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
nvt-se	30f5e29db7	dos2unix conversion	2011-01-05 17:01:03 +00:00

dak664	3c3cd868cd	Allow shorter UIP_CONF_WAIT_TIMEOUT for more aggressive power saving modes.	2010-12-24 00:39:04 +00:00
dak664	322d835fee	Fix avr-gcc compiler warnings	2010-12-18 22:12:53 +00:00
nvt-se	8f76c82433	Improved DAO management.	2010-12-17 15:24:25 +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
adamdunkels	4a89cc9db3	Rework of the new CSMA in-order code that fixes a number of smalllish bugs in the in-order code.	2010-12-16 22:44:02 +00:00
adamdunkels	79f2c25dae	Rework of the phase-lock optimization mechanism. There were several bugs in the existing code, such as the phase-lock would lose synchronization when a packet was lost.	2010-12-16 22:43:07 +00:00
adamdunkels	01c28ab502	Added explicit timestamp packet type, for the revived timesynch support	2010-12-16 22:41:43 +00:00
nvt-se	dae3dc22f3	Corrected a comment that was accidentally overwritten in a previous commit	2010-12-15 19:57:40 +00:00
nvt-se	cd08939b38	Corrected the reported ETX in the initial callback, and fixed the coding style	2010-12-15 14:35:07 +00:00

