摘要 时间同步技术是无线传感器网络中非常重要的协议之一,也是其他协议可靠运行的前提条件,近年来也有相当多的同步机制被提出来,在大规模的无线传感器网络中,单跳同步误差的累加,时钟偏移与漂移同时补偿,同步机制的拓扑性能,同步收敛速度等是目前同步机制研究过程中的主要挑战,传统的集中式同步机制无法满足大规模无线传感器网络的性能要求,研究者们也提出了梯度同步机制,协作同步机制,以及分步式同步机制等来应对这些挑战。本文详细的分析了这些同步机制,并探讨了未来可能的发展方向。 Time Synchronization is one of important protocol for Wireless sensor network,it is the prerequisite for other protocol reliable operation.There have a lot of Time Synchronization algorithms been proposed,in the large-scale wireless sensor network,research a new time synchronization mechanism has a lot of challenge,such as,the accumulation of single-hop error,the compensation of time offset and time drift,topological properties of Synchronization mechanism,and Synchronization convergence.Traditional centralized synchronization mechanism can not meet the performance requirements for large-scale wireless sensor network.Distributed Consensus Time Synchronization,cooperative synchronization,and Gradient Clock Synchronization present some new solution to time synchronization for wireless sensor network.We detailed analysis these time synchronization mechanism,We also proposed the future research directions.
