Time synchronization is an important support technology of wireless sensor networks(WSNs).About the existing protocols such as RBS
TPSN and CHTS
more consideration are taken to the time accuracy and planar network
which bring larger energy consumption.An low-overhead time synchronization protocol of WSNs based on dynamic clustering is implemented
fully taking characteristics of WSNs
such as network topology and limited power into account.The algorithm uses LEACH protocol to select the first node
topology of breadth-first spanning tree is implemented to choose the members of cluster.Time synchronization is divided into two parts
and colligates one-way broadcasting and two-way paired technology.The performance analysis and experimental results both show that this time synchronization algorithm can reduce synchronization consumption and improve the precision
