| 摘 要： | 为提高无线传感器网络中节点间时间同步的精度并且降低节点能量消耗,提出了一种基于移动节点与静态节点混合网络的时间同步方法.先建立一个带移动的节点的分簇网络结构,再结合发送者一接受者与改进的发送者一发送者两种同步模型从多个移动节点同时发起同步.通过数学分析和仿真得出该同步方法在同步时间精度和节点节能方面具有良好的性能.

| Abstract: | To improve the time precise between the nodes in WSN(wireless sensor network) and reduce the energy consumption of the nodes,a time synchronization approach which introduces the mobile nodes is proposed.Firstly,the network with some mobile nodes is clustered and then the sender-receiver and advanced receiver-receiver models is utilized to synchronize the new network archi-tecture from different mobile nodes simultaneously.The mathematical analysis and simulation results show that it performances well in syn... |
