| Abstract | TP393; 为提升DV-Hop(distance vector-hop)算法定位精度水平,提出一种基于割圆术的DV-Hop全局优化(circle-cutting technique for global optimization of DV-Hop algorithm,CTGO-DV-Hop)算法.该算法精确了最小跳数,引入权值模型对全部锚节点的平均单跳距离进行优化,并采用加权最小二乘递推算法对未知节点坐标进行拟合.实验测试多种因素对于算法的影响,结果表明,所提出的 CTGO-DV-Hop算法表现出良好的性能,相较于 DV-Hop、OCSLC-DV-Hop和WOCS-DV-Hop,平均定位误差的最大降幅为70％左右,适用于构建节点数目大、锚节点比例低的无线传感器网络系统. |
