传感器网络自身定位方法的设计与实现

传感器网络是集无线通信、数据采集和信息处理功能于一体的新兴的分布式自组织数据采集网络,在军事和民用领域中都有着广泛的应用前景。传感器节点在被布置在目标区域之后,多节点协调的自身定位是应用阶段的基础。论文基于Mica2系统,研究利用电磁波与声波传播时间差(TDOA)进行测距,利用几何关系的自身定位算法设计与硬件实现。

Design and Implementation of Self-Localization Method for Wireless Sensor Networks

Sensor networks,which have integrated the wireless communication,data collection and information processing capacities are booming technologies for collecting information in distributed and self-organized manner.They are pro-mised for a wide range of applications for military and civilization.After the deployment of the sensor nodes,sensors localize themselves by coordination,which is the fundamental of various applications.Focusing on Mica2 system,we have studied the time difference of the radio signal and the sound wave(TDOA);discussing the ranging method,the geometry based self-localization methods and the implementation on Mica2 system.
