Nicolas Tsiftes	93a7280a1a	Replaced old description	2011-02-15 18:10:15 +01:00
nvt	99d0387a8e	Merge branch 'master' of github.com:adamdunkels/contiki-2.x	2011-02-15 01:13:41 +01:00
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	db37e38156	Make sure we don't remove the preferred parent	2011-02-14 23:01:11 +01:00
nvt	cbe4513bf4	basic support for parsing metric containers in DIOs	2011-02-13 23:17:56 +01:00
nvt	539ff33104	Turn off debugging	2011-02-13 21:36:07 +01:00

Adam Dunkels	432928d000	Changed the name of macros defined in neighbor-info.h to have the NEIGHBOR_INFO prefix.	2011-02-13 21:29:59 +01:00
Adam Dunkels	acb5480aa9	Changed the name of macros defined in neighbor-info.h to have the NEIGHBOR_INFO prefix.	2011-02-13 21:21:14 +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
Adam Dunkels	f1ac94e415	Slight code complexity reduction	2011-02-13 14:14:49 +01:00
Adam Dunkels	3a824d0ed6	Added a hysteresis when choosing a new parent: don't switch parent unless the ETX is significantly better (1.5 ETX better).	2011-02-13 14:14:16 +01:00
Joakim Eriksson	48fb9dda9e	fixed of0 to respect min hop rank increase	2011-02-13 11:25:53 +01:00
nvt	20171985c6	Split the RPL header into a private and a public header.	2011-02-11 16:21:17 +01:00
Adam Dunkels	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
Adam Dunkels	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
Joakim Eriksson	d24c63c0f1	fixed so that minhoprankinc is configurable	2011-02-10 19:44:12 +01:00
