nvt-se adf6961a85 Various bug fixes and adjustments for rpl-11 2010-09-15 13:22:22 +00:00
nvt-se e000b1abf3 A major update to ContikiRPL resulting in a reduced code footprint by 
300 bytes, as well as cleaner protocol logic.

* Made parent management uniform.

* Simplified the DIO processing.

* Improved the Objective Function API and its documentation.

* Removed redundant code at various places.

* Improved identifier naming.

* Switched visualization from candidate parents to preferred parents only.

* Made DAO ACK transmissions configurable.

* Improved initial ETX guess by using a cached local confidence value.

* Added a periodical rank recalculation function to reduce
  the maximum stack depth.

* Increased the Trickle redundancy constant to ensure faster
  topological updates.

Control that dst_adv_supported is set before sending DAOs.
