simonduq dd8576830e Added bursts support in CSMA/ContikiMAC, and CFS-swapping in 
queuebuf. Exemplified in examples/udp-stream.
 2011-09-27 16:47:03 +02:00
Joakim Eriksson ab049ec704 some fixes to cut some extension headers before TCP processing 2011-09-22 17:22:59 +02:00
nvt ab0c04b041 Move 16-bit integer conversion operations into functions, as is done already with 32-bit ops. 2011-09-06 17:28:39 +02:00
nvt 942ba1f7bd Removed const qualifier to conform with the rest of the Rime interface. 2011-09-05 22:05:41 +02:00
Niko Pollner 84105f4e47 Improved multihop/mesh route discovery. 
Packetbuffer is now saved before route discovery and resent when a
route is found.

This solves the following problems:
- First packet sent to a certain node is corrupted.
- Packet to be forwarded that triggers route discovery is lost.

Adam Dunkels f7a3a8476f Added a safeguard to fragmentation reassembly: if there are additional bytes in the final fragment, we shave them off in the spirit of being 'liberal in what we accept' 2011-09-05 14:26:48 +02:00
Joakim Eriksson 7b50b87e12 Merge branch 'master' of ssh://contiki.git.sourceforge.net/gitroot/contiki/contiki 2011-09-05 11:40:22 +02:00

Adam Dunkels 9b53b3aa8e Small spelling bugfix 2011-09-02 13:51:28 +02:00
Adam Dunkels 2da65385a0 Added a SICSLOWPAN_CONF_COMPRESSION_THRESHOLD that can be used to set a threshold under which header compression should not be used. Below this threshold, headers are not compressed but sent as full IPv6 packets. This is useful for RDC layers, such as ContikiMAC, which set a lower bound for packet size. 2011-09-02 13:51:09 +02:00
Adam Dunkels 3cb42ceb10 Made the ContikiMAC header configurable from contiki-conf.h 2011-09-02 13:37:46 +02:00

 2011-07-11 16:52:45 +02:00
Vincent Brillault 2ac91d53b5 Add (dangerous) feature : use layer 2 acks instead of NUD in the IPv6 layer. 
(Decrease packet numbers but dangerous if neighbors change their ips (not a problem in standard RPL with EUI-64 based addresses))
 2011-07-11 14:19:14 +02:00
Vincent Brillault 6ddd0bb190 Allow to completely desactivate DAD (useless in route-over LLN as implemented, see http://tools.ietf.org/html/draft-ietf-6lowpan-nd-15#section-8.2) 2011-07-11 13:51:38 +02:00

Oliver Schmidt 07f3df45be Converted scope-local variables into function-local variables. 
The 6502-specific LC implementation doesn't allow for scope-local vaiables between PT_BEGIN/PROCESS_BEGIN/PSOCK_BEGIN and PT_BEGIN/PROCESS_END/PSOCK_END.

nvt a093c262ee Improved objective function API so DAG metric containers can be generated cleanly. The packet generation now asks the OF to provide a fresh logical presentation of the metric container, which is then translated to raw packet format. 2011-02-15 01:13:30 +01:00
Adam Dunkels db37e38156 Make sure we don't remove the preferred parent 2011-02-14 23:01:11 +01:00

Adam Dunkels e980072817 Don't add neighbor as a potential parent if its rank is too high. 2011-02-13 18:05:28 +01:00
Adam Dunkels 2a96835c05 Don't remove all parents that have a worse rank than an incoming DIO: we may inadvertently remove our preferred parent. Instead, remove parents with a rank that is worse than our preferred parent. If we are lucky, this will give us enough space for the new parent. 2011-02-13 14:16:15 +01:00
Adam Dunkels f1ac94e415 Slight code complexity reduction 2011-02-13 14:14:49 +01:00
Adam Dunkels 3a824d0ed6 Added a hysteresis when choosing a new parent: don't switch parent unless the ETX is significantly better (1.5 ETX better). 2011-02-13 14:14:16 +01:00

Adam Dunkels 706045120f Changed the variable name local_confidence to etx to better reflect what it was used for 2011-02-11 14:18:57 +01:00
Adam Dunkels ba6bf7dd6b Rewrote the parent selection to favour parents with a low ETX and a good rank. The old parent selection would always favour parents with a lower rank, regardless of their ETX, which in some cases lead to suboptimal parent selections. Also, the old code was buggy in that it would always pick the worst parent (the one with the highest ETX). 2011-02-11 14:17:26 +01:00

adamdunkels 09c223f549 Updated Contiki X-MAC to use hardware acks, which allows for tighter timing and results in a lower duty cycle. Hardware acks also make X-MAC more robust against packet losses, as there is a direct way for the CSMA layer to detect loss of data packets. Before, Contiki X-MAC only detected loss of strobes. 2011-01-25 14:31:09 +00:00
adamdunkels d51e99a3dd Updated streaming mode to use only about 20% radio. Made guard time more conservative due to problem report by Ricklef Wohlers. 2011-01-25 14:29:46 +00:00

adamdunkels 26e3b6fdc0 Bugfix by Simon Duquennoy: don't transmit packet until previous packet has been sent by the RDC layer. 2011-01-13 19:06:22 +00:00
adamdunkels 81d23a3a36 Minor bugfixes pertaining to queue handling: if a packet was explicitly dropped, the packet would later be acknowledged despite it never being received; added a limit on how many queue entries that can be used for packets that are being forwarded, to allow for originated packets even if the forwarding queue is filled. 2011-01-10 15:10:43 +00:00
adamdunkels 70f9f075a0 Safeguard against NULL arguments 2011-01-10 15:08:52 +00:00
adamdunkels 148bd60fe1 Bugfix: the defensive retransmission timer setting must be made before the packet is transmitted, otherwise the retransmission timer will always be for the defensive retransmit 2011-01-09 23:49:27 +00:00
adamdunkels 50a3e6ea23 Increased the max ETX to allow for longer paths even with the initial conservative ETX estimate; made collect use announcements by default 2011-01-09 23:48:33 +00:00
adamdunkels acf45ec648 Bugfix: memory wasn't freed when a neighbor was dropped from the list. Also increase the max age to 180 minutes to allow for regular beacons to refresh the neighbor before it is dropped. 2011-01-09 21:20:05 +00:00
adamdunkels 90dc0ceebf Replaced default link estimator with an exponential weighted moving average, which reduces memory consumption per neighbor. 2011-01-09 21:14:22 +00:00
adamdunkels 4e91d9303e Added safeguard timer if the MAC layer would fail to call back after transmission. 2011-01-09 21:13:20 +00:00

adamdunkels 4914739e5d Revived the timesynch module, which has been switched off since the introduction of the new radio API after Contiki 2.4. The new code uses explicit timestamp messages instead of piggybacking timestamps on every transmission. It is also significantly better in terms of exactness. 2010-12-16 22:47:38 +00:00
adamdunkels 10fb99a89d Reduced the value of the max depth, so that a count-to-infinity loop will not count too long before hitting the maximum value. This is important when a network loses its sink, so that packets are not forwarded around the network for ever. 2010-12-16 22:46:34 +00:00
adamdunkels 19e930e6f2 Changed the behaviour of retransmissions to work better with the in-order CSMA code. The retransmission timer is now set when the packet is known to be sent by the MAC layer. 2010-12-16 22:45:15 +00:00
