一种基于测距的无线传感器网络智能定位算法

An Intelligent Localization System Based on RSSI Ranging Technique for WSN

提出了一种基于测距的无线传感器网的智能定位算法。建立了RSSI的理论计算模型;通过引入加权因子改进了DV-Distance定位算法(IDV-Distance)。实验结果表明:改进后的定位算法提高了定位精度,改善了系统的稳定性。

An intelligent localization system based on RSSI for WSN is proposed. A RSSI（Received Signal Strength Indicator） model is established based on the study of RSSI theoretical model, and DV-Distance algorithm is improved by adding in weighted factors, which is completed on TinyOS. It is proved by practical experiment that the improved DV-Distance has the advantage of precision and stabilization than the standard DV-Distance, so it is appropriate to apply to wireless sensor networks.
