Claim Text:
1. A method of synchronizing a controller for an existing wireless mesh network, the method comprising: detecting, within the controller, that the controller is missing at least some sleep timing information previously distributed to wireless mesh network nodes in the existing wireless mesh network; sending a network synchronization signal from the controller to one or more wireless mesh network nodes in the existing wireless mesh network, wherein the network synchronization signal indicates that at least some sleep timing information previously distributed to the wireless mesh network nodes in the existing wireless mesh network is missing in the controller; receiving a reply from one or more wireless mesh network nodes within the wireless mesh network, wherein the reply includes at least some sleep timing information previously distributed to the wireless mesh network nodes in the existing wireless mesh network; and synchronizing the controller to the wireless mesh network nodes based on the sleep timing information received from the one or more wireless mesh network nodes.
