摘　　要：研究基于RSSI的Wi-Fi直连架构下的测距模型及其修正以实现对不可视区域未知设备的空间定位。分析IEEE802.11相关协议,设计无线Wi-Fi直连方案。分析基于RSSI的距离测量模型,并对其进行相应的修正。由至少三个己知的Wi-Fi直连设备接收来自同一个不可视区域的未知Wi-Fi直连设备得到的RSSI估计出距离,结合几何学原理实现对该设备的立体空间定位。Research of distance measurement model and its amendments in Wi-Fi Direct architecture based on RSSI is to achieve spatial orientation of an unknown device of the non-visible area. Analysing IEEES02.11, desig- ning program of Wi-Fi Direct. Distance measurement model is analysed based on RSSI amending it. The RSSIs ob- tained by at least three known Wi-Fi Direct device from the same unknown Wi-Fi Direct device of a non-visible area are estimated the distance, to achieve three-dimensional spatial orientation of the device combined with the geometry.
