提出了一种基于移动的信标和地图配准算法的无线传感器网络定位方法。定位系统由一个移动的信标和信标接收模块在每个传感器节点。在传感器节点部署阶段使用移动的信标获得节点间距离。地图配准算法使用节点间的距离测量来估计传感器节点的位置。该算法能够提高稀疏网络和不规则拓扑网络的定位性能。提出的定位方法是一种无GPS解决方案，这使得它对于无法使用GPS访问的应用程序具有吸引力。计算机仿真被用来评估所提出的方法在不同的场景下的定位性能。
In this paper, a new sensor localization approach is presented, which is based on the use of a mobile beacon and a map registration algorithm for wireless sensor network applications. The localization system consists of a mobile beacon and beacon receiving modules on each sensor node. Internode distances are obtained during the stage of sensor node deployment using the mobile beacon. The map registration algorithm uses inter-node distance measurements to estimate the sensor node locations. The algorithm is able to improve localization performance for sparse networks and networks with irregular topology. The proposed localization approach is a GPS-less solution, which makes it attractive for applications where GPS access is not available. Computer simulations are used to evaluate the localization performance of the proposed approaches under different scenarios.
