一种网络跳距修正的分布式定位算法研究
A Distributed Localization Algorithm with Correction in Hop Distance of the Network
摘要
Abstract
The error of conventional DV-Hop localization algorithm comes from the average hop distance. In response to this problem,an improved algorithm was proposed. In this improved algorithm,the effective distances between an unknown node and all anchor nodes were obtained through introducing the value of error correction about the average hop distance of the whole network,and it effectively avoided error accumulation in subsequent calculation. Simulation results show that with the increasing of the anchor node density, the improved algorithm has been improved effectively in localization accuracy, stability and coverage with a small numbers of calculations based on no further communication resource.关键词
