The Research on Time Synchronization Methods in Ad hoc Networks
Yijun Luo · 2007
A new method of time synchronization in Ad hoc networks is put forward.Time master-controlled node synchronization is combined with mutual synchronization.In this method time synchronization is linked with constituting network.Initial synchronization,when nodes constitute a network,realizes initial time synchronization by means of master-slave synchronization according to the entrance sequence.Nodes realize synchronization track by using mutual synchronization subsequently.Compared with conventional mutual synchronization,it makes initial synchronization faster and more accurate.Furthermore compared with usual time master-controlled node synchronization,it makes synchronization track more accurate and avoids bad effect caused by newly selected time master-controlled node.
