| 摘 要： | 声源定位是无线传感器网络重要的应用领域之一.由于实际环境中的声源大部分是运动的,因此设计一种快速准确的声源定位协议是关键.文章研究了一种多传感器节点协同的声源定位协议,完整考虑了节点处理声音和射频信号的响应时间,分析了它们对该声源定位协议定位精度的影响,推导出声源定位边界性条件.实验结果表明该协议相对于现有的精确声源定...

| Abstract: | Acoustic source localization is an important application in wireless sensor networks(WSNs).Because most of sound sources are moving in surveillance field,it is a key problem to design a fast and accurate acoustic source localization protocol.This paper presents an acoustic source localization protocol based on the multi-sensor collaboration.The responding time of processing sound and RF signals for sensors is taken into account,the influence of them on the localization accuracy of the protocol is analyzed,a... |
