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.

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 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.

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

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

adamdunkels 6951d9d582 Removed the unused ->u16 field (it was there only as a convenience/laziness access method during the initial development of the Rime stack, but has caused problems when being there) 2008-11-30 18:26:06 +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 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 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
