adamdunkels 50e1452564 Ugly workaround for internal error in mspgcc when applying the >= operator to two 32-bit values 2010-02-23 18:40:08 +00:00
adamdunkels 0c4c88ae66 Improved per-packet power profiling: if a packet is retransmitted, the new energy is added to the old energy so that it is possible to measure the full energy for all transmissions of the packet 2010-02-23 18:39:00 +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 d8cce42d28 Set the default radio driver to nullradio 2010-02-23 18:28:04 +00:00
adamdunkels 47578806b5 Removed semicolon from #define to allow the semicolon to be placed naturally after the macro is used 2010-02-23 18:27:04 +00:00
adamdunkels 4b04fdd328 Minor style fix 2010-02-23 18:26:26 +00:00
adamdunkels 1ee32c3074 Removed non-functional time synchronization code; added some experimental code for CCA checks (enabled CCA mode 1, a temporary development function for setting the CCA threshold); enable the possibility to switch off radio even if a packet is currently arriving 2010-02-23 18:24:49 +00:00
adamdunkels 5292005962 A null radio driver that does not do anything - useful in the native port and as a template for new radio drivers 2010-02-23 18:18:53 +00:00
adamdunkels 0b2b7bcdba Removed inadvertedly left-over include file 2010-02-18 23:52:34 +00:00
adamdunkels 5cf3b83733 Common initialization code for the netstack 2010-02-18 23:15:26 +00:00
adamdunkels a2664054c5 Always include netstack.h 2010-02-18 23:09:30 +00:00
adamdunkels f49ebfe1c4 Temporarily disabled rime route udp because it breaks with newest MAC interfaces 2010-02-18 21:53:08 +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.

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 f5c48751b5 Reworked 802.15.4 header creation and parsing so that it works regardless of the size of the rimeaddr_t typedef 2010-02-18 21:00:28 +00:00
adamdunkels 2fbf21b2b3 Refactored the phase optimization functionality into a separate module 2010-02-18 20:58:59 +00:00

adamdunkels 9bb149ca13 Bugfix by Raimondas Sasnauskas: TCP SYN duplicate receptions in the SYN_RCVD state was not correctly handled 2010-02-15 18:03:07 +00:00
adamdunkels d67d1f7340 Major bugfix, found by Raimondas Sasnauskas: the TCP periodic timer was not started when a new connection request arrived. If there were no other active TCP connections, this means that the SYNACK would never be retransmitted, potentially leading to a forever stale TCP connection. 2010-02-09 12:58:53 +00:00
adamdunkels 4a522c96dd Added debugging statements for packet drops 2010-02-08 21:59:49 +00:00
adamdunkels 2b6a651233 Added missing include, made debug statement more explicit 2010-02-08 21:59:21 +00:00
adamdunkels 2eba08e8f6 Made queuebuf statistics configurable, and off by default 2010-02-08 21:10:32 +00:00
nvt-se f4d19560fc Fixed a performance problem by not allowing GC while doing merges of files and micro logs. 2010-02-08 14:08:14 +00:00
oliverschmidt c284092a53 - Set cursor in ctk_draw_init() to top left corner as it is called for re-initialization on Contiki exit. 2010-02-07 21:43:03 +00:00
oliverschmidt 1d1f3a23af - No need for textcolor() before cclear(). 
- Set textcolor() in ctk_draw_init() to some reasonable value as it is called for re-initialization on Contiki exit.
 2010-02-07 21:38:01 +00:00
adamdunkels b98f7d891f Bugfix: added missing queuebuf allocation 2010-02-06 20:50:24 +00:00
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 a68b4c40c4 Added a function to clear only the header part of the packetbuf 2010-02-06 07:48:52 +00:00
oliverschmidt e88d209214 Adjusted process name to title case. 2010-02-05 19:13:05 +00:00

