Abstract
Techniques configure a network to relay data from a node to a root device are described herein. In an example, one-hop neighbors of the node are determined and ranked according to link quality. The ranked neighbor nodes may be considered potential “parent nodes” of the node. The ranked nodes may be divided into a plurality of groups according to link quality. A parent node may be selected from among the “best” group of one-hop neighbor nodes and may be used to relay data for the node to and/or from the router or other device. The node continues to use the parent node at least until its ranking removes it from the best group or falls below a threshold value. After the ranking of the parent falls below such a prescribed threshold it may be replaced by selection of a replacement parent from the group of one-hop upstream neighbors having the best link quality.
