The tag node demand small volume and low consumption in wireless sensor network.Synchronal information which is used for the tag node receiving signals is extracted by the synchronizer in the tag node.The precise synchronization scheme will increase the complexity of the tag node,so a scheme that the anchor node synchronizing the tag node actively is introduced.This scheme can reduce the complexity of tag node and strive to reduce energy consumption under taking the complexity of anchor node no account.Acquisition conditions and an algorithm are analyzed about this scheme.The performance of the proposed scheme is evaluated in terms of mean acquisition time and mean times which are required by the tag node confirming feedback.Finally,the simulation results verify the accuracy of theoretical analysis,and show that the scheme is feasible.
