一种传感器网络高精度定位系统:设计与仿真
High precise location system for WSNs: design and simulation
摘要
Abstract
A novel location method based on phase differences of multiple arrival signals is proposed, in consideration of the special application scenarios. In this method, the target node sends FM modulation signal, and the anchor node obtains the arriving time differences of the received signal by measuring their phase differences, and then locates the target node by TDOA algorithm. On this basis, the location system and the position process are introduced. By means of software System View, system simulation is conducted. The distance measurement module and positioning accuracy of this system are analyzed in detail. The investigation validates the proposed location method, and demonstrates better suitableness for the special application scenario compared with other existing position systems.关键词
