摘要 在洪泛时间同步协议的基础上,提出一种层次时间同步协议。该协议采用层次结构机制收集统计网络中每个节点的子节点数,消除叶子节点广播信息数据包的环节。仿真实验结果表明,该协议可以取得与洪泛时间同步协议一样的精确度,且能量消耗仅为洪泛时间同步协议的74%。 This paper proposes and evaluates a new time synchronization protocol called Hierarchical Time Synchronization Protocol（HTSP） which is an advanced version of the Flooding Time Synchronization Protocol（FTSP）.The concept of hierarchy is adopted,and the hierarchy concept is used in collecting statistics for the number of child nodes of each node.With the collected number of child nodes,the HTSP can reduce the number of packet transmission.Simulation results show the energy consumption of the HTSP is only 74% of that of the FTSP.
