摘要
为了有效抑制复杂环境对无线传感器网络节点定位精度的影响,以三边定位算法为基础,提出了一种锚节点加权补偿定位算法。该算法利用锚节点自身的定位功能,通过加权质心方法获得定位系统在锚节点附近的区域定位误差,并对该误差进行补偿,从而提高该区域盲节点的定位精度。实验结果显示,该算法简单有效,具有普遍应用意义。
In order to inhibit the influence of complex environment on the location precision of nodes in wireless sensor network effectively, an anchor node weighted location algorithm was given, based on the trilateration location algorithm. The algorithm uses the anchor node＇ s own positioning capabilities, and obtains the positio- ning error in the vicinity positioning system of the anchor nodes through the weighted centroid location algo- rithm to compensate for the errors, which enhance the positioning precision of blind nodes. Tests show that this algorithm is simple and effective, and can be used to many applications.
