a pure Rime context (e.g., the sicslowpan code uses it). 2009-03-12 23:04:52 +00:00

dc7491f810 Bugfix and optimization: X-MAC did not properly switch the radio off after sending a packet, resulting in increased power consumption. For packets that require an ACK, we can let the radio be on in anticipation of the ACK (controlled with an WITH_ACK_OPTIMIZATION option) 2009-03-05 19:37:52 +00:00
