摘要: 网络自身定位问题是无线传感器网络的基本和重要问题之一。由于rangebased定位机制的局限性,无需配置测距或测角设备,硬件成本低的距离无关定位算法被提出。根据是否有无锚节点来论述和比较现有的距离无关定位算法,提出距离无关定位算法需进一步研究解决的问题。

Abstract: Node localization is a fundamental and crucial issue for Wireless Sensor Network (WSN). In view of the limitations of rangebased techniques, rangefree localization scheme is proposed. Existing rangefree localization approaches are discussed and presented in detail, and the performance of them are compared. Finally, future works in the field of rangefree localization algorithm are pointed out.
