摘要

首先分析无线传感器网络(WSN)中基于RSSI(接收信号强度指示)的现有定位算法存在的不足

然后在不同时间和空间的大量实验数据基础上

结合丢包率和RSSI提出了针对实际环境的距离评估模型和建立在此模型基础上的无线传感器网络定位算法

以此作为对无线定位研究的一种新的探索。通过实验对算法性能进行评估

证明使用该算法的WSN能够正常定位并具有较高的定位精度和稳定性。

Abstract

First

the shortcoming of existing location algorithm based on RSSI（received signal strength indication） in WSN（wireless sensor network） was analyzed.Then

supported by plenty of experimental data in different time and space

the distance evaluation model combining with packet lost rate and RSSI which aim at real environment and location algorithm based on this model was provided.It was regarded as a new kind of exploration for research of wireless location.Location experiments were used to evaluate the capability of this algorithm

which proves that WSN nodes running this algorithm can normally work and precision and stability are upper.
