基于射频识别和无线传感网融合技术的仓储定位方法研究
Research on warehouse localization method based on integration of RFID and WSN
摘要
Abstract
For the large number of nodes and the small effective coverage area in radio frequency identification(RFID) localization in large scale storage location environment,this paper proposed a twice localization algorithm based on the mobile anchor node.Traditional centroid algorithm can only effectively locate the nodes with 3-degree coverage,resulting in the waste of nodes.Integrated a fusion of RFID and wireless sensor network(WSN) technology,this paper constructed a new anchor node.It divided the anchor node in the traditional positioning process into fixed ones and mobile ones.It used the fixed anchor node to locate an initial position,and used the localization vector to determine the stop position of the mobile anchor node.Finally,it used a weighted centroid localization algorithm based on signal strength for the secondary accurate localization.Simulation experiments show that the proposed method can effectively reduce the number of anchor nodes,and make up the localization effect of the incomplete area of the RF signal coverage,and improve the localization accuracy and coverage.This method has certain actual application value.关键词
