| 摘 要： | 为解决无线传感器网络中现有序列定位算法存在的定位精度差、复杂度较高等问题,本文提出一种基于虚拟锚节点的序列定位算法。该算法根据未知节点与已有锚节点、虚拟锚节点(锚节点间连线的中点)间的RSSI值建立定位序列来获取未知节点的位置。仿真结果表明,基于虚拟锚节点的序列定位算法比原有算法在定位精度上有较大提高,且降低了算法的硬件代价和时间代价。

| Abstract: | For the purpose to find a solution to lessen the algorithmic complexity of newly proposed sequence-based localization algorithm,a novel algorithm based on virtual anchor nodes is proposed.This method can reduce the amount of classifications for referential anchor nodes through establishing virtual anchor nodes.Accordingly,it can cut time consumed for positioning.Computer simulation indicates that the new method is more accurate than sequence-based localization algorithm and it can take less time for positioning. |
