Adam Dunkels 2a2175a214 Make RPL DIS transmission interval random in the interval [0, INTERVAL/2]. This is needed to avoid synchronization in large RPL networks. 2012-11-27 23:04:31 +01:00
Adam Dunkels 2396f9b8ea Made DIO interval processing a little easier to follow. Explicitly state that the delay is handled as clock timer ticks. 2012-11-27 23:04:31 +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 2a96835c05 Don't remove all parents that have a worse rank than an incoming DIO: we may inadvertently remove our preferred parent.

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
