adamdunkels 4e0744954a Rewrite of important parts of the Collect logic: link estimation
calculation and parent selection.  This fixes a severe bug that caused
loops when packets were erroneously retransmitted due to ACK loss.
2010-09-08 19:21:45 +00:00
adamdunkels 3fa8ffda1a Moved the modules packetbuf, queuebuf, and packetqueue from net/rime to net/, since they are not Rime-specific 2010-06-14 19:19:16 +00:00
adamdunkels 8f8393aadc Moved ctimer.[ch] from their old and illogical location in core/net/rime to a more appropriate place in core/sys 2010-06-14 07:34:36 +00:00
adamdunkels 2e8bfa5d9a Include new broadcast-announcement and renamed collect-neighbor in compilation 2010-03-19 13:21:24 +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 c489b1118d New module: packetqueue. The packetqueue module maintains packet queues for other modules. 2009-04-29 20:47:30 +00:00
nifi eab96e9b53 added rime-udp.c 2009-04-06 14:10:57 +00:00
nvt-se c531f25c94 A module that enables Rime to run over UDP. 2009-04-06 13:13:26 +00:00
adamdunkels 65eb5fd4e8 Renamed the rimebuf module to packetbuf to signal that the module is used outside of a pure Rime context (e.g., the sicslowpan code uses it). 2009-03-12 21:58:20 +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.

adamdunkels a0c833da11 Mistakenly included development code in the Makefile target 2008-02-25 13:22:34 +00:00
adamdunkels 412facb831 This is an initial commit of an implementation of the Chameleon
architecture for the Rime stack for Contiki. The Chameleon
architecture separates the header processing from the Rime protocol
logic. Instead of having each protocol create its own part of the
packet header, protocols use packet attributes. Before sending a
packet, a special Chameleon header processing module creates a packet
header from the packet attributes. The same Chameleon module parses
incoming packets and creates packet attributes from the header.

The details are in our SenSys 2007 paper:

Architecture for Wireless Sensor Networks. In Proceedings of the Fifth
ACM Conference on Networked Embedded Sensor Systems (SenSys 2007),
Sydney, Australia, November 2007.

This is a rewrite of the code that was developed for the paper.

adamdunkels 02ee418313 Moving timesynch.[ch] from sys/ to core/net/rime as they have more to do with Rime than with the kernel 2008-01-14 14:22:16 +00:00
