adamdunkels 822149f943 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
 2009-12-06 13:16:59 +00:00

nifi bb0ffe0478 moved rime initialization into rime router so it is easier to switch IPv6 routing module 2009-11-18 13:51:55 +00:00
fros4943 0034fd7bca generic return values for sent packet 2009-11-13 10:09:02 +00:00
fros4943 9b20f11cd8 chameleon returns 1 only on successful rime_output() 2009-11-13 09:14:52 +00:00
fros4943 583dd11c55 rime_output() now returns RIME_OK or RIME_ERR depending on the MAC return value. 
this patch may affect Rime sniffers running on top of MAC protocols that do not yet return generic MAC return values
 2009-11-13 09:10:24 +00:00
fros4943 26bb5ecd21 added radio and MAC generic return values to allow applications finding out whether the packet was transmitted 2009-11-13 08:59:22 +00:00
joxe 5b0b36c39e accept messages to all routers if UIP_CONF_ROUTER is set. 2009-11-12 14:05:42 +00:00

adamdunkels 56218aba3b Made rimeaddr_t pointers const where they should be. 2009-11-08 19:40:16 +00:00
adamdunkels 70fc23ac7e Enable stream mode by default, remove LED debug mode 2009-11-04 16:02:45 +00:00
adamdunkels 5aab2eb77d A simple addition with significant performance implications: 
sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM
flag, which makes the underlying power-saving MAC layer keep the radio
on for some time after transmitting the packet. This allows reply
packets to be processed directly, significantly increasing TCP latency
and throughput.

adamdunkels c7a91ad4a2 Bugfix: UIP_TCP_BUF -> BUF 2009-10-27 23:09:58 +00:00
adamdunkels 631af06c7c Bugfix: Active TCP connections in uIP are made by first setting up the 
TCP connection state, then poll uIP to send out the first SYN. Until
now, however, the SYN was not sent as part of the poll, but at the
first retransmission. This is now fixed.

adamdunkels 9ec57d61ad Added MAC layer framing support to X-MAC so that packets now are standard 802.15.4 frames 2009-10-19 20:53:56 +00:00
adamdunkels 4de1816e36 Added a new module called "framer" that creates MAC level frames to 
the packetbuf from packet attributes. Two framer modules are included,
one that creates 802.15.4 frame headers, and one that creates a
minimal "nullmac"-style header that only contains the link-local
addresses.

adamdunkels fb037e0afb Added function for sending an UDP packet to a specified IP address and port number over an existing UDP connection 2009-10-18 22:02:01 +00:00
adamdunkels 9d26bd663e A new optimization to X-MAC: senders now keep track of when neighbors 
last were known to be awake. When sending a packet, a sender does not
start to send strobes until the neighbor is expected to be awake. This
reduces power consumption for senders and decreases the contention in
the network as there are less packets in the air. Additionally, the
ACK optimization was improved so that data/ack exchanges now are
more efficient.
