nvt 01b7a4f7f2 Replaced ROOT_RANK with a macro that allows for other min_hoprankinc parameters than the default. Also made some minor style improvements. 2011-02-20 20:15:40 +01:00
Mariano Alvira bb1baffc79 change FIX2ETX -> NEIGHBOR_INFO_FIX2ETX in some debug prints. 2011-02-17 20:54:57 -05:00
Nicolas Tsiftes 93a7280a1a Replaced old description 2011-02-15 18:10:15 +01:00
nvt 99d0387a8e Merge branch 'master' of github.com:adamdunkels/contiki-2.x 2011-02-15 01:13:41 +01:00
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
nvt cbe4513bf4 basic support for parsing metric containers in DIOs 2011-02-13 23:17:56 +01:00
nvt 539ff33104 Turn off debugging 2011-02-13 21:36:07 +01:00

nvt 5ec2f19dc9 Remove only the worst parent if the table is full when processing a DIO. 2011-02-13 21:33:47 +01:00
Adam Dunkels 432928d000 Changed the name of macros defined in neighbor-info.h to have the NEIGHBOR_INFO prefix. 2011-02-13 21:29:59 +01:00

Adam Dunkels 15bf73ba08 Use DAG_RANK() macro to compute rank 2011-02-13 19:01:15 +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
Joakim Eriksson 48fb9dda9e fixed of0 to respect min hop rank increase 2011-02-13 11:25:53 +01:00
nvt 20171985c6 Split the RPL header into a private and a public header. 2011-02-11 16:21:17 +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
Adam Dunkels bb8377dfee Set the end-of-stream flag on the TCP FIN packet 2011-02-10 22:47:45 +01:00
Joakim Eriksson d24c63c0f1 fixed so that minhoprankinc is configurable 2011-02-10 19:44:12 +01:00
Adam Dunkels 8d55a68ebe Added a PACKETBUF_ATTR_STREAM_END packet flag 2011-02-08 22:20:07 +01:00
Adam Dunkels 46348d9013 Added the low-power streaming mode where frequent channel checks are performed when streaming is on. Enabling this will (by setting WITH_STREAMING to 1), however, significantly slow down Cooja/MSPsim simulations. 2011-02-08 21:57:46 +01:00
Joakim Eriksson d518c84471 made rank calculation depend on selected parent when joining DAG 2011-02-08 19:59:50 +01:00
Nicolas Tsiftes aeca16d01f Just update the node rank and let rpl_process_parent_event take care of the rest 2011-02-07 17:29:23 +01:00
Nicolas Tsiftes e3638d2791 Updated to the minrank-hysteresis OF 2011-02-04 15:46:01 +01:00
joxe 389a4f9220 added rpl-all-nodes multicast address to nodes mcast addresses 2011-01-25 22:41:30 +00:00
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 fa524fabd7 Bugfix: q->buf was not tested for NULL, as it should be. Fix by Simon Duquennoy. 2011-01-25 14:24:38 +00:00
joxe e79c0ab1ee fixed rpl so that it sends and receives on the rpl-all-nodes multicast address 2011-01-25 09:55:12 +00:00
joxe 3a643fa0c6 added address macros for rpl-all-nodes 2011-01-25 09:54:03 +00:00
adamdunkels 4b4b8fad56 More recent packet entries. Allow 4 queue entries to be dedicated to generated packets. 2011-01-18 16:05:53 +00:00
adamdunkels 808c21fbfa Bugfix: default should be 3 MAC-level retransmissions if collissions or loss occurs 2011-01-18 16:03:57 +00:00
adamdunkels affba785b5 Enabled phase-lock only for channel check rates of 32 Hz or lower 2011-01-18 16:03:19 +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 a0960154ba Cleaned up parts of the code; added comments 2011-01-09 21:07:01 +00:00
