摘　　要：节点定位技术是无线传感器网络中的关键技术之一。为了提高节点定位精度,在DV-HOP算法的基础上提出两种改进措施:锚节点规划部署和加权算法,改进后的算法统称为加权DV-HOP。在新算法的基础上建立Matlab仿真模型。仿真结果表明加权DV-HOP算法,在相同的锚节点数量和锚节点无线覆盖范围下,节点定位精度约提高10%。The location information of the sensor node is one of the key technologies in Wireless sensor network（WSN）.This paper proposes two improvements based on the DV-HOP algorithm：the anchor placement strategy and the Weighted AHS algorithm,named as Weighted DV-HOP.A Matlab simulation model based on the Weighted DV-HOP is established.The results show that the proposed algorithm improves node location accuracy by more than 10% with same amount of anchor nodes under same radio range condition.
