中文摘要：
提出一种协作定位方法.利用邻居信标交互,获取定位环境信息,并在此基础上实现基于无效信标过滤的信号强度定位.同时,在多种定位方法协作判定下,将精度较高的已定位节点升级为信标节点.仿真结果表明,该方法同加权RSSI及APIT定位方法相比,具有较高的定位精度和定位成功率.
英文摘要：
A cooperating localization algorithm is proposed.Environmental information is obtained with the help of neighbor beacon interaction and node′s location could be obtained based on invalid beacon filtration as well as the signal strength detection.Furthermore,in collaboration with a variety of localization methods,node with higher localization accuracy becomes beacon.Simulation results demonstrate that this algorithm performs well on localization accuracy as well as success rate compared with the weighted RSSI and APIT algorithm.