nvt-se	542bbd4b31	Increased the width of dio_next_delay to avoid possible wrappings	2010-12-15 12:24:00 +00:00
nvt-se	486f202d09	Fixed problem with too large values for the DIO timer.	2010-12-15 12:12:27 +00:00
dak664	a026c94467	Fix compiler warnings	2010-12-14 22:45:22 +00:00
dak664	0a4a0ffb32	Add SICSLOWPAN_CONF_ACK_ALL for hardware autoack testing	2010-12-14 22:18:20 +00:00
dak664	240d478c1f	Allow platform to specify COLLECT_CONF_BROADCAST_ANNOUNCEMENT_MAX_TIME	2010-12-14 22:14:33 +00:00
adamdunkels	952dfc9384	Rework of the CSMA layer: instead of using one timer per packet, the module now uses one central timer and a queue of outgoing packets. This helps to keep packets in order, which is extremely useful for TCP transfers, and reduces the amount of congestion since consecutive packets now are spaced in time if there is a collision. Based on the observations and ideas of Simon Duquennoy.	2010-12-14 07:57:14 +00:00
dak664	0e60c99e80	Add defines to set stateful address prefixes.	2010-12-13 23:27:40 +00:00
dak664	9c66df6de1	Fix ancient RAND_MAX compiler warning	2010-12-13 16:52:02 +00:00
joxe	3e293e6cfc	updated rpl dio message format to be compliant with latest version	2010-12-13 10:59:37 +00:00
nvt-se	c9cc87ef25	Added support for Mode of Operation flags in DIOs. Removed obsolete destination advertisement flags.	2010-12-13 10:54:25 +00:00
joxe	b66da85392	fixed comments and initialize flags in dio_output to zero	2010-12-13 09:59:46 +00:00
joxe	aa1795d5c2	removed route annotation from rpl - moved to ds6	2010-12-10 22:48:31 +00:00
joxe	2c30b3c6ba	added annotation for showing routes and default route during simulation	2010-12-10 22:46:58 +00:00
adamdunkels	af21afa750	Make sure that the cycle timing is exact	2010-12-10 13:36:06 +00:00
adamdunkels	e4cf633215	Put parenthesis around user-supplied options. Patch by Roger Larsson	2010-12-07 23:33:17 +00:00
adamdunkels	c19a967973	Bugfix: with the recent bugfixes, it was no longer possible to turn duty cycling back on after it had been turned off	2010-12-07 23:12:54 +00:00
joxe	e1fbb9bba0	changed neighbor state callbacks to occur only at add and remove	2010-12-07 10:36:03 +00:00
nvt-se	b2a28e6fc3	Fixed error reported by Pieter Agten. The reachable time is specified in milliseconds, and must thus be divided by 1000.	2010-12-06 09:48:48 +00:00
adamdunkels	4c9793f428	Let ContikiMAC remember the state that the radio should have when duty cycling is turned off. This fixes a bug in which the radio was turned on after sending, even when NETSTACK_RDC.off(0) was enabled.	2010-12-06 09:08:22 +00:00
dak664	f34e5ec798	Convert implicit printf to PRINTF	2010-12-04 21:06:04 +00:00
dak664	e54d7d6f9c	Fix compiler warnings	2010-12-02 15:55:17 +00:00
adamdunkels	6d556d5c13	Fixed bug with link-layer ACKs. Refactored the ACK reception code.	2010-11-25 08:44:34 +00:00
adamdunkels	2f66db3ded	Added a debug mode that keeps track of where individual queuebufs are allocated, which is useful when debugging queuebuf leakage problems.	2010-11-25 08:43:59 +00:00
nifi	3bd78893e5	Renamed nullrdc to nullrdc-noframer and nullrdc-framer to nullrdc. ... nullrdc (previously nullrdc-framer) is now a RDC implementation that does not do any radio duty cycling but supports link layer addresses and frame format via framer (for example 802.15.4). nullrdc can now be used in the same way as contikimac, xmac, etc. nullrdc-noframer (previously nullrdc) is a null RDC implementation that does not do any radio duty cycling, does not add any header of its own to the packets, and does not support link layer addresses.	2010-11-23 18:11:00 +00:00
dak664	62d7832fff	Fix compiler warning and possible bug	2010-11-13 16:37:42 +00:00
nifi	05d78522d3	Added MAC-layer duplicate message suppression when using 802.15.4 auto ack	2010-11-12 12:53:16 +00:00
adamdunkels	8f745a6ea6	Added a function for obtaining the current parent	2010-11-06 14:32:10 +00:00
adamdunkels	9750eb93bf	Turn off debug messages	2010-11-03 15:41:23 +00:00
adamdunkels	a891a2ffe8	Bugfix: allow ICMPv6 to send packets larger than those whose length fits in one byte. Bugfix by mathieupouillot	2010-11-03 11:56:11 +00:00
adamdunkels	b7df18a96a	Turned off streaming by default to save code space; made guard time a little more conservative	2010-11-02 11:00:08 +00:00
adamdunkels	1b5001b226	Bugfix: out-of-order fragments were not handled correctly. minor style fixes	2010-11-02 10:56:57 +00:00
adamdunkels	5230e64112	Use the new shared ND-packet queue buffers	2010-10-29 05:36:07 +00:00
joxe	9a1f902881	made rank use full resolution when using OF-ETX	2010-10-28 20:39:06 +00:00
adamdunkels	f5031861ac	When IPv6 ND kicks in, the packet that caused the ND can either be dropped or saved in a buffer to be send when the NS reply returns. This commit reimplements the buffer management to avoid having one buffer per neighbor, but instead use a buffer pool from which buffers can be allocated for different neighbors.	2010-10-28 15:42:56 +00:00
adamdunkels	677575fc8c	Rewrote proactive link estimator to be invoked randomly instead of triggered by an empty queue; this makes network bootups because nodes are not synchronized	2010-10-28 15:36:02 +00:00
joxe	932fed8cc7	improved ETX calculation	2010-10-28 08:54:54 +00:00
nifi	25ceab07d2	Update annotation when removing preferred parent.	2010-10-27 12:27:57 +00:00
nifi	d2a3f1f257	We found that the preferred parent should be reset in the rpl_remove_parent function.	2010-10-27 12:20:35 +00:00
nvt-se	d528039f9a	Created a separate function for local repair. Added a statistics structure. Improved the control of malformed packets.	2010-10-27 00:46:40 +00:00
nvt-se	c2c0505402	Increased alpha to 85 in order to get slower changes in the ETX. Put back the start guess to 3.	2010-10-27 00:45:24 +00:00
joxe	43023ab425	made number of transmissions configurable	2010-10-26 13:25:32 +00:00

