摘　　要：多跳定位算法大多假定节点分布的环境无障碍物,在实际环境中,节点分布的场景通常较为复杂,网络拓扑常呈现不规则,造成用跳数估算距离发生严重偏差。该文提出了一种基于信息准则的多跳无线定位方法。该方法在信息准则的帮助下构建锚节点间最优的映射模型,并以该映射模型来预测未知节点到锚节点间的估计距离。通过理论分析和实验验证,该文提出的算法在不规则网络中具有定位精度高、计算复杂度低和定位速度快的优点,有较广泛的使用价值。Most previous localization algorithms assume that the network is uniform and has not holes or obstacles.Networks may be irregular with obstacles in practice,which makes the shortest path deviate the geographical distances.In this paper,an information criterion-based wireless multi-hop localization algorithm is proposed.With the help of information criterion,this algorithm constructs the optimal mapping model between anchor nodes and uses the mapping model to predict the estimated distance between the unknown nodes and the anchor nodes.The theoretical analysis and experimental results show that the proposed algorithm has not only high localization accuracy but also low computational complexity and fast running-speed in irregular networks,having a wide range of use-value.
