| Abstract: | Time synchronization is one of the important support technologies for wireless body sensor networks(WBSN).Aiming at the limited energy in WBSN,an improved time synchronization algorithm is proposed.The algorithm combines unidirectional reference broadcast mechanism with pair-wise message transfer mechanism,and can reduce the number of message transfer,reduce communications overhead while guaranteeing the synchronization precision,so as to save the energy consumption.Finally,the performance of this algorithm... |
