nvt 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

Adam Dunkels 15bf73ba08 Use DAG_RANK() macro to compute rank 2011-02-13 19:01:15 +01:00
Adam Dunkels e980072817 Don't add neighbor as a potential parent if its rank is too high. 2011-02-13 18:05:28 +01:00
Adam Dunkels 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

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.

  the maximum stack depth.

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