adamdunkels 148bd60fe1 Bugfix: the defensive retransmission timer setting must be made before the packet is transmitted, otherwise the retransmission timer will always be for the defensive retransmit 2011-01-09 23:49:27 +00:00
adamdunkels 50a3e6ea23 Increased the max ETX to allow for longer paths even with the initial conservative ETX estimate; made collect use announcements by default 2011-01-09 23:48:33 +00:00
adamdunkels acf45ec648 Bugfix: memory wasn't freed when a neighbor was dropped from the list. Also increase the max age to 180 minutes to allow for regular beacons to refresh the neighbor before it is dropped. 2011-01-09 21:20:05 +00:00
adamdunkels 90dc0ceebf Replaced default link estimator with an exponential weighted moving average, which reduces memory consumption per neighbor. 2011-01-09 21:14:22 +00:00
adamdunkels 4e91d9303e Added safeguard timer if the MAC layer would fail to call back after transmission. 2011-01-09 21:13:20 +00:00
adamdunkels cea299d79a Call upper layers even if packet reception failed - this allows the RDC layer to shut off the radio even if a malformed packet was received. 2011-01-09 21:09:28 +00:00

adamdunkels 4914739e5d Revived the timesynch module, which has been switched off since the introduction of the new radio API after Contiki 2.4. The new code uses explicit timestamp messages instead of piggybacking timestamps on every transmission. It is also significantly better in terms of exactness. 2010-12-16 22:47:38 +00:00
adamdunkels 10fb99a89d Reduced the value of the max depth, so that a count-to-infinity loop will not count too long before hitting the maximum value. This is important when a network loses its sink, so that packets are not forwarded around the network for ever. 2010-12-16 22:46:34 +00:00
adamdunkels 19e930e6f2 Changed the behaviour of retransmissions to work better with the in-order CSMA code. The retransmission timer is now set when the packet is known to be sent by the MAC layer. 2010-12-16 22:45:15 +00:00
adamdunkels 4a89cc9db3 Rework of the new CSMA in-order code that fixes a number of smalllish bugs in the in-order code. 2010-12-16 22:44:02 +00:00
adamdunkels 79f2c25dae Rework of the phase-lock optimization mechanism. There were several bugs in the existing code, such as the phase-lock would lose synchronization when a packet was lost. 2010-12-16 22:43:07 +00:00
adamdunkels 01c28ab502 Added explicit timestamp packet type, for the revived timesynch support 2010-12-16 22:41:43 +00:00

dak664 240d478c1f Allow platform to specify COLLECT_CONF_BROADCAST_ANNOUNCEMENT_MAX_TIME 2010-12-14 22:14:33 +00:00
adamdunkels 952dfc9384 Rework of the CSMA layer: instead of using one timer per packet, the module now uses one central timer and a queue of outgoing packets. This helps to keep packets in order, which is extremely useful for TCP transfers, and reduces the amount of congestion since consecutive packets now are spaced in time if there is a collision. Based on the observations and ideas of Simon Duquennoy. 2010-12-14 07:57:14 +00:00

nvt-se b2a28e6fc3 Fixed error reported by Pieter Agten. The reachable time is specified in milliseconds, and must thus be divided by 1000. 2010-12-06 09:48:48 +00:00
adamdunkels 4c9793f428 Let ContikiMAC remember the state that the radio should have when duty cycling is turned off. This fixes a bug in which the radio was turned on after sending, even when NETSTACK_RDC.off(0) was enabled. 2010-12-06 09:08:22 +00:00
adamdunkels 433d42e170 Bugfix: if the cc2420_cca() function wasn't able to turn on the radio properly, it should turn it off again if it was off before. 2010-12-05 00:14:24 +00:00
