摘要 该文简要分析了DV-hop算法的定位原理,在分析锚节点比例、节点部署密度对该算法定位精度影响的情况下,针对稀疏的随机无线传感器网络引入移动锚节点。移动锚节点使用一种在自组织网络中经常用到的移动模型。仿真结果表明,改进的M-A-DV-hop算法很大程度地降低了硬件成本,并显著提高了算法在稀疏随机传感网中的定位精度。 In this paper we briefly analyze the theory of DV - hop algorithm. The anchor node ratio and the node deployment density affect the localization precision in random wireless sensor networks. Then we introduce mobile anchor nodes when the network has sparse nodes. The mobile anchor nodes use the random way point（RWP） mod- el, which is widely used in the Ad Hoc networks. The simulation results demonstrate that the mobile anchor nodes greatly reduce the hardware cost and distinctly improve the localization precision.
