a093c262ee Improved objective function API so DAG metric containers can be generated cleanly. The packet generation now asks the OF to provide a fresh logical presentation of the metric container, which is then translated to raw packet format. 2011-02-15 01:13:30 +01:00

2a96835c05 Don't remove all parents that have a worse rank than an incoming DIO: we may inadvertently remove our preferred parent. Instead, remove parents with a rank that is worse than our preferred parent. If we are lucky, this will give us enough space for the new parent. 2011-02-13 14:16:15 +01:00

ba6bf7dd6b Rewrote the parent selection to favour parents with a low ETX and a good rank. The old parent selection would always favour parents with a lower rank, regardless of their ETX, which in some cases lead to suboptimal parent selections. Also, the old code was buggy in that it would always pick the worst parent (the one with the highest ETX). 2011-02-11 14:17:26 +01:00

09c223f549 Updated Contiki X-MAC to use hardware acks, which allows for tighter timing and results in a lower duty cycle. Hardware acks also make X-MAC more robust against packet losses, as there is a direct way for the CSMA layer to detect loss of data packets. Before, Contiki X-MAC only detected loss of strobes. 2011-01-25 14:31:09 +00:00

81d23a3a36 Minor bugfixes pertaining to queue handling: if a packet was explicitly dropped, the packet would later be acknowledged despite it never being received; added a limit on how many queue entries that can be used for packets that are being forwarded, to allow for originated packets even if the forwarding queue is filled. 2011-01-10 15:10:43 +00:00

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

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

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
