Adam Dunkels 09f30e875d Bugfix: when a CSMA callback is received, we should remove the packet 
that was transmitted and not just the first packet that happens to be on
the output queue.

Adam Dunkels 7742b05d8c Major bugfix: when nullrdc is asked to send a list of packets, send the list of packets and not just the first packet - this is essential for retransmissions of fragmented IP packets to work 2013-03-18 13:35:29 +01:00
Adam Dunkels 4efd570cf9 Minor bugfix: explicitly cast pointer argument in debug printf 2013-03-18 11:22:05 +01:00
Adam Dunkels f2fbb4b49d Defensive programming: make sure that we don't fail completely if we get a callback for a NULL pointer 2013-03-18 11:22:04 +01:00
Adam Dunkels 82b755c017 Bugfix: keep track of receiver being awake as a local variable rather than a global, as it may have changed between invokations 2013-03-18 11:22:02 +01:00
Adam Dunkels 0670a8e1e2 Minor code style fixes to the contikimac and nullrdc code 2013-03-18 11:22:01 +01:00
Adam Dunkels 5993595a8f A number of updates to nullrdc 
* add a few rimestats to keep track of sent and received acks
* made a number of configuration options possible to override (ack timing)
* added the logic for sending 802.15.4 link layer ack packets, despite not being able to guarentee the 802.15.4 MAC timing
* increased the number of sequence numbers to keep track of for duplicate filtering

Adam Dunkels 4541d3e85b Let the framer functions use ints instead of uint8_t to make them more generic 2013-03-18 11:19:18 +01:00
Robert Quattlebaum c0a693672c core/net: Added support for "bridge mode". 
"Bridge mode" allows devices to more easily send 802.15.4 packets as if
they were a different device. It also turns off any packet filtering
that may be implemented at layer 2. It works by allowing
`PACKETBUF_ADDR_SENDER` to be set earlier in the stack.

This is useful for implementing 6LoWPAN-ethernet bridges.

Enabled via setting `NETSTACK_CONF_BRIDGE_MODE` to 1. Disabled by
default.
 2013-03-10 14:45:15 -07:00
Adam Dunkels cb7842bd16 Added support for encryption and decryption of the packetbuf if macros 
NETSTACK_ENCRYPT and NETSTACK_DECRYPT are defined. Those are intended
to be called as functions NETSTACK_ENCRYPT() and NETSTACK_DECRYPT() to
encrypt and decrypt the packetbuf, respectively. If needed, an
initialization function by the name NETSTACK_ENCRYPTION_INIT() can
also be defined.

Adam Dunkels 6ee1f72486 Removed old unused TDMA-based MAC and RDC code 2012-11-20 20:48:34 +01:00
Adam Dunkels ec8c7e9be0 Cleanup of the node-id.h files. The node-id.h file contains 
declarations of functions for setting and getting a node ID number, a
functionality that exists on many platforms. Since this functionality
was not considered part of the Contiki core, each platform defined its
own node-id.h file. This commit attempts to clean this up by
collecting the node-id.h into a core/sys/node-id.h file that replaces
the old node-id.h files from the platform directories.

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
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 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 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
adamdunkels af21afa750 Make sure that the cycle timing is exact 2010-12-10 13:36:06 +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
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 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
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
nifi 05d78522d3 Added MAC-layer duplicate message suppression when using 802.15.4 auto ack 2010-11-12 12:53:16 +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 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
nifi e2b4956a7f Bug fix: release the packet and notify the sender if RDC returned an error 2010-10-14 19:08:39 +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 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.

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 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 9c58768b59 Extend packet size after creating 802.15.4 header; prepare radio chip with packet before waiting for neighbor phase to make phase wait time deterministic 2010-03-29 21:51:36 +00:00
adamdunkels b4b7e942b6 Back off a guard time for every non-ack packet 2010-03-29 21:50:01 +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.

adamdunkels 49009e9cbd Extend the length of announcement packets if they are too short 2010-03-19 13:24:58 +00:00
adamdunkels 115b3a7c5c Minor timing bugfix: the time between channel checks should not include the time required for the channel check itself 2010-03-17 18:24:06 +00:00
adamdunkels efeb9944fa Increase the required non-activity periods before turning off the radio; remove the strict phase requirement (which messes up things with low-power streaming) 2010-03-17 16:35:52 +00:00
adamdunkels 9be1a65211 Don't set the RELIABLE flag on incoming packets with the ack requested flag set, since it is set on most packets even if they aren't reliable 2010-03-16 18:11:58 +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 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.

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.
