摘要

RSSI测距技术在实际应用环境中

由于多径、绕射、障碍物等因素

无线电传播路径损耗使得定位过程中产生距离误差。通过对三维空间定位过程中产生距离误差区域进行分析

提出了基于RSSI新的空间定位算法ERSS

该定位算法计算简单

定位过程中节点间不增加通信开销

无需硬件扩展。仿真实验表明该算法较普通的基于RSSI的测距方法定位精度和响应时间有了明显的改进

适合在通信开销小、硬件要求低的传感器网络节点上应用。

Abstract

In real measurement environment

some factors of multi-path

diffraction

obstacles

etc.

propagation losses produced location errors in the positioning process by RSSI technology.Through analyzing error range in 3D space

a new spatial locating algorithm ERSS based on RSSI was proposed.The ERSS algorithm had the advantages: locating calculation simplicity

no extra communication cost on the locating process

and no hardware expansion required.Simulation results show ERSS algorithm achievs noticeable improvement over RSSI algorithm on distance locating accuracy and responding time

and it is suitable to be applied on the environment of wireless sensor network nodes with low cost and performance of hardware.
