f701615afa bugfix: remember active transmissions (sender side) instead of last received packets (receiving side). allows several nodes sending to a single receiver.
+ added function for checking if runicast is currently transmitting (non-acked) data

9816f49fe6 Changed listen and transmit energy attributes so that they are named _TIME rather than _ENERGY, to indicate that they contain the time during which the radio was switched on and not the energy 2009-03-02 22:00:41 +00:00

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

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.

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

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

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

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

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

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.

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

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.

31509ad726 Fixed a bunch of bugs in the collection neighbor announcement/discovery code: neighbor announcments were not repeated unless there was a change in the ETX val. Neighbor announcements happened to often when there were changes in the ETX. 2008-08-15 19:00:38 +00:00
