SYNCHRONIZATION OF NODES |
摘要 |
A method and apparatus for adjusting an oscillator in a network for frequency drift. Nodes in the network exchange time stamp messages. The time stamp messages contain the time the time stamp message is transmitted, the nodes measurement of an interval and an uncertainty value for the nodes estimation of the interval. By exchanging measurements of common intervals, nodes can determine how far their oscillators have drifted from the correct oscillating frequency.
