在Bounding-box及其改进方法研究中，普遍采用正方形的重叠区域的质心作为定位的结果，然而该正方形与实际无线传感器节点的通信区域模型之间存在较大差异，导致定位误差较大。针对此问题，提出一种改进的Bounding-box定位方法。该方法在定位时，不再采用正方形的通信区域模型，而是采用圆形的通信区域模型进行定位。基于仿真数据以及采用3种典型通信环境下真实的到达信号强度指示（ received signal strength indicator，RSSI）数据完成定位实验，实验结果表明，该方法具有较高的定位精度，因此具有一定的实际应用价值。

The centroid of the overlapped area of a square is generally taken as the result of localization when utili-zing the Bounding-box localization and its improvement methods.However, there exists a big difference between the square and the real communication range model of the wireless sensor node, which leads to a large localization er-ror.In this paper, a newly improved Bounding-box localization method is proposed.In this method,a circular model is adopted for localization in Bounding-box method instead of the communication range model of the square.The ex-perimental results based on simulations and the real received signal strength indicator( RSSI) values in three typical environments showed that the new method may realize high localization accuracy and has actual application value.