adamdunkels	3bbd6a00a9	Replace old neighbors according to an LRU policy when a new neighbor needs to be added	2010-10-25 11:58:07 +00:00
adamdunkels	e680276954	ARP fix for multicast transmissions. (Patch by Robert Quattlebaum.)	2010-10-24 22:29:39 +00:00
adamdunkels	a8848517dd	UDP checksum is mandatory with IPv6. (Patch by Robert Quattlebaum.)	2010-10-24 22:28:43 +00:00
adamdunkels	77ecfb0366	Rewrote parts of the retransmission logic so that collect is robust against the situation where the MAC layer will fail to callback after a packet has been transmitted.	2010-10-24 21:08:19 +00:00
adamdunkels	8fa7bf6c31	Always restore the queuebuf to the packetbuf before calling the upper layers. Reduce the waiting time between successive MAC layer retransmissions.	2010-10-24 21:07:00 +00:00
adamdunkels	73f5535754	Made the guard time slightly more conservative - found an occasion where this was needed	2010-10-24 21:06:17 +00:00
adamdunkels	8f8741c7f0	Small style fixes	2010-10-24 21:05:42 +00:00
nvt-se	00a000cca0	Print the rank correctly in the debug output.	2010-10-22 15:40:10 +00:00
nvt-se	86823a84fb	Export fix-point representation of the ETX. Make RPL temporarily use the same representation as before.	2010-10-22 13:50:13 +00:00
joxe	804d23e9f4	made DIS Interval configurable	2010-10-22 13:13:40 +00:00
joxe	e414c8c5a4	added function for retrieving link etx to neighbor	2010-10-22 11:34:24 +00:00
nvt-se	6e28b1d3fb	Reduced ETX_LIMIT in order to avoid overflows. Removed ETX_LOSS_PENALTY and set packet_etx to ETX_LIMIT instead upon packet loss.	2010-10-21 19:46:21 +00:00
adamdunkels	9cb830ed37	Timing bugfix in the waiting period between channel samples to check if the coast is clear before sending a packet.	2010-10-20 22:25:24 +00:00
adamdunkels	3ffcff0656	Added mechanisms for explicit de-synchronization of synchronized neighbors. Added link-layer ACKs. Fixed bugs with MAC-layer interaction. Now seems to work somewhat (didn't work at all before, in some cases), but there are still problems with packet loss.	2010-10-20 15:23:43 +00:00
adamdunkels	5585d72c86	A simple but substantial change: uIP used the htons()/HTONS() macro ... functions for converting between host and network byte order. These names are the de facto standard names for this functionality because of the original BSD TCP/IP implementation. But they cause problems for uIP/Contiki: some platforms define these names themselves (Mac OS, most notably), causing compilation problems for Contiki on those platforms. This commit changes all htons to uip_htons instead. Same goes for htonl, ntohs, and ntohl. All-caps versions as well.	2010-10-19 18:29:03 +00:00
adamdunkels	34cba78ca8	Bugfix: bump advertisements only when a parent changes, not because of an upstream parent change	2010-10-19 07:34:29 +00:00
nifi	e2b4956a7f	Bug fix: release the packet and notify the sender if RDC returned an error	2010-10-14 19:08:39 +00:00
oliverschmidt	2f89e69ff7	Fixed build for platforms which use the default value for QUEUEBUF_NUM.	2010-10-12 19:51:28 +00:00
adamdunkels	020da4e8ba	Added a function for obtaining beacon intervals	2010-10-11 23:44:24 +00:00
adamdunkels	ec716ea62d	Do not reduce transmission interval, unless explicitly told so with the bump flag	2010-10-11 23:43:01 +00:00
adamdunkels	37adf130b4	Rewrite of the congestion logic. A node now report it being congested ... when half the transmission queue is full. When a neighbor is heard to be congested, the rtmetric of that node is inflated to avoid sending more traffic in its direction. Fixed problems with beacon intervals: intervals are now not reduced when a path gets significantly worse, only when they get better.	2010-10-11 23:42:01 +00:00
adamdunkels	d821ba5e22	Added a lifetime for link estimates: if they are too old, they are ... reset so that a new probing period can produce more up-to-date estimates. Added a congestion mechanism whereby a neighbor can be marked as being congested for a period of time, during which the ETX for the neighbor will be artificially inflated.	2010-10-11 23:38:46 +00:00
adamdunkels	5eb4a0fe8d	Rewrote the initial link estimate logic: link estimates are now ... computed only over the actual samples, not over the entire buffer. Also, the initial link estimate is much more conservative now (16 transmissions) to favor links that have been probed, and which therefore are likely to have better ETXs.	2010-10-11 23:34:02 +00:00
adamdunkels	0cabe483c3	Don't call sink recv function for zero-size packets, since these most likely are link estimate probes or keepalive packets. Explicitly set eseqno to zero when opening a new connection.	2010-10-07 15:52:28 +00:00
adamdunkels	ad35c54473	Bugfix: when a node's rtmetric was lower than SIGNIFICANT_RTMETRIC_PARENT_CHANGE, its beacon timers would always be bumped to its lowest value	2010-10-05 20:06:47 +00:00
adamdunkels	52e9a6f1fb	Turned the DRAW_TREE debug flag off by default	2010-10-04 22:36:47 +00:00
adamdunkels	65d640ac53	Several bugfixes to the proactive link estimate maintenance code, which is now enabled by default. Simplified DRAW_TREE code for drawing routing graph in Cooja. Added routing metric penalty to parents that are congested or that drop packets.	2010-10-04 20:27:50 +00:00
adamdunkels	212e73faa6	Removed old netsim code. Added a function for obtaining the packet attributes of a queuebuf packet.	2010-10-04 20:26:01 +00:00
joxe	4f3fc1c404	fixed xmac to use new channel check define name	2010-10-03 22:46:53 +00:00
adamdunkels	ceebd7020a	Bugfix: the return value sometimes was wrong when a collision was detected.	2010-10-03 20:39:24 +00:00
adamdunkels	ae88ed04f1	Moved the definition of the channel check rate used by the radio duty ... cycling layer. This definition was previously held in net/mac/mac.h, with the name MAC_CONF_CHANNEL_CHECK_RATE. But since the rate is used by the radio duty cycling layer, it makes more sense to change its name to reflect this. Also, the configuration option should be tied to the netstack configuration instead. So the new configuration option is called NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE.	2010-10-03 20:37:32 +00:00
adamdunkels	40583fe112	Removed the polite announcement code, since it was not used, and enabled the broadcast announcement code by default. Increased the default intervals for broadcast announcements.	2010-10-03 20:10:22 +00:00
adamdunkels	605392522f	Bugfixes and improvements: rtmetrics are now 16-bit clean. Added experimental feature that proactively probes neighbors that have not yet been tried out, in order to get an initial ETX for them.	2010-10-03 20:08:44 +00:00

