adamdunkels 7165a3866f Significant rework of the Contiki data collection protocol: 
* the new version makes use of MAC-layer feedback so that bad paths
  can be identified quicker and then avoided.

* the new code uses transport layer ACKs that contain feedback from
  the collect protocol: when a packet cannot be forwarded due to lack
  of resources, the ACK contains a flag that indicates that the packet
  could not be forwarded. ACKs also contain the routing metric of the
  sender, which improves agility in face of rapid path changes.

* loop detection and management has been improved: with higher path
  metric agility, the system is more prone to short-lived routing
  loops. Instead of dropping looping packets, the new version adjusts
  the routing metric for the routes that exhibit loops so that the
  risk for future loops is reduced.

* make use of packet attributes to inform the MAC layer of how many
  times packets should be retransmitted.

adamdunkels b6b4941871 Made the number of MAC-layer retransmissions configurable on a per-packet basis, via a packet attribute 2010-02-28 08:35:16 +00:00
adamdunkels ed88f487c8 Improved detection of link-layer ACKs; increased the time ContikiMAC waits when it has detected a link-layer ACK; increased the number of silence periods required to detect a CCA false positive 2010-02-28 08:33:21 +00:00
adamdunkels fa1a96636e Bugfix: the compile-time check for UIP_LLADDR_LEN previously generated a run-time error, when it should have generated a compile-time error 2010-02-28 08:30:39 +00:00
adamdunkels ba0e50a7b7 Set the default number of MAC layer retransmissions for IPv6 packets to 2 2010-02-28 08:29:42 +00:00
adamdunkels 486f7f9728 Rewrite of the Sky shell collect test. The new test is better equipped 
to handle reordered packets - unlike the previous test, the new test
counts all incoming packets in the data stream, even those that are
significantly reordered. The new test also shows the received packets
and their hop counts in a much more readable fashion.

nifi c20047f657 Changed the network stack to use different structures for the different layers (network_driver, mac_driver, rdc_driver, radio_driver). This helps to avoid incorrect configuration. 2010-02-23 20:09:11 +00:00
adamdunkels bb62749de7 Made debug printfs optional 2010-02-23 18:49:58 +00:00
adamdunkels 0ab2ba433f Bugfix: the wrong callback pointer was passed to higher layers. 2010-02-23 18:49:45 +00:00
adamdunkels ed52586e18 Rework of parts of the ContikiMAC code based on input from experimental results. When channel check is triggered because of a false positive, the new version checks the radio several times to make sure that there really is an incoming packet. Otherwise, the radio is switched off. Cleaned up and removed old unused code. Added a few temporary debugging mechanisms and functions. 2010-02-23 18:49:05 +00:00
adamdunkels 14bc9aa98b New and improved shell collect test: the new test sends out 10 packets from each node and counts the received packets. If less than 10 packets from each node is received, the test fails 2010-02-23 18:46:20 +00:00

adamdunkels 465125c5e7 Added support for 32-bit clock ticks: when reading the 32-bit value, make sure that it does not change between readouts to avoid reading right in the middle of it being updated 2010-02-23 18:41:20 +00:00
adamdunkels 50e1452564 Ugly workaround for internal error in mspgcc when applying the >= operator to two 32-bit values 2010-02-23 18:40:08 +00:00
adamdunkels 0c4c88ae66 Improved per-packet power profiling: if a packet is retransmitted, the new energy is added to the old energy so that it is possible to measure the full energy for all transmissions of the packet 2010-02-23 18:39:00 +00:00
adamdunkels ca0417a923 Added the MAC layer callback functionality so that the Rime network layer gets information from the MAC about the status of sent packets: were they successfully transmitted, or was there a collisions? How many retries were there? 2010-02-23 18:38:05 +00:00
adamdunkels f10eedab3e Added debug printout 2010-02-23 18:37:15 +00:00
