摘要
介绍了时钟同步算法在无线传感器网络中的应用及需求,并分析了性能参数和时间同步的误差。介绍了基于层次的传感器网络时间同步算法,进而提出了比较有价值的节省能量消耗自适应的同步算法。
The application and requirements of time synchronization algorithm in wireless sensor network were introduced firstly,and the certain metrics and time synchronization error were analysed.Base on administrative levels' time synchronization algorithms in wireless sensor network were introduced,then a valuable,energy-saving self-adaptive time synchronization algorithms was put forward.