adamdunkels	eed22a6f3c	A number of changes to the collect code: ... * Added an optional "keep alive" mechanism whereby an idle network is periodically probed by dummy packets to maintain a recent quality metric when there is no traffic. * Bugfix in when new routing metrics should be advertised * Rewrote the ACK logic so that a queuebuf is not allocated for each ack, only for those acks generated by the sink node. * Updated the wrap-around logic for sequence numbers: when a sequence number wraps, it won't go back to 0. Instead, it wraps to 128. This allows us to understand when a node has rebooted: when its seqno is < 128, it has recently rebooted.	2010-09-22 22:08:08 +00:00

oliverschmidt	e5665fb968	The recent change turning uip_buf from an array to a pointer seems a quite heavyweight way to have the uip_buf alligned to a 32-bit boundary. Contiki is - still - supposed to be portable across a wide range of toolchains - therefore it i.e. intentionally doesn't use C99 features. From that perspective it seems questionable if all toolchains are able to optimize away the overhead imposed by an "unnecessary" indirection to access uip_buf - and uIP consists mostly of accesses to uip_buf. Even if the future is supposed to bring support for multiple uip_bufs which would turn the uip_buf pointer from a mere workaround to an neceesary element on can still presume that there will be targets with resources limited in a way prohibiting the use of several uip_bufs. So at least for those targets will still be a usecase for a "plain", not indirected uip_buf. ... Therefore it seems reasonable to allow to stay with the "plain" uip_buf at compile-time.	2010-05-08 07:23:55 +00:00

adamdunkels	7d6ff0289e	Fiddled more with the timing: the phase seems stable now at least. Still bugs left though...	2010-04-04 12:28:29 +00:00
adamdunkels	be117afe04	After a lot of tweaking and twiddling with the timing of the ContikiMAC code and the mechanisms in the CC2420 driver, things seem to work somewhat stable now - knock on wood!	2010-04-04 07:49:30 +00:00
adamdunkels	83eaa70f03	Added pending flag	2010-04-03 13:34:20 +00:00
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	a8d8b6d31d	Improved parent management: parent neighbor is retained until a better neighbor is found (with 1 ETX less than parent). Don't drop parent neighbors when loop is detected (loops are transient anyway).	2010-04-01 10:45:21 +00:00
adamdunkels	d7457bc340	Improved parent management: parent neighbor is retained until a better neighbor is found (with 1 ETX less than parent). Don't drop parent neighbors when loop is detected (loops are transient anyway).	2010-04-01 10:03:19 +00:00
adamdunkels	add426de4b	Bugfixed stream mode: node listens 100% for 0.5 seconds in stream mode. Naming change: is_listening changed is_snooping.	2010-04-01 10:02:04 +00:00

nifi	9508d2c4d7	* Added configurable default number of transmissions for CSMA to use when not specified using packetbuf attributes (CSMA_CONF_MAX_MAC_TRANSMISSIONS). ... * Renamed packetbuf attribute PACKETBUF_ATTR_MAX_MAC_REXMIT to PACKETBUF_ATTR_MAX_MAC_TRANSMISSIONS where value 0 (attribute not set) means that default number of transmissions should be used.	2010-03-26 12:29:29 +00:00

