摘　　要：以二维平面为例,构建了DV-HOP无线传感器节点定位模型,将其转化为多约束下的极值求解问题。采用海洋捕食者算法(MPA)求解该极值问题,获得未知节点的坐标信息,实现节点的智能定位,并将MPA-DV-HOP、GA-DV-HOP、DV-HOP应用于仿真试验中,对比三种算法对节点的定位性能。结果表明,MPA-DV-HOP相对于其它两种算法具有节点定位稳定性强、定位精度高优势,且增大通信半径和节点总数能够在一定程度上达到提高节点定位精度的目的。Taking a two-dimensional plane as an example,a DV-HOP wireless sensor node localization model is constructed and transformed into an extremum solution problem under multiple constraints.MPA is used to solve the extreme value problem,and the coordinate information of the unknown node is obtained,and the intelligent positioning of the node is realized.positioning performance.The results show that MPA-DV-HOP has the advantages of strong node positioning stability and high positioning accuracy compared with the other two algorithms and increasing the communication radius and the total number of nodes can achieve the purpose of improving the node positioning accuracy to a certain extent.
