| 摘 要： | 大规模水下传感器网络覆盖范围广,监测深度大,基于静止信标的定位方法很难获得好的定位性能。提出一种基于移动信标的range-free定位方法,信标在上下移动过程中广播位置信息,节点利用信标信息的变化估计位置范围。移动信标增大了网络覆盖范围,降低了节点间通信距离。实验结果表明,该方法可以获得和多功率发射定位接近的定位精度,但系统代价更低,精度高于一般的range-free定位方法。

| Abstract: | There are lots of difficulties for large scale underwater sensor networks to achieve perfect localisation performance using the localising approach based on static beacons,since the networks cover a great deal of wide areas and inspect in big depth.In this paper the authors propose a new range-free localisation method based on mobile beacons.The beacons broadcast their position information when moving upwards and downwards,and the nodes estimate the range of positions by the variation of beacons' informatio... |
