非均匀网络中半径可调的ARDV-Hop定位算法
ARDV-Hop Localization Algorithm with Adjustable Radius in Non-Uniform Networks
摘要
Abstract
For the problem of large localization error caused by uneven distribution of nodes in traditional DV-Hop(Distance Vector Hop)localization algorithm in wireless sensing networks,an ARDV-Hop localization algorithm with adjustable radius in non-uniform networks is proposed.The number of hops between nodes is refined by means of adjustable radius,the traditional integer-level hops are replaced with fractional-level hops after refinement,and a data energy consumption model is established to optimize the network transmission perform-ance.A hop distance optimization algorithm is also proposed for regions with uneven node distribution,i.e.,in regions with high node den-sity,the cosine theorem is used to optimize the hop distance,and in regions with low density,the minimum mean square error(LMS)is used to optimize the hop distance.Simulation experiments show that the ARDV-Hop algorithm can reduce the localization error more effec-tively than the traditional DV-Hop algorithm,GDV-Hop algorithm and WOA-DV-Hop algorithm under the same network environment.关键词
