摘要
传统的无线传感器网络时间同步机制属于前摄时间同步,耗能较高。为了对无线传感器网络的时间同步机制进行改进,本文分析了无线传感器网络中基于“后同步”思想的时间同步机制,对其中的路由结合的时间同步协议进行了详细的阐述,并在此基础上通过对各节点进行时钟偏差补偿,以尽量减小该协议产生的时间误差。
The traditional wireless sensor network belongs to proactive time synchronization,consuming too much energy.In order to improve the time synchronization mechanism of wireless sensor network,this article analyses the time synchronization mechanism based on post-facto in wireless sensor network, expatiates on routing integrated time synchronization protocol,and carrys on clock skew compensation on nodes to reduce the time error caused by the protocol.
