摘要

基于接收信号强度指示（RSSI）的测距技术是一项低成本和低复杂度的距离测量技术

被广泛应用于无线传感器网络基于距离的定位技术中。由于室内环境下存在非视距和多径传输的影响

测距误差比较大。在消除测距误差的方法中

采用线性回归分析对射频参数A和信号传输常数n进行优化

得到满足具体环境的参数值。提出2种滤波模型对采集的RSSI进行滤波处理。实验表明:通过参数优化和滤波处理

测距精度得到了明显的提高。

Abstract

Distance measurement technology based on RSSI is a low-cost and low complexity distance measurement technology.It is widely applied in the range-based localization of the wireless sensor networks.Because of non line of sight and multipath transmission effects under the indoor environment

the ranging error is relatively large.In the method of eliminating ranging error

linear regression analysis is used on the RF signal transmission parameters A and n to optimize the constants and obtains parameters to meet specific environment.Two kinds of filtering model for filtering collected RSSI is proposed.The experimental results show that ranging error has been significantly improved through parameter optimization and filtering processing.
