摘要

近年来，无线传感器网络(WSN)越来越普及，WSN的定位问题引起了人们的广泛关注。在非视距传播条件下，由于移动站与基站之间的建筑物阻碍了波的传播，定位精度低于视距传播条件下的定位精度。为了使定位更加准确，本文提出了一种基于Rwgh算法的改进方法来减小NLOS误差。该方法的基本思想是逐步消除非视线传输情况，然后在LOS传播环境中进行定位。仿真结果表明，与其他定位方法相比，该方法具有更好的定位精度。

A NLOS selection based localization method for wireless sensor network

In recent years, the wireless sensor network (WSN) has become more and more popular, and the problem of WSN localization has attracted great attention. In non-line of sight (NLOS) propagation conditions, the localization is less accurate than in line of sight (LOS) propagation conditions because of the buildings between the mobile station and the base station obstruct the spread of waves. In order to make the location more accurate, in this paper, we propose an improved method to reduce the NLOS error based on Rwgh Algorithm. The basic idea of this method is to gradually eliminate the non-line of sight transmission situation, then positioning in the LOS propagation environment. According to the simulation result, this kind of method has better localization accuracy when compared with other methods.
