Abstract
Systems and methods are disclosed for reconstructing a personal area network (“PAN”) after a failure in a system or network. A method can include detecting, by a node, a power failure in a system. The method can further include storing, by the node, data about a parent node in the system at a time of the power failure. The method can further include detecting, by the node, power restoration in the system and entering a restoration state in response to detecting the power restoration. The method can further include transmitting, by the node and to the parent node, an enhanced beacon request via a particular frequency channel associated with the parent node. The method can also include receiving, by the node, an acknowledgment response from the parent node via the frequency channel and receiving, by the node, an enhanced beacon request from the parent node via the frequency channel.
