K-栅栏覆盖是有向传感器网络覆盖控制的研究热点之一。提出一种基于邻居节点运动的有向强栅栏构建算法（NS-DBC）。在形成栅栏的节点集合中，按照从左到右的节点顺序，依次确定每一个节点的目标位置，前一个节点确定后一个邻居节点的目标位置，后一个节点的选取仅与前一个节点有关。后一个节点从前一个节点附近节点中选择能耗最少的节点运动到目标位置，从而构建有向强栅栏。仿真结果证明了该栅栏构建方法能够用较低能耗和较少节点构建有向栅栏。本文的研究对提升无线传感器网络的性能具有重要的理论与实际意义。

K-barrier coverage is one of the hot spot in directional wireless sensor network. This paper proposes a dis?tributing directional strong barrier construction scheme based on next node sports(NSDBC)to create directional bar?rier coverage with lower energy consumption. It is only the previous node that determines the next target node posi?tion for barrier;the target node position is constituted by the coordinate of center and working direction of sensing sector. The previous node finds node in its vicinity that moves to target next node location with minimum moving en?ergy consumption and adjusts its working directional to target direction with minimum rotating energy consumption. Simulation results show this method could effectively constitute K-barrier coverage,and enhance the coverage per?formance of DSN. This research has important theoretical and practical significance.
