Researching the long-term effective energy time synchronization protocol is a key strategy for successful deployment of the vitality of wireless sensor networks. This proposes a low-power multi-hop adaptive time synchronization algorithm( the MATS: Multi-hop adaptive time synchronization). The algorithm designs a flexible mechanism to adjust the synchronization mode,re-synchronization cycle,and each pair of node synchronization beacon number,and using the maximum likelihood estimation principle at the same time on the node clock offset and frequency offset estimate achieved with minimum energy loss to the completion of a long-term,network-wide time synchronization purposes. At last,the improved algorithm is verified through mathematical analysis and simulation methods.
