Research on the Algorithm of On-Demand Time Synchronization for Wireless Sensor Networks

Time synchronization is a supporting technology in wireless sensor networks.But now there is relatively less research on lowering energy consumption in multi-hop time synchronization.As above reasons,on the groundwork of TPSN,this paper presents a low energy-consumed time synchronization algorithm which fits the multi-hop wireless sensor networks.In this algorithm,we expatiate single-node and multi-nodes synchronization algorithm,and analyze their precision and complexity.Emulational experiments prove that,comparing with TPSN,our algorithms have the same precision,lower complexity and lower energy consumption.
