摘要
DV-Hop算法适用于矿下节点分布不均匀的环境,现有对DV-Hop算法的改进大多数是为了减少定位过程中的误差。提出了一种在DV-Hop算法基础上用缩小定位范围的方法来提高定位精度的方法,该算法保留了DV-Hop算法节点间通信量少的优点,适合矿下的网络场景。仿真结果表明,改进后的算法大大提高了无线传感器网络节点的定位精度。
DV-Hop algorithm is applicable to the uneven distribution of the next node in the mine environment. Most of the existing improved DV-Hop algorithm in order to reduce the error in the positioning process, this paper proposes a new DV-Hop algorithm with narrow orientation range to improve the positioning accuracy. The algorithm retains the advantages of DV-Hop algo- rithm for less communication between nodes,which is suitable for the network scenarios in the mine. The simulation result shows that the improved algorithm can greatly improve the positioning accuracy of the unknown nodes in wireless sensor network.
