基于相交环的水下无线传感器网络节点自定位研究
Study for the Self-Localization Algorithms Based on the Intersect Rings in Underwater Wireless Sensor Networks
摘要
Abstract
In the underwater wireless sensor networks,it is difficult to obtain the unknown nodes with the one-hop localization method in sparse auchor nodes over the network area. Based on the analysis of the exited underwater localization algorithms,a new Intersect Rings 2-Hops localization scheme(IR2H)is proposed in this paper. The nodes are localized with two-hops and the localization region of unknown nodes is reduced by clipping the concentric rings. The simulation results show that,in extremely sparse anchor nodes network,the IR2H scheme can improve the localization performance and coverage rate of unknown nodes greatly.关键词
