ace6567815 Added a timer that randomizes the retransmission of an incoming new trickle version to avoid broadcast collisions 2009-04-06 21:20:35 +00:00

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

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.

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

ba5c18a468 Rewrote the trickle code to run directly over the broadcast primitive: the previous implementation did not work as expected, because packets were not supressed correctly by the previous underlying netflood primitive 2008-07-07 23:29:30 +00:00

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.

d2be099c0e Bugfix: queue buffers were not freed when a new packet was sent, leading to memory leakage. Added debug output. 2008-01-08 07:59:51 +00:00
