摘　　要：针对移动无线传感器网络定位安全性的问题,分析了虫洞攻击对MCB方法的影响,在MCB的基础上提出了一种安全定位算法DWMCB。在锚节点存在虫洞攻击的情况下,该算法通过计算当前定位节点可检测到的锚节点组成多边形的质心以及几何关系,识别并剔除伪锚节点。仿真结果表明,DWMCB算法在受到虫洞攻击的网络中能够提高节点定位的精度。To solve the problem of secure localization in mobile wireless sensor networks, this pap e r analyzes the effect of wormhole attack onMCBmethod, and then proposes a secure localization algorithm DWMCB. In case that anchor nodes are under worm attack,this algorithmidentifies and eliminates the false anchor node information by calculating the centroid of the polygon of detected and the geometric relationship. The simulation results show that the secure localization algorithim can tion in wireless sensor networlss which are under wormhole attack.
