摘要:
A device and method for of synchronizing a MAC superframe of a wireless device is disclosed. The wireless device can be located within a chain of a plurality of other wireless devices. The method includes receiving beacons from at least one other device during a superframe of the wireless device, determining a superframe offset for each of the other wireless devices based on timing of the received beacons, determining a corrective delay based on the superframe offsets, inserting the corrective delay within a current superframe of the wireless device, and inserting a predictive delay within the current superframe, the predictive delay being determined by an estimate of a difference between a frequency a clock of the wireless device and a frequency of a slowest clock of the other wireless devices within the chain.
