Neighbor ETX should accumulate over retransmission timeouts;
...
Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.

This is an initial commit of an implementation of the Chameleon
...
architecture for the Rime stack for Contiki. The Chameleon
architecture separates the header processing from the Rime protocol
logic. Instead of having each protocol create its own part of the
packet header, protocols use packet attributes. Before sending a
packet, a special Chameleon header processing module creates a packet
header from the packet attributes. The same Chameleon module parses
incoming packets and creates packet attributes from the header.
The details are in our SenSys 2007 paper:

Architecture for Wireless Sensor Networks. In Proceedings of the Fifth
