摘　　要：通过对无线传感器网络RSSI定位和Zigbee网络指纹数据库的研究,本文利用指纹数据库计算用户坐标位置,提出利用高斯滤波对Zigbee网络指纹数据库进行信息采集和优化,在定位阶段对数据进行高斯滤波处理,从而建立高精度的指纹数据库。结果表明:利用Zigbee指纹数据库实现短距离范围内定位效果较好,而且在优化指纹数据库后再进行定位时,定位精度显著提高。Through the research of the wireless sensor network RSSI localization and Zigbee network fingerprint database,the user coordinate location was calculated with fingerprint database in this paper,a method was proposed to achieve the information acquisition and optimization of Zigbee network fingerprint database with Gauss filter in the positioning stage to establish the high precision fingerprint database.The results show that there was a better result in the short range positioning with Zigbee fingerprint database,and the positioning accuracy was improved significantly with the optimization of the fingerprint database.
