| 摘 要： | 环境和硬件本身等因素使无线传感器网络的定位精度受到影响。为此，通过三维空间定位过程的分析，提出基于接收信号强度(RSSI)测距和Gauss模型的RGM定位算法。该定位算法无需硬件的扩展。仿真实验表明，相比普通的基于RSSI的测距算法，该算法可提高定位精度、缩短响应时间。

| Abstract: | The precision of the localization is affected due to the various reasons such as environment and hardware itself. The paper presents the Received Signal Strength Indicator（RSSI） ranging and Gauss Mixed（RGM） algorithm localization algorithm, which is based on RSSI range measurement and Gauss model. The algorithm is easy to implement and does not need to hardware extension. Simulation result shows that the proposed method obtains a more accurate localization result than the RSSI localization algorithm and has a shorter responding time. |