adamdunkels	a4f9e62295	Added a parameter to collect_open() that specifies whether or not the node should be a router for packets, or only an originator of packets. Updated the collect module to the new annoucement API.	2010-03-25 08:51:07 +00:00
adamdunkels	2559e27414	API change to the announcement module: an annoucement can now be registered without a value. Such announcements are never transmitted to neighbors, until the announcement's value is set.	2010-03-25 08:49:56 +00:00
adamdunkels	4d68bdf74b	Bugfix and addition by Dogan Yazar: psock_readbuf() shouldn't wait for a full buffer (which might never happen); a new function for sending strings that batches data and sends full buffers instead of individual strings.	2010-03-24 21:03:32 +00:00
nifi	c623616afd	Neighbor state notification also when adding new neighbors	2010-03-24 16:29:45 +00:00

adamdunkels	b1feac5a00	Bugfixes in low-power streaming mode, and re-added support for announcements. These now use the low-power streaming mode so that active listening for announcments have a radio duty cycle of 16% rather than 100%	2010-03-16 18:11:13 +00:00
nifi	6b7ec2d002	removed uip_router	2010-03-16 15:45:20 +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
oliverschmidt	def540e6c0	Avoid newlines in macro expansions as cc65 doesn't support them between the macro name and the open parenthesis of the arguments. ... There were btw other even longer lines with expansions of the same macro already present.	2010-03-14 12:13:54 +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

adamdunkels	7165a3866f	Significant rework of the Contiki data collection protocol: ... * the new version makes use of MAC-layer feedback so that bad paths can be identified quicker and then avoided. * the new code uses transport layer ACKs that contain feedback from the collect protocol: when a packet cannot be forwarded due to lack of resources, the ACK contains a flag that indicates that the packet could not be forwarded. ACKs also contain the routing metric of the sender, which improves agility in face of rapid path changes. * loop detection and management has been improved: with higher path metric agility, the system is more prone to short-lived routing loops. Instead of dropping looping packets, the new version adjusts the routing metric for the routes that exhibit loops so that the risk for future loops is reduced. * make use of packet attributes to inform the MAC layer of how many times packets should be retransmitted.	2010-02-28 09:18:01 +00:00
adamdunkels	b6b4941871	Made the number of MAC-layer retransmissions configurable on a per-packet basis, via a packet attribute	2010-02-28 08:35:16 +00:00
adamdunkels	ed88f487c8	Improved detection of link-layer ACKs; increased the time ContikiMAC waits when it has detected a link-layer ACK; increased the number of silence periods required to detect a CCA false positive	2010-02-28 08:33:21 +00:00
adamdunkels	fa1a96636e	Bugfix: the compile-time check for UIP_LLADDR_LEN previously generated a run-time error, when it should have generated a compile-time error	2010-02-28 08:30:39 +00:00
adamdunkels	ba0e50a7b7	Set the default number of MAC layer retransmissions for IPv6 packets to 2	2010-02-28 08:29:42 +00:00

nifi	b50d47fb80	added missing function in sicslowmac_driver	2010-02-23 22:45:11 +00:00
nifi	1cfcc8a73a	Removed the combined name of CSMA and NETSTACK_RDC. The name of NETSTACK_RDC can be accessed separately if needed.	2010-02-23 20:42:45 +00:00
nifi	c20047f657	Changed the network stack to use different structures for the different layers (network_driver, mac_driver, rdc_driver, radio_driver). This helps to avoid incorrect configuration.	2010-02-23 20:09:11 +00:00
adamdunkels	bb62749de7	Made debug printfs optional	2010-02-23 18:49:58 +00:00
adamdunkels	0ab2ba433f	Bugfix: the wrong callback pointer was passed to higher layers.	2010-02-23 18:49:45 +00:00
adamdunkels	ed52586e18	Rework of parts of the ContikiMAC code based on input from experimental results. When channel check is triggered because of a false positive, the new version checks the radio several times to make sure that there really is an incoming packet. Otherwise, the radio is switched off. Cleaned up and removed old unused code. Added a few temporary debugging mechanisms and functions.	2010-02-23 18:49:05 +00:00
adamdunkels	ca0417a923	Added the MAC layer callback functionality so that the Rime network layer gets information from the MAC about the status of sent packets: were they successfully transmitted, or was there a collisions? How many retries were there?	2010-02-23 18:38:05 +00:00
adamdunkels	f10eedab3e	Added debug printout	2010-02-23 18:37:15 +00:00
adamdunkels	2d13fecea7	Improved backoff management: timer is now doubled on every transmission, until the using module calls the neighbor_discovery_start() function again. Don't cancel the transmission even if a lower value arrives (this fixes a problem with multi-hop ETX propagaion).	2010-02-23 18:36:50 +00:00
adamdunkels	0eade2886c	Better loop handling: when a loop is detected, the neighbor to which the packet was originally sent gets an inflated ETX; made sure that collect without announcments work; increased timeouts, to work nicer in larger networks	2010-02-23 18:35:23 +00:00
adamdunkels	a4d9d6651b	Added the option to specify the old value to observers so that they can determine if the announcement should be sent out quicklier than otherwise	2010-02-23 18:32:44 +00:00
adamdunkels	b746b7fc06	Reworked the Rime/Chameleon interface so that packets now always hit Rime before Chameleon. Chameleon is now only called by Rime. This makes packet sniffing easier, and allows for sniffing packets after their header has been processed by Chameleon, thereby making per-packet power profiling much easier to implement	2010-02-23 18:29:53 +00:00

