| 摘 要： | 针对无线传感器网络传统目标定位过程中，数据在大量传感器节点间传输使得节点能量迅速耗尽，同时远距离低信噪比节点对定位精度的影响等问题。基于分区域协同工作的思想，提出了一种协同源定位算法。对该算法进行仿真试验，结果显示，该算法明显降低了网络能耗，且具有较高的定位精度和稳健性。

| Abstract: | In wireless sensor network localization, the raw data is transmitted among a mass of sensor nodes, and the energy of node is exhausted rapidly. Meantime, low SNR nodes will influence the precision of localization. In order to solve these problems, based on several divided regions collaboration, a collaborative source localization algorithm is presented. The simulations show that the proposed algorithm can reduce the energy consumption dramatically, and this algorithm is accurate and robust. |
