Abstract: Examples include a coordinator device broadcasting a route request identifying a destination device, to neighbor routers over reception paths. The neighbor routers then store a respective route record, indicating each as an end node in an in-progress path from the coordinator device to the destination device, and rebroadcast the route request for reception by next increment router neighbors. The next increment router neighbors, responsive to receiving the rebroadcasts, estimate a quality between good hop and bad hop of their reception paths, and determine, as an evaluation total path quality, a quality of a candidate hop path from the coordinator device to the next increment router neighbor. The next increment router neighbors determine if they have extant hop connection to the coordinator device with path quality at least as good as the evaluation total path quality. If “no,”, the next increment router neighbor increments the hop sequence by one hop.
