基于无线电相干的传感器网络节点定位

目前无线传感器网络节点定位算法中，能够兼顾高精度和远距离定位的算法只有RIPS方法，然而该方法利用汇聚节点进行集中定位。提出了一种基于无线电相干的角度估计算法，并分布式定位节点，在高精度、远距离定位节点的同时，可大规模应用该算法，且定位速度快。实验表明，该方法平均方位估计误差是3.20，90%的测量值误差在6.4度以内。

Node localization in sensor networks based on wireless coherent

At present,wireless sensor network node positioning algorithm,capable of both high precision and long distance positioning algorithm only the RIPS method, however,the sink node centralized location. An estimation algorithm is proposed based on the perspective of radio interference,and distributed node localization,in the high accuracy, remote location nodes at the same time,large-scale application of the algorithm,and the positioning speed. Experiments show that,the average estimation error is 3.20,90% of the measurement error in 6.4 degrees.
