基于改进的平均跳距和估计距离的DV-Hop定位算法
DV-Hop localization algorithm based on improved average hop distance and estimate of distance
摘要
Abstract
According to DV-Hop localization algorithm's deficiencies, put forward an inproved algorithm based on average hop distance and estimate of distance in order to enhance the accuracy of DV-Hop algorithm in the irregular network. In this improved algorithm, it considered the feature of coincidence or part of the overlap which existed in the path from unknown nodes to beacon nodes and the path between the beacon nodes, it improved average hop distance and used the error to correct distance. Results of the simulation show that the improved algorithm has a better performance than the original algorithm in positioning accuracy at the irregular network environment.关键词