oliverschmidt 5e66abda50 Initialize lastport in all cases it is defined. 2010-02-04 21:33:51 +00:00
adamdunkels d8b0625e21 Bugfix: lastport must be defines both when UIP_ACTIVE_OPEN or UIP_UDP are defined (thanks Oliver!) 2010-02-04 21:14:45 +00:00
adamdunkels 7bcb106fa9 Disable the stream mode for TCP packets since it does not seem to work reliably with cxmac 2010-02-04 18:57:33 +00:00
adamdunkels 13f6673d04 Bugfix: drop incoming TCP and UDP packets where port numbers are zero 2010-02-04 11:17:42 +00:00
adamdunkels d7b7b05d0e Moved the neigbor_init() call to the collect module, since it is the only one that currently uses it 2010-02-03 20:38:33 +00:00
adamdunkels 75e1c0c8c7 Include contiki-conf.h to let the MAC channel check rate be configurable 2010-02-03 16:45:12 +00:00
adamdunkels 06d17c7e1c Remove unused rtimer code 2010-02-03 16:44:43 +00:00
adamdunkels 4bffd277f5 Don't set the stream bit on outgoing TCP packets for now - it doesn't seem to play well with IPv6 and X-MAC 2010-02-03 16:44:19 +00:00
adamdunkels 36db5eb70b Added debug printout 2010-02-03 01:18:24 +00:00
adamdunkels e419eb3cc5 Retransmit packet if it didn't receive a MAC layer ack 2010-02-03 01:17:54 +00:00
adamdunkels d68af249ec Added a MAC layer return value that informs the caller that a packet did not receive a MAC layer acknowledgement 2010-02-03 01:17:32 +00:00
adamdunkels 4bc4f033e8 Increase the trickle resend interval for router advertisements 2010-02-03 01:13:17 +00:00
adamdunkels 181213124b Added a configuration option for setting the MAC channel check rate (which must be a power of two). The configuration is independent of the MAC protocol. 2010-02-02 23:28:58 +00:00
adamdunkels f66cd6d44e Increased the forwarding queue to six packets to improve collection robustness 2010-02-02 21:44:05 +00:00

adamdunkels 0db31db624 Moved declarations to the start of each function 2010-02-02 21:09:06 +00:00
adamdunkels fcf60e9260 Removed the csma_init declaration in the mac_driver struct since it isn't needed and it breaks sdcc 2010-02-02 20:45:58 +00:00
adamdunkels cc2be0f111 Remove compiler warnings 2010-02-02 16:33:07 +00:00
adamdunkels 88c661b0c2 Rewrote the netif time code so that is avoids the use of floating point numbers; some code style fixes 2010-02-02 16:32:03 +00:00
oliverschmidt 3f142f0718 Convert '@' correctly from PETSCII to ASCII - by leaving it alone. 2010-01-31 23:46:19 +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. This new version
is based on the current rtimer-based X-MAC.
 2010-01-31 18:44:23 +00:00
adamdunkels e4168db633 Bugfix: deallocate queuebuf only if there was no collision 2010-01-31 13:55:36 +00:00

adamdunkels 71ffde578e Moved route_init() into mesh instead of the generic rime initialiation 2010-01-25 13:54:26 +00:00
adamdunkels 423e37f426 Added parameter to ipolite that specifies how many dups that are acceptable, before suppressing one's own packet 2010-01-25 13:54:06 +00:00
adamdunkels 0b58ca3b22 Bugfix: split full size TCP segments if they match the MSS definition, not only the buffer size definition 2010-01-25 13:53:15 +00:00
adamdunkels 7615a6cf47 Bugfix by Henrik Mäkitaavola: check that ICMP6 process is defined before invoking it 2010-01-25 13:37:05 +00:00
adamdunkels 4f3e8d565c Added a simple CSMA (Carrier Sense Multiple Access) mechanism that 
works on top of an underlying duty cycling mechanism. The CSMA layer
retransmits packets that could not be sent because of a collision was
detected.
 2010-01-25 11:46:44 +00:00
adamdunkels 7ad93e5d18 Added a field to the struct mac interface: 
channel_check_interval(). This function returns the interval by which
the duty cycling mechanism checks the radio channel for activity. It
is used by higher layer mechanisms to determine suitable timeouts for
retransmissions.

nifi 7b2b93e6e6 clear transmission flag if send failed 2009-12-18 14:49:42 +00:00
zhitao 93c748cc74 Bug fix for mysterious packet loss : check FIFO pin instead of FIFOP pin for any unread RX FIFO data; 
Added protection of packet timestamp across interrupts. Note that race condition can still occur as interrupts and self-scheduled reads of the RX FIFO interleave in certain unusual patterns. More investigation is needed.
 2009-12-11 18:32:54 +00:00
adamdunkels f4e6758b22 Use RTIMER_NOW() instead of rtimer_arch_now() 2009-12-09 18:08:26 +00:00
adamdunkels eff2203310 There were many bugs in the rtimer code, particularly one that made only one rtimer at a time work. We have a new rtimer system that we're testing, but in the meantime, I rewrote the rtimer code to explicitly support only one rtimer. Makes the code significantly simpler (and fixes a bug that was very hard to track down). 2009-12-08 23:55:17 +00:00
adamdunkels 2f105e933a Variable xmac_is_on was used both in interrupt and non-interrupt contexts and needs to be volatile 2009-12-06 23:29:38 +00:00

adamdunkels 6897270289 Bugfix to the Contiki LPP encounter timing code: encounters are now 
properly timed.
 2009-12-06 13:18:32 +00:00
adamdunkels 822149f943 Significant improvements to the Contiki X-MAC: 
* the code is simplified, particularly the duty cycling logic
* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
  collisions
* broadcasts are sent directly, without strobes, reducing the power
  consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
  strobe ack
 2009-12-06 13:16:59 +00:00

