摘要
基于DV-Hop的无线传感器网络定位算法在洪泛过程中产生大量信息而导致能量消耗大的问题,提出了一种选择边界锚节点的算法。通过减少参与洪泛的锚节点个数来减少能量消耗,从而延长无线传感器网络的生存周期。实验表明,提出的算法不仅能够减少传递的信息量,而且还能略微提高定位精度。
This paper proposes a novel algorithm of selecting outer anchor nodes to address the problem that DV-Hop localization algorithm of wireless sensor networks produces so much information as to produce consumption-intensive.This method can lengthen the living cycle of wireless sensor networks by reducing the number of anchors participating in the flood process.The experiments results show that the proposed algorithm can both reduce the transferred information and slightly enhance the localization accuracy.
