无线传感器网络中DV-Hop定位算法的改进
Improved DV-Hop localization algorithm in Wireless Sensor Network
摘要
Abstract
In view of the positioning process of the traditional DV-Hop localization algorithm, the insufficient estimation of average hop distance between anchor nodes and unknown nodes that appear in the process of the localization and the unknown node coordinate beyond the existing bound of a given area, this paper proposes an improved DV-Hop(Distance Vector-Hop)localization algorithm. In the improved algorithm, the average hop distance is compensated, and the coordinates of the unknown nodes of beyond location area are corrected. The simulation results show that the improved DV-Hop algorithm is more accurate to estimate the average hop distance, effectively reducing the positioning error of the unknown nodes.关键词
