摘要: 针对无线传感器网络中未知节点分布不均的问题,提出了一种无线传感器网络自适应定位算法。首先通过遍历未知节点,对区域密度进行划分,自适应改变各个区域信标节点虚拟力系数,使得信标节点合理分布于被监测区域中,提高了定位精度。理论分析和实验表明:算法是行之有效的。

Abstract: According to the uneven distribution of the unknown node in wireless sensor networks,a new self-adaptive localization algorithm in Wireless Sensor Networks is proposed.In order to get a reasonable distribution of beacon node,this paper divides the area by traversal the unknown beacon,then changes the virtual force coefficient of beacon node.The location accuracy is improved by this algorithm.The theory analysis and experimental results show the feasibility and effectiveness of the algorithm.

Key words: Wireless Sensor Networks(WSN), self-adaptive localization, mobile beacon