adamdunkels	e34eb54960	A work-in-progress rework of the Contiki MAC and radio layers. The ... main ideas are: * Separates the Contiki low-layer network stack into four layers: network (e.g. sicslowpan / rime), Medium Access Control MAC (e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and radio (e.g. cc2420). * Introduces a new way to configure the network stack. Four #defines that specify what mechanism/protocol/driver to use at the four layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC, NETSTACK_CONF_RADIO. * Adds a callback mechanism to inform the MAC and network layers about the fate of a transmitted packet: if the packet was not possible to transmit, the cause of the failure is reported, and if the packets was successfully transmitted, the number of tries before it was finally transmitted is reported. * NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc, which can be used when MAC and RDC functionality is not needed. * Extends the radio API with three new functions that enable more efficient radio duty cycling protocols: channel check, pending packet, and receiving packet. * New initialization mechanism, which takes advantage of the NETSTACK #defines.	2010-02-18 21:48:39 +00:00
adamdunkels	f8c804e28b	ntikiMAC: a new radio duty cycling mechanism that uses a combination ... of link-layer and MAC-layer mechanisms to achieve a very low power consumption: during idle listening the radio is switched off between 99.2% and 99.6% of the time. One unicast transmission typically adds between 0.07% and 1.2% additional radio time, depending on packet size. ContikiMAC uses the standard IEEE 802.15.4 message format and adds no additional headers. ContikiMAC is simple: it uses periodic two-shot channel sampling during idle listening to keep the radio on-time down. Transmissions are done with repeated transmissions until a link-layer ACK is received.	2010-02-18 21:26:15 +00:00

adamdunkels	d67d1f7340	Major bugfix, found by Raimondas Sasnauskas: the TCP periodic timer was not started when a new connection request arrived.

adamdunkels	671216c558	No need to clear the headers now that we explicitly save a queuebuf when sending fragments	2010-02-06 17:07:43 +00:00
adamdunkels	b6647b5630	Turns out that with cxmac, clearing the header after sending a packet is not enough to make fragmentation work. Instead, we allocate a queuebuf and restore the packet after from the queuebuf after sending it.	2010-02-06 09:42:49 +00:00
adamdunkels	494e692d0b	Bugfix: clear the header after sending a packet solves a problem with fragmentation; also prod the watchdog since fragment transmissions can take a long time with some low-power MAC protocol	2010-02-06 07:49:58 +00:00

adamdunkels	1a13d25d33	Revised version of the X-MAC implementation that uses a ctimer instead ... of an rtimer for the periodic radio duty cycling. The benefit of this implementation is that it leaves an rtimer free for user tasks. The drawback is a slightly higher idle power consumption.

adamdunkels	1752b53f74	Refresh routes when a packet is received. Set a conservatively low route timeout (10 seconds).	2009-05-04 11:24:04 +00:00
adamdunkels	c83c5c4c55	Removed automatic refresh of routes from the route_lookup() function and moved it into an explicit route_refresh() function. The previous behaviour was dangerous, since it meant that even bad routes that someone was looking for were considered fresh. Now such routes time out if they are not explictily refreshed (e.g., on a packet reception)	2009-05-04 11:23:30 +00:00
adamdunkels	f5a57a4e54	Fixes by Ward Van Heddeghem (reapplied from versioin 1.24)	2009-04-30 20:21:06 +00:00
adamdunkels	e70cf0c7c6	Rewrite of the collect module. The new version uses a packet queue for outgoing and forwarded packets so that more than one packet can be forwarded at the same time. The new version uses the packetqueue module to maintain the packet queue.	2009-04-29 20:48:57 +00:00
adamdunkels	c489b1118d	New module: packetqueue. The packetqueue module maintains packet queues for other modules.	2009-04-29 20:47:30 +00:00

