摘　　要：作为一种全新的信息获取和处理技术,无线传感器网络可以在广泛的应用领域内实现复杂的大规模监测和追踪任务,而网络自身定位是大多数应用的基础.介绍了无线传感器网络自身定位系统和算法的性能评价标准和分类方法,着重综述了近年来该领域具有代表性的算法及系统的原理和特点,并指出未来的研究方向.Wireless Sensor Networks, a novel technology about acquiring and processing information, have been proposed for a multitude of diverse applications. The problem of self-localization, that is, determining where a given node is physically or relatively located in the networks, is a challenging one, and yet extremely crucial for many applications. In this paper, the evaluation criterion of the performance and the taxonomy for wireless sensor networks self-localization systems and algorithms are described, the principles and characteristics of recent representative localization approaches are discussed and presented, and the directions of research in this area are introduced.
