706045120f Changed the variable name local_confidence to etx to better reflect what it was used for 2011-02-11 14:18:57 +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

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.