fros4943 0034fd7bca generic return values for sent packet 2009-11-13 10:09:02 +00:00
fros4943 9cc57c4324 generic radio return values 
+ minor bug fix: SFD may go high without transmission starting (very seldom)
 2009-11-13 10:07:53 +00:00
fros4943 9b20f11cd8 chameleon returns 1 only on successful rime_output() 2009-11-13 09:14:52 +00:00
fros4943 583dd11c55 rime_output() now returns RIME_OK or RIME_ERR depending on the MAC return value. 
this patch may affect Rime sniffers running on top of MAC protocols that do not yet return generic MAC return values
 2009-11-13 09:10:24 +00:00

fros4943 5f71e9914e configurable line buffer size + simplified interrupt handler + overflow check on line buffer 2009-11-02 12:47:06 +00:00
adamdunkels 5aab2eb77d A simple addition with significant performance implications: 
sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM
flag, which makes the underlying power-saving MAC layer keep the radio
on for some time after transmitting the packet. This allows reply
packets to be processed directly, significantly increasing TCP latency
and throughput.

adamdunkels c7a91ad4a2 Bugfix: UIP_TCP_BUF -> BUF 2009-10-27 23:09:58 +00:00
adamdunkels 631af06c7c Bugfix: Active TCP connections in uIP are made by first setting up the 
TCP connection state, then poll uIP to send out the first SYN. Until
now, however, the SYN was not sent as part of the poll, but at the

adamdunkels 4de1816e36 Added a new module called "framer" that creates MAC level frames to

one that creates 802.15.4 frame headers, and one that creates a
minimal "nullmac"-style header that only contains the link-local

adamdunkels 9d26bd663e A new optimization to X-MAC: senders now keep track of when neighbors 
last were known to be awake. When sending a packet, a sender does not
start to send strobes until the neighbor is expected to be awake. This
reduces power consumption for senders and decreases the contention in
the network as there are less packets in the air. Additionally, the
ACK optimization was improved so that data/ack exchanges now are
more efficient.

cleaned up some code.
 2009-04-02 14:20:04 +00:00
nvt-se 1425537a13 Introduced two garbage collection mode: greedy and reluctant. 
The greedy GC mode attempts to erase as many sectors as possible, and
it is therefore a slow operation, since the flash driver must wait
for about a second after erasing one sector. The former behavior was
to always do a greedy GC if file reservations fails due to lack of space.

The new reluctant GC stops after erasing one sector, and therefore
we often do not have to wait if there is no file system operation
in the time while the sector is being erased. We call the garbage collector
using this mode when removing a file that is not a micro log file, since
the remove function is called recursively for micro log files that are
erased because the corresponding ordinary file is erased.

This change increases the coffee test (examples/sky/test-coffee.c) speed
from 9 to 5 seconds.

oliverschmidt bc3d9d2e3c Minor rearrangement. 2009-02-28 11:57:46 +00:00
oliverschmidt 938f151a66 Allow to override the whence macros individually - just like the open flags. 2009-02-28 11:39:02 +00:00
oliverschmidt a7cb609321 With dynamic loading enabled the function ctk_textentry_input_null() lives in the persistent core while the macro CTK_TEXTENTRY() is typically used in loadable modules. So ctk_textentry_input_null() needs to be dynamically resolved. 
On Win32 dynamic resolving isn't done by patching the dynamically loaded segments. Rather the code generated by the compiler for accessing symbols declared with __declspec(dllimport) is implicitly modified to actually go through pointer dereferenciations. The dynamic linker only initializes this pointers.

But with the symbol ctk_textentry_input_null becoming a pointer to a function it isn't a constant anymore and so it can't be used as initializer element - and thus breaking CTK_TEXTENTRY().

So the only viable solution seems to stick to the inversally available NULL pointer on Win32. But if there's an ugly #ifdef <platform> necessary anyway than it seems resonable to classify ctk_textentry_input_null as the special case and therefore use #ifdef SDCC:
- It saves some bytes on all non-SDCC platforms
- Is matches the exsisting inline documentation

adamdunkels 13a3029435 Rewrote the random_rand() pseudo random number generator to use the libc rand() function instead 2009-02-11 11:09:59 +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.

nvt-se d0a546b049 A long refactoring session yielded the following. 
Technical changes:

* Factored out file specific information from the file descriptor
  structure into a new file structure.

  - Useful file metadata can be stored after the file is closed.
  - File descriptors become much smaller.
  - Significantly reduces the need to scan for the file end.

* Use correct types in all function signatures.
* Removed the directory cache.

Results:

* Enormous speed increase when opening cached files (10x-20x.)
* Multiple fd:s pointing to the same file have the correct semantics.
* About 100 bytes smaller ROM size.
* Slightly smaller static RAM size.
