adamdunkels cc3f609eaa Bugfix for alignment issue. Added mechanism that allows five duplicate announcements before suppressing one's own. 2010-01-25 13:55:17 +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

 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.

adamdunkels 70fc23ac7e Enable stream mode by default, remove LED debug mode 2009-11-04 16:02:45 +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.
 2009-11-02 11:58:56 +00:00
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
first retransmission. This is now fixed.
 2009-10-27 22:34:08 +00:00

adamdunkels 7cdfbca973 Alignment problems with announcements fixed 2009-10-19 21:27:02 +00:00
adamdunkels 9ec57d61ad Added MAC layer framing support to X-MAC so that packets now are standard 802.15.4 frames 2009-10-19 20:53:56 +00:00
adamdunkels 4de1816e36 Added a new module called "framer" that creates MAC level frames to 
the packetbuf from packet attributes. Two framer modules are included,
one that creates 802.15.4 frame headers, and one that creates a
minimal "nullmac"-style header that only contains the link-local
addresses.

adamdunkels f25856a387 Hack to be able to receive UDPv4 multicast packets 2009-10-18 22:03:44 +00:00
adamdunkels fb037e0afb Added function for sending an UDP packet to a specified IP address and port number over an existing UDP connection 2009-10-18 22:02:01 +00:00
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.
 2009-10-18 13:19:25 +00:00
nvt-se 31f41d842e * decline route discovery requests if we have one in the air

adamdunkels 02734c9806 Bugfix: must copy the sender and receiver addresses from the packetbuf buffer, otherwise an application program may overwrite them 2009-05-10 21:10:02 +00:00
adamdunkels fe5a1f1068 Added an optimization option that avoids multiple simultaneous broadcasts from neighbors: when a broadcast is to be sent, a sender does not send until it knows that no other nodes are broadcasting. 2009-05-10 21:09:05 +00:00
adamdunkels fe30886b37 Added functionality for decaying routes: when a packet is sent over a route, it is decayed. If the route is not refreshed within four packets (with the route_refresh() function, which is called when a new packet arrives), the route is dropped. A route can be decayed at most once per second 2009-05-10 21:08:01 +00:00
adamdunkels 6bf8e0b478 Bugfix by Takahide Matsutsuka: too few items in array, which caused problems with sdcc 2009-05-08 08:52:55 +00:00
zhitao 48d4800f08 removed reference to undefined function in mspgcc 2009-05-06 15:34:28 +00:00

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.

 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 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 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
nvt-se 883d10e136 GC fix: isolated pages must always be allocated. 
page allocation: increased utilization because the algorithm failed to
count all space before.

style: renamed and simplified some code and names.
 2009-02-14 19:09:17 +00:00
nvt-se b8f3dca765 fixed merge_log bug and space allocation error with isolated pages. 2009-02-12 11:24:22 +00:00
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.
 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 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
nvt-se 98f7f9a06a sizeof on coffee_fd_set is no longer suitable since it has become a

 2009-02-09 12:02:10 +00:00
fros4943 4f7f3c97b5 * added coffee_files to the protected memory needed during cfs-based checkpointing operations 
* renamed cfs_coffee_get_fd_set() to cfs_coffee_get_protected_memory() to highlight that not only fd_set is protected
 2009-02-09 10:08:26 +00:00
adamdunkels dd9ffd87c4 Added missing #include announcement.h 2009-02-08 20:14:18 +00:00
adamdunkels 085df6b630 Improved version of LPP with support for broadcasts as well as announcement data in the probes 2009-02-08 19:30:18 +00:00
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.
 2009-02-08 17:08:13 +00:00
adamdunkels 91d280c4c9 Reverted to the old behaviour on broadcasts: send strobes for both unicast and broadcast packets. 2009-02-07 18:45:50 +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 bf39076206 added experimental checkpointing functionality: 
currently only implemented on the sky platform
 2009-02-04 17:49:15 +00:00
nvt-se fda75c4c08 Use the right type for pages in the directory cache. This makes the

nvt-se 4b56200586 documented the new function that helps sensornet checkpointing to protect 
file descriptors while rolling back state.
 2009-01-29 18:24:58 +00:00
adamdunkels e346d8cf95 Reverted the timer_expired() back to the previous version (which should be correct). Removed the definition of CLOCK_LT() because it seems to only cause problems. 2009-01-24 15:20:11 +00:00
adamdunkels 3a4a961ff5 Fixed the CLOCK_LT again. The previous revert was incorrect: the conditional was missing due to a bad copy-and-paste on my part :( 2009-01-24 10:54:44 +00:00
fros4943 8f462b9a52 zeroed debug flag 2009-01-23 17:28:09 +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.

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 6a460fecdd There is problem with the CC2420 driver: under high traffic load the packets often get mangled in the receive FIFO. Not sure why this happens or how to best prevent it. As a temporary workaround, I've added an additional CRC16 check to the incoming packets. This eats two bytes from each packet, but at least protects against the erroneous packets we've seen quite a few of lately. The reception code was also cleaned up, which resulted in a smaller code size. 2008-08-26 21:44:03 +00:00
