| 摘 要： | 针对无线传感器网络中DV-Hop定位算法锚节点数的比例与节点定位精度以及覆盖率密切相关的问题,在分析原算法的基础上对其进行改进。改进后的算法未知节点只接收限定跳数内的锚节点的信息,当未知节点接收到3个或3个以上锚节点的信息时对其进行定位,然后将已定位的未知节点升级为锚节点,新旧锚节点共同参与剩下的未知节点的定位。仿真结果表明改进后的算法提高了节点的覆盖率和定位精度。

| Abstract: | Because the scale factor of anchor nodes is closely related to both node localization accuracy and coverage rate in DV-Hop location algorithm for wireless sensor networks,an improved DV-Hop(iDV-Hop) localization algorithm is proposed in the paper through analyzing the DV-Hop location algorithm for improving the location accuracy and coverage rate.Unknown nodes only receive information of anchor nodes with limited hops in iDV-Hop localization algorithm.When a unknown node receives more than 3 anchor nodes,th... |
