改进的DV-Hop定位算法研究
Research on Improved DV-Hop Localization Algorithm
摘要
Abstract
Only the average one-hop distance estimated by the nearest anchor is used in DV-Hop localization algorithm, but the value estimated by a single anchor can not reflect the whole network's actual average hop distance. A novel algorithm is proposed to estimate the average hop distance based on weighted disposal. The average hop distance estimated by several anchors is used in this algorithm and assigned different weights according to the hops and the environmental impact factors to the unknown node. The unknown node's average one-hop distance is estimated more accurate and the localization precision is improved. Simulation results demonstrate that the average hop distance is estimated more exactly in the proposed algorithm than that of DV-Hop, and the location precision is improved.关键词
