| 摘 要： | 通过引入虚拟力导向的节点移动方式,将未知节点接收到锚节点信息的个数作为计算虚拟力的参数,提出了基于虚拟力的无线传感器网络多跳定位算法。算法继承了DV-Hop(distance vector-hop)定位成功率较高的特点,通过优化网络布局的方式,使得定位过程中校正值的估算和选取更为合理。指出了该定位算法的关键技术,并对其进行了仿真验证。仿真结果显示该算法能够显著地提高节点的定位精度,并能够有效地提高节点对传感区域的覆盖率。

| Abstract: | This paper proposes a multi-hops localization algorithm based on virtual force.The number of beacon messages accepted by unknown node was used as a parameter of the force calculation.The proposed algorithm inherits the advantage of DV-Hop.By optimizing the network distribution,the correction value is more reasonable.The key technology of this algorithm was pointed out.Simulation result shows that it can greatly improve the localization accuracy and the coverage of sensing area. |
