Abstract
A method of selecting a parent node for routing from among a plurality of nodes in a 6TiSCH network. The method comprises; each of a two or more nodes of the plurality of nodes transmitting a routing message at each power level of a plurality of power levels, wherein the routing message comprises an indication of the reliability for a transmission path to a root node. The method further comprises, at a deciding node, receiving said routing messages from said two or more nodes, determining respective likelihoods of reliability of transmission to a root node via each of said two or more nodes based on the received messages and the indications, and selecting, as the parent node from the two or more nodes the node which has the greatest likelihood of reliability of transmission.
