| 摘 要： | 针对水下动态传感器网络定位的特点及问题,提出了一种基于到达时间差(TDoA)的多频率主动定位方法MFALM(multi-frequency active localization method base on TDoA)。该方法将网络节点分为3组:信标节点、中继节点和普通节点。节点之间通过高、低两种频率分别进行近、远距离通信。为减少通信开销,定义了精简的报文格式和有效的通信方式。分析表明,该定位方法由于采用事件驱动、多频通信、精简报文,因此在定位过程中不但能够减少节点的定位开销,延长网络生存时间,而且还有定位精度高、节点密度可调等优点。

| Abstract: | We studied several fundamental key issues of localization in underwater sensor networks(UWSNs),then proposed an multi-frequency active localization method(MFALM) based on the time difference on arrival(TDOA) for UWSNs.The method,which is event-driven,divides all the nodes into three groups:buoy nodes,relay nodes,and ordinary nodes.To guarantee the low-power and effectiveness of communication,the nodes communicate with each other by two types of frequencies:low frequency and high frequency,the former is used... |