adamdunkels	c02a82ac41	Tag outgoing TCP packets with the ERELIABLE attribute so that an underlying power-saving MAC protocol can treat them differently, because it knows that an ACK might be arriving soon	2009-04-29 11:40:33 +00:00
adamdunkels	c9df0ab123	Bugfix in debug message printout	2009-04-28 14:01:46 +00:00
adamdunkels	81ef83b856	Added option to wait randomly before sending a packet. A few code cleanups. Avoid switching radio off when sending a packet with end-to-end acks, because an ACK may arrive shortly after the transmission.	2009-04-28 14:00:53 +00:00
adamdunkels	fdd05f5c71	Bugfix: psock send should use PT_WAIT_UNTIL() not PT_YIELD_UNTIL(). This improves TCP throughput by 100x under minimal-net	2009-04-28 13:52:04 +00:00

adamdunkels	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
adamdunkels	65eb5fd4e8	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 21:58:20 +00:00

adamdunkels	9816f49fe6	Changed listen and transmit energy attributes so that they are named _TIME rather than _ENERGY, to indicate that they contain the time during which the radio was switched on and not the energy	2009-03-02 22:00:41 +00:00
adamdunkels	78591a003f	Minor documentation update	2009-03-02 21:56:16 +00:00

adamdunkels	7010eb84b8	Added support for communication power accounting. Energy is attributed to idle listening when the radio is switched off. Enegrgy is attributed to an incoming packet when it is received. Energy is attributed to an outgoing packet when it is transmitted.	2009-03-01 20:37:16 +00:00
adamdunkels	aa2f7a3399	Made polite announcement times configurable, added missing right-brace	2009-03-01 10:43:57 +00:00

adamdunkels	e6907a1d8b	Include random.h	2009-02-20 21:22:39 +00:00
adamdunkels	4ec5167276	Rewrote the tcpip_output() and tcpip_set_outputfunc() so that the latter is a proper function (which simplifies debugging) and so that tcpip_output() checks if the output callback function is NULL before calling it	2009-02-20 21:21:56 +00:00
julienabeille	10deaa6fc6	Removed CLOCK_SECOND from stimers in uIPv6, stimers are already in seconds	2009-02-20 07:59:35 +00:00

adamdunkels	aaa8c9d2c9	Construct the X-MAC header on the stack instead of directly in the packet header, because the packet header may be misaligned. A bit of cleanup in the code too.	2009-02-15 22:05:06 +00:00
adamdunkels	e4b1ff461e	Added MAC-layer announcement beacons to X-MAC. Configuratble through XMAC_CONF_ANNOUNCEMENTS	2009-02-14 20:35:03 +00:00
adamdunkels	585620c102	Reverted the recent change from random_rand() to rand(). It turned out that ... since libc rand() returns a signed int, there were frequently problems with timer values wrapping. By reverting to random_rand(), we can provide a random generator that returns an unsigned and the timer problems are solved.	2009-02-11 11:08:53 +00:00
adamdunkels	9d75781a78	Added packet attributes for energy spent on a packet (RIMEBUF_ATTR_LISTEN_ENERGY and RIMEBUF_ATTR_TRANSMIT_ENERGY)	2009-02-10 23:51:12 +00:00
adamdunkels	b15198b9a8	Bugfix: the Chameleon header parser modules should not clear the packet attributes, because the MAC or radio layers may have added attributes already	2009-02-10 23:49:58 +00:00
adamdunkels	e1ef13dad6	Reduced the size of the packet cache from four to two to avoid falseley dismissing fresh packets (the header field that hold sequence numbers is only two bits wide, hence all sequence numbers fits in a four-entry cache...)	2009-02-10 00:44:50 +00:00
adamdunkels	6c95bd895a	Added default initialization of polite announcements. Not sure where the best place for this is, but this at least allow us to start experimenting with this.	2009-02-09 22:05:33 +00:00
adamdunkels	3efb83c338	Added announcement includes	2009-02-09 21:09:42 +00:00
adamdunkels	0de445e035	Initialize the announcement module	2009-02-09 21:08:12 +00:00
adamdunkels	3670ef2f44	Rewrote the collect module so that it uses the announcement module rather than the neighbor-discovery module. This makes it possible to implement other annoumcement back-ends than the traditional broadcast-based neighbor discovery	2009-02-09 20:58:25 +00:00
adamdunkels	dd9ffd87c4	Added missing #include announcement.h	2009-02-08 20:14:18 +00:00

