  • Systems and methods for synchronization target selection in wireless networks
    Patent number: 10212677
    Abstract: The present disclosure relates to methods and systems for selection of synchronization targets. Embodiments of the present disclosure provide for selecting a synchronization target for a network device, within operational network constraints, when the network device loses its current synchronization target. When a network device loses its current synchronization target, the stratum index of the network device is downgraded to an artificial stratum index before a selection of a new synchronization target is made. The artificial stratum index is broadcast to children network devices. Downgrading the stratum index to an artificial stratum index allows for selection of available synchronization target network devices with stratum indices higher than or equal to the network device's stratum index. After selection of a new synchronization target, the network device's stratum index is updated, and the new updated stratum index of the network device is broadcast to the children network devices of the network device.
