ABSTRACT:
A method and apparatus for adjusting an oscillator in a network for correcting frequency drift is disclosed. Nodes in the network exchange time stamp messages with each other. The time stamp messages contain the time the stamp message is transmitted, node measurement value 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.
