fros4943 97f76126e6 remembering last received packet id to avoid multiple recv callbacks for the same retransmitted packet (but still sending back acks of course) 2009-02-17 12:40:18 +00:00
c_oflynn 8516626703 Fixed documentation error (thanks to David Kopf) 2009-02-17 01:28:28 +00:00
adamdunkels 36bb3ece64 If no neighbor is found, we listen for announcements. Cleaned up debug output. 2009-02-16 01:18:53 +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
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 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
nvt-se 98f7f9a06a sizeof on coffee_fd_set is no longer suitable since it has become a
pointer.
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
cache much smaller on most platforms.
2009-02-03 16:21:53 +00:00
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.
2008-11-12 10:47:17 +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 312afede00 Bumber version number to 2.2.2 2008-11-09 12:28:28 +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 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
