VRAC: Theory #1

摘要:

为了充分利用为传感器网络开发的地理路由技术,节点必须本地化。然而,传统的定位和虚拟定位技术要么依赖于昂贵的且有时不可用的硬件(例如GPS),要么依赖于复杂的定位演算(例如三角测量),这两者都容易出错并且具有昂贵的开销。我们不是在物理二维欧几里得空间中实际定位节点,而是直接使用到一组锚的原始距离来产生多维坐标。我们证明了物理二维欧氏空间的图像是一个二维表面,我们表明,它是可以适应地理路由策略在这个表面上,简单,有效和成功。

英文摘要:

In order to make full use of geographic routing techniques developed for sensor networks, nodes must be localized. However, traditional localization and virtual localization techniques are dependent either on expensive and sometimes unavailable hardware (e.g. GPS) or on sophisticated localization calculus (e.g. triangulation) which are both error-prone and with a costly overhead. Instead of actually localizing nodes in the physical two-dimensional Euclidean space, we use directly the raw distance to a set of anchors to produce multi-dimensional coordinates. We prove that the image of the physical two-dimensional Euclidean space is a two-dimensional surface, and we show that it is possible to adapt geographic routing strategies on this surface, simply, efficiently and successfully.
