| 摘 要： | 针对无线传感器网络中时间同步技术应具有高效率且节省资源的要求,给出了一种改进算法：使用时间同步有效性检查阶段的时间戳,在只发送一个小数据包的基础上实现同步功能,使所需消息传输量较传统算法少得多,既提高了同步效率,又降低了能源消耗,并兼顾了应用场合的精度要求,仿真结果验证了该方法的有效性。

| Abstract: | In view of the requirement that time Synchronization technology of WSNs should be highly efficient and resource-saving,an improved algorithm is provided as follows： using time stamp of the validation stage in synchronization,sending a small data packet that is able to achieve the synchronization function which requires less message transmission.In this way,not only the synchronization efficiency is improved,but also energy consumption is lowered and accuracy requirement is met in real situations.Simulation results have proved the validity of the algorithm. |
