adamdunkels f50b8db53b Implement repeats with a periodic second timer to allow for greater range than what is possible with Contiki ctimers. Use RTIMER_NOW() instead of rtimer_arch_now(). 2009-12-09 18:12:23 +00:00
adamdunkels f4e6758b22 Use RTIMER_NOW() instead of rtimer_arch_now() 2009-12-09 18:08:26 +00:00
adamdunkels 9ac4109bad Increased the clock speed to 32768/4 from 32768/8 to provide better accuracy for power profiling of radio CCA checks 2009-12-09 12:55:35 +00:00
adamdunkels eff2203310 There were many bugs in the rtimer code, particularly one that made only one rtimer at a time work. We have a new rtimer system that we're testing, but in the meantime, I rewrote the rtimer code to explicitly support only one rtimer. Makes the code significantly simpler (and fixes a bug that was very hard to track down). 2009-12-08 23:55:17 +00:00
adamdunkels f9260c4fae Enable interrupts during the periodic clock processing to allow rtimers to execute on top of the clock 2009-12-08 23:40:14 +00:00
adamdunkels a4df6e0fbf Remove the read from TAIV - this should not be done for TIMERA0 interrupts (in fact, doing so messes up the other timer a interrupts, like the clock tick...) 2009-12-08 23:39:45 +00:00

adamdunkels 6897270289 Bugfix to the Contiki LPP encounter timing code: encounters are now
properly timed.

adamdunkels 822149f943 Significant improvements to the Contiki X-MAC:
* the code is simplified, particularly the duty cycling logic
* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
  collisions
* broadcasts are sent directly, without strobes, reducing the power
  consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
  strobe ack
2009-12-06 13:16:59 +00:00

fros4943 2f9ccfa26d merged mspsim's compile dialogs 2009-12-02 16:27:32 +00:00
fros4943 8bd7187491 the simulation object now handles the motetype configuration for motes; common functionality that was earlier implemented in each mote.
this patch allows the simulator more freedom for hand-picking mote class loaders

+ some debug output in experimental ImportAppMoteType
2009-11-27 15:53:10 +00:00
fros4943 a1b4597b95 fixed announcement compilation error 2009-11-27 14:27:50 +00:00

fros4943 236a6eee15 added new application mote type that loads a configurable application mote java class.
the new mote type makes it easier to create and load new application-level motes
2009-11-25 20:52:33 +00:00
fros4943 fa26d2f213 configure and load methods may throw a MoteTypeCreationException 2009-11-25 20:48:22 +00:00

fros4943 ac424ca88a bugfix: interfered nondestination radio 2009-11-25 18:13:05 +00:00
fros4943 7d6ee814da added documentation 2009-11-25 16:05:47 +00:00
fros4943 ff93ba8e0f decreased transmission interval and increased transmission duration of disturber mote, since short packets could still get through with the current settings 2009-11-25 16:03:00 +00:00
fros4943 d77d7ab667 updated mspsim.jar: implements cc2420's crc footer 2009-11-25 15:51:15 +00:00
fros4943 451be82efd radio connection update: radio should not be removed from destinations, but instead flagged as interfered.
(and the radio medium will keep delivering data also to interfered destinations to avoid the half-filled RXFIFO problem)

+ minor fix: the received signal strength is the maximum of all sending radio
2009-11-25 15:49:58 +00:00
fros4943 5c67d113c8 minor bug fix: arraydequeue may return null entries 2009-11-25 15:44:51 +00:00

fros4943 24d0330d2d radio connection update: radio should not be removed from destinations, but instead flagged as interfered 2009-11-25 15:43:03 +00:00
fros4943 45d23c026e new radio medium method signature + increased history size 2009-11-25 15:40:46 +00:00
fros4943 0a9e9dea59 * observing motes' radio states ("is transmitting") instead of radio events ("started transmitting").
previously the last radio event was logged in the Timeline, which could be very confusing when a radio was interfered while transmitting a packet: it looked like the radio stopped transmitting. (this behavior did not, however, affect the simulation output but only the timeline)

* added Radio Logger menu option shortcut, for quickly moving from the Timeline to the Radio Logger plugin
* minor ui fixes regarding event tooltips: tooltip info appear at mouse clicks
2009-11-25 15:39:57 +00:00
fros4943 d27a2dfb5b added Payload Alias for easier overview of several packets with identical payloads.
added Timeline menu option for quickly viewing the selected radio packet in the Timeline plugin.
2009-11-25 15:32:34 +00:00
fros4943 d4f674c053 updated obsolete method signature:
when the radio medium was still tick-based, several radio connection could finish "simultaneously" (during the same tick), which is no longer possible
2009-11-25 15:26:35 +00:00
fros4943 2955eb9798 distinct between a radio connection's interfered radios, and interfered destination radios: interfered destinations still receive connection data
+ faster code and updated documentation
2009-11-25 15:21:15 +00:00
fros4943 7e6fbd9f7b output warning if radio shuts down during transmission 2009-11-25 15:18:11 +00:00
fros4943 01e9498dd9 radio medium update: receiving nodes that become interfered still receive connection data, but may (should) choose to ignore or corrupt it.
this solves a problem with half-filled FIFO buffers on CC2420 radio platforms

+ minor fixes: the received signal strength is the maximum of all active connection, and a transmitting radio may still be interfered
2009-11-25 10:36:08 +00:00
fros4943 5ed294f001 minor patch: remember last exported jar filename 2009-11-25 10:29:21 +00:00
fros4943 c0e115895d when a receiving radio is interfered by another transmission, the actual data received is corrupted. 2009-11-25 10:01:55 +00:00
