Abstract: Apparatuses, methods, and systems for synchronizing nodes of a wireless network are disclosed. One method includes identifying synchronization paths between synchronization reference nodes of the wireless network and each non-reference node of the wireless network, wherein each synchronization path includes one or more wireless hops between the synchronization reference nodes and the non-reference node, determining a number of timing slots needed for supporting each of the identified synchronization paths, and selecting at least one of the synchronization paths between each non-reference node and at least one of the synchronization reference nodes based on a number of wireless hops of each of the identified synchronization paths and the determined number of timing slots needed to support each of the identified synchronization paths.
