任务型水资源监测传感器网络移动节点时间同步与定位研究
Research on time synchronization and localization of mobile nodes in task-based water resource monitoring sensor network
摘要
Abstract
In order to ensure the accuracy and reliability of water resources monitoring data,a method of mobile node time synchronization and localization in task-based water resource monitoring sensor network is proposed.The MU Sync protocol is used as the time synchronization protocol for the network to synchronize the time of nodes within the cluster.Linear regression is used to estimate the clock drift rate of the network,and RSSI ranging is combined with DV Hop algorithm to roughly locate mobile beacon nodes.The improved whale algorithm is used to solve the optimal position of mobile beacon nodes,thereby improving the positioning accuracy of mobile nodes in the water resource monitoring sensor network.The testing results show that the time synchronization error is less than 10 μm with the increase of hops under different node numbers.The positioning error values in both shallow and deep waters are less than 50 cm,ensuring that the positioning coverage of all nodes meets the application standards.关键词
