| 摘 要： | 为降低无线传感器网络的定位误差,提高动态节点的定位精度和定位覆盖度,使节点定位能够应用于动态环境下,基于传统的定位算法,提出了一种新的动态节点定位改进算法。该算法通过未知节点接收、保存的分组信息来循环组成虚拟三角形,同时依靠内点测试方法来判断未知节点自身位置,最后根据质心算法来进行最终定位。将仿真结果与传统算法进行比较,结果表明,改进算法可以大大提高无线传感器网络的定位精度和覆盖度。

| Abstract: | To reduce the localization error of wireless sensor networks,and improve the accuracy and coverage of dynamic node localization,an improved algorithm of the dynamic node localization based on traditional localization algorithm is proposed,which make the node localization is used in dynamic environment.The proposed algorithm relies on the grouping of information received and saved by the unknown node,then the virtual triangle is composed,at the same time using the in testing method to judge the position of t... |
