    Doppler auxiliary time synchronization algorithm for underwater acoustic sensor network by Xiao-ning FENG, Zhuo WANG, Xiao-long ZHU, Wen ZHANG

    Published 2017-01-01
    “…Time synchronization problem in underwater acoustic sensor networks (UWSN) was studied.Due to the propagation of acoustic signals in underwater environment and nodes movement bring some problems to time synchronization.A distributed time synchronization algorithm was proposed based on Doppler method,called NU-Sync.NU-Sync solved the problem of uncertainty propagation delay caused by nodes movement through calculating relative velocity.And autonomous underwater vehicle (AUV) was used as beacon node which can save energy consumption in the process of calculation clock skew.Simulation resulted show NU-Sync achieves high level time synchronization precision.…”

    Multi-level feedback based time synchronization algorithm for wireless sensor networks by HUANGFU Wei1, ZHOU Xin-yun1, CHEN Can-feng3

    Published 2009-01-01
    “…Aiming at the fast and efficient time synchronization protocol for the wireless sensor networks under resource constraints, a novel feedback-based full-scale time synchronization(FTS) algorithm was proposed.The basic idea of FTS is to execute iteratively time synchronization downlink operations on all the nodes of the wireless sensor network and collect the two-way path delay information from only a part of nodes to calculate the average delay adjustment per hop.The stochastically feedback scheme is adopted to reduce the uplink packets.The FTS algorithm also consists of the mechanisms of synchronization error monitoring and clock skew correction.The FTS was implemented on the popular TelosB sensor nodes from UC Berkeley.The experiments show that FTS is a fast, resource-efficient algorithm with ra-tional synchronization precision.…”
