摘要 针对无线传感器网络中DV-Hop定位算法在未知节点到信标节点距离计算中的不足,提出了一种改进算法。该算法考虑了未知节点到信标节点路径中相邻三个节点A,B,C组成的夹角∠ABC对距离的影响,根据与B相邻的A,C节点的邻节点集重叠度估算夹角的大小,从而更精确计算出距离,提高定位精度。 To overcome the disadvantage of DV-Hop algorithm when it was used to compute the distance of unknown nodes and beacon nodes in the wireless sensor network, an improved algorithm was proposed. In this improved algorithm, the distance of unknown nodes and beacon nodes was computed, using the angle ∠ ABC formed by three neighbor nodes A, B and C in the path of unknown nodes and beacon nodes, and given distance data among the nodes. This angle L ABC was estimated with an overlapping degree of B＇s neighbor node sets collecting with A and C, respectively. The experimental results show that the improved algorithm has more accurate locating compared with DV-Hop algorithm.
