Abstract
Systems and methods are disclosed for prioritized associations between parent nodes operating on a time-slotted channel hopping (TSCH) network and child nodes installed in one or more home area networks. Upon initialization and bootup, a child node scans for one or more available parent nodes on the TSCH network. If there are less than a threshold number of available parent nodes within communication range of the child node, the child node transmits a prioritized association request to the parent node. The parent node supports prioritized association requests by reserving at least one connection slot for child nodes requesting prioritized association.