adamdunkels	4b71003c2f	Changed from random_rand() to rand() for better pseudo randomness	2009-02-07 18:43:45 +00:00
adamdunkels	752291f450	Changed from random_rand() to rand() function for (pseudo) random numbers because random_rand() does not work that well	2009-02-07 16:16:31 +00:00
adamdunkels	91e8487032	Added Doxygen documentation	2009-02-07 16:15:37 +00:00
adamdunkels	be846d8c90	A new experimental network primitive called an 'announcement'. An ... announcement is an (ID, value) tuple that is disseminated to local area neighbors. An application or protocol can explicitly listen to announcements from neighbors. When an announcement is heard, a callback is invoked. Announcements can be used for a variety of network mechanisms such as neighbor discovery, node-level service discovery, or routing metric dissemination. Application programs and protocols register announcements with the announcement module. An announcement back-end, implemented by the system, takes care of sending out announcements over the radio, as well as collecting announcements heard from neighbors.	2009-02-05 19:32:01 +00:00
fros4943	4f1a9d3c75	bugfix: stopping timeout timer when we receive route reply (still limited to only one active discovery)	2009-01-21 14:29:24 +00:00

c_oflynn	17790ce46a	Bug fix by David Kopf - sicslowpan timeout was always set at 20 seconds, this greatly improves performance!!	2008-12-02 22:04:16 +00:00
adamdunkels	50b1e60621	Rewrote the rimeaddr_copy() loop to use the ->u8 field instead of the ->u16 field (which now finally is removed)	2008-11-30 18:26:57 +00:00
adamdunkels	6951d9d582	Removed the unused ->u16 field (it was there only as a convenience/laziness access method during the initial development of the Rime stack, but has caused problems when being there)	2008-11-30 18:26:06 +00:00
oliverschmidt	7cf3165155	Replaced NETSIM macro with general (and now actually working) solution in Makefile.include.	2008-11-17 22:52:10 +00:00
fros4943	e42d572f81	updated for latest mac driver structure	2008-11-12 12:42:41 +00:00
zhitao	229d60d691	Neighbor ETX should accumulate over retransmission timeouts; ... Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.	2008-11-12 10:47:17 +00:00
oliverschmidt	75ffd0640c	Inform user about (most likely unintentional) call of dummy_tcpip_output_function.	2008-11-10 21:00:53 +00:00
adamdunkels	3b283a5ff3	Added dummy function so that tcpip_output() always is defined, even if tcpip_set_outputfunc() never has been called. This fixes a bug with programs attempting to use the network when compiled for the native platform.	2008-11-09 12:29:24 +00:00
adamdunkels	5243d58ac5	Added logic for announcing that a network has a gateway to the outside world (with the function uip_over_mesh_make_announced_gateway()). The announced gateway sends a trickle message to the network, containing the address of the gateway. Other nodes will then know that packets destined to the outside world should go through the gateway node.	2008-11-09 12:20:56 +00:00
adamdunkels	8851a6359a	Remove unguarded printf()	2008-11-09 12:16:05 +00:00

adamdunkels	d73124cc5e	Bugfix: there was a problem with TCP segments not being properly retransmitted for protosockets-based applications. Cleaning up the logic around acknowledgements and retransmissions fixed the bugs pertaining to retransmissions of lost packets. This bugfix affects both the telnet server and the web server (which now work as expected wrt packet loss).	2008-10-31 18:10:24 +00:00
adamdunkels	f623b81d59	Temporarily out-commented the problematic code and added a comment that describes the problem	2008-10-17 14:40:16 +00:00

blakelev	99f6932cdf	Removed one line to prevent the default router from being removed ... prematurely. This timer should not time out, but it does.	2008-10-15 23:29:38 +00:00
adamdunkels	adc57729c3	struct uip_udp_conn should be declared even if UIP_UDP is zero (it does not add any extra code)	2008-10-15 08:56:44 +00:00
adamdunkels	e931260603	Added more curly brackets to ensure ANSI C compliance when UIP_TCP is defined;	2008-10-15 08:52:30 +00:00

adamdunkels	412facb831	This is an initial commit of an implementation of the Chameleon ... architecture for the Rime stack for Contiki. The Chameleon architecture separates the header processing from the Rime protocol logic. Instead of having each protocol create its own part of the packet header, protocols use packet attributes. Before sending a packet, a special Chameleon header processing module creates a packet header from the packet attributes. The same Chameleon module parses incoming packets and creates packet attributes from the header. The details are in our SenSys 2007 paper: Adam Dunkels, Fredrik Osterlind, Zhitao He. An Adaptive Communication Architecture for Wireless Sensor Networks. In Proceedings of the Fifth ACM Conference on Networked Embedded Sensor Systems (SenSys 2007), Sydney, Australia, November 2007. http://www.sics.se/~adam/dunkels07adaptive.pdf This is a rewrite of the code that was developed for the paper.	2008-02-25 02:14:34 +00:00
