RSSI及TOF测距技术及仿真研究

Research on RSSI and TOF Ranging Technology and Simulation

摘要:

无线传感器网络综合了嵌入式计算、传感器和通信等多种技术,可以实现对信息的获取与处理；借助其他辅助定位方式,可以实现对非合作目标的定位。而无线传感器网络测距技术是实现定位的基础。对TOF和RSSI这2种测距技术进行了深入的研究,比较这2种测距技术在不同范围内的测距效果,进而为工程应用提供理论基础。

Abstract:

Wireless sensor networks combine embedded computing technology, sensor and communication technology, can achieve the access and treatment of the information, and can finish the position of non-corporative target relying on other auxiliary position methods. The ranging technology of wireless sensor networks is the base of position, so in this paper, the two kinds of ranging technology, TOF and RSSI were deeply studied, and the ranging effect of the two methods in different range was compared, thus it could provide theoretic base for engineering application.
