To achieve network-wide time synchronization in multi-hop Wireless Sensor Networks (WSNs), this paper proposes an accurate and energy-balanced time synchronization algorithm based on flooding. Flooding Time-Synchronization Protocol (FTSP) has advanced features, such as implicitly dynamic topology and high time accuracy, which can't be affected by some node's losing. FTSP propagates its time information of the reference node without concern about the network topology. However, in large-scale WSN applications, the efficiency of FTSP will be reduced drastically because of serious network storm.
