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
adamdunkels d267b5ca94 Re-added timestamp support for outbound packets that was removed when switching to the new radio API 2010-12-16 22:40:52 +00:00
adamdunkels 417c7f8c70 Added parenthesis around addresses to allow expressions as arguments 2010-12-16 22:39:50 +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

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
adamdunkels 433d42e170 Bugfix: if the cc2420_cca() function wasn't able to turn on the radio properly, it should turn it off again if it was off before. 2010-12-05 00:14:24 +00:00
dak664 f34e5ec798 Convert implicit printf to PRINTF 2010-12-04 21:06:04 +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.

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
nvt-se 1168703506 Minor clarifications in the code and comments. Integrated atches from Frederic Sureau: 1. copy_buf is now an ordinary char pointer. 2. Read directly from a file that is not modified. This reduces the code size when COFFEE_MICRO_LOGS is set to 0. 3. Update the file end value each time it is changed in case a log merge operation occurs later. 4. Avoid possible alignment problem in reading from the dummy_space area when calling cfs_readdir. 2010-11-11 13:08:23 +00:00
adamdunkels 8f745a6ea6 Added a function for obtaining the current parent 2010-11-06 14:32:10 +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

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
adamdunkels fd4c0e64aa Removed old unused files rand.[ch]. By default, Contiki uses the libc implementations of the rand() and srand() functions. 2010-10-24 21:02:23 +00:00
nvt-se 00a000cca0 Print the rank correctly in the debug output. 2010-10-22 15:40:10 +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 06123fefe2 Defensive programming: make sure that a process is actually running before we try to kill it. 2010-10-20 22:24:46 +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 d0579c8a81 Cleaned up the collect neighbor management code 2010-10-03 20:07:10 +00:00
adamdunkels b23a364397 rtmetric values should always be computed as 16-bit values 2010-10-03 20:06:25 +00:00
nvt-se 909569f834 Must check if load_file succeeded 2010-10-01 20:14:14 +00:00
adamdunkels 32ba90ea4c Bugfix: make sure that neighbor exists before attempting to update tx 
count.
 2010-09-28 06:53:02 +00:00
joxe 77c5187a2e fixed bug where context is null but still referenced 2010-09-23 19:57:50 +00:00
joxe 494d2a3073 only compare with global addresses when selecting source for a specific destination 2010-09-23 18:17:27 +00:00
nifi e242fb28bf Reverted radio API change in CC2420 (not yet fully integrated with Contiki core) 2010-09-23 08:26:06 +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
adamdunkels 2cae71e89b Added a function for obtaining the link estimate and rtmetric for a neighbor 2010-09-22 22:04:55 +00:00

dak664 b9a9e7695d Add option to remove process name strings to save RAM 2010-09-14 18:55:04 +00:00
adamdunkels 18e31f33b9 Minor tweaks. Removed debug output from CVS. 2010-09-14 06:48:36 +00:00
nifi 095f700b63 Moved down inclusion of rtimer-arch.h to allow rtimer_clock_t to be used in rtimer-arch.h 2010-09-13 20:46:02 +00:00
adamdunkels eb58968459 Added a timer to each phase structure that keeps track of for how long 
a particular receiver has not ACKed packets. After some time
(currently 16 seconds), the sender will begin sending full strobe
periods again.
 2010-09-13 13:39:05 +00:00
adamdunkels 3ae774c91a Added a way to for specifying lists as parts of structs. These lists 
must be initialized with a special LIST_STRUCT_INIT() call before
using.
 2010-09-13 13:31:00 +00:00
adamdunkels 591766e663 Significant improvements to the Collect protocol: 
* Loop detection and untangling. Now uses in-band loop detection that
  works.

* Link quality estimation. Now starts with a conservative /
  pessimistic estimate for new links.

* Retransmissions. MAC layer and network layer retransmissions are now
  decoupled.

* Loss handling. Deals better with losses now.

* Concurrent applications. Each connection now maintains its own
  neighbor table with separated cost to sink estimates for each
  connection.

oliverschmidt a0b8927777 Allow to exit the process owning the foreground window by pressing ctrl-c. This is especially useful if there's no closebutton on the window frames (or no windows at all). 2010-09-09 20:21:26 +00:00

oliverschmidt 89f6235c13 Using wherex() to determine the length of the string printed with cputsn() fails if the right edge of the screen was reached as wherex() then returns 0. 
Therefore we rather count the chars actually printed in cputsn() and return that value thus avoiding usage of wherex() in those scenarios altogether.

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.

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 a637ddaf4e Flush the rxfifo when turning off the radio instead of when turning it on. This seems to fix a bug that was seen in mspsim and seemed to appear on real hardware too. 2010-04-03 16:01:00 +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

 2010-03-31 09:38:42 +00:00
adamdunkels bcfa80102d Had previously not included the waiting time that the CC2420 introduces when sending a packet. Also increased the smallest packet size, just to be on the safe side. 2010-03-30 23:01:32 +00:00
adamdunkels 4d5f112960 New return value for invidating a link-layer collision 2010-03-30 23:00:22 +00:00
adamdunkels 5e7f99a2c0 Reverted the removal of the code that checked the FIFOP pin before reading a packet - checking FIFOP is the correct way to do it. Also added TXONCCA for now, including new radio.h return values to indicate a link-layer collision. 2010-03-30 23:00:05 +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

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
adamdunkels 67b0170a43 Bugfix: don't care about FIFOP when reading a packet; if the radio rx had been turned off before a packet was read, FIFOP would be zero and the packet would be trashed 2010-03-16 18:10:09 +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
adamdunkels 0035a70537 Reworked the locking code, which seems to fix a few bugs caused by the interaction with contikimac. Contikimac performs a CCA check in a preempting rtimer, which requires underlying code to properly call the GET_LOCK() macro. This fix seems to solve most problems, but there may be others left. 2010-03-14 22:45:20 +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.
