VRAC:模拟结果#1

VRAC: Simulation Results #1

Florian Huc, Aubin Jarry

摘要:

为了充分利用为大规模网络开发的地理路由技术,节点必须本地化。然而,传感器网络中的定位和虚拟定位技术要么依赖于昂贵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),这两者都容易出错且开销昂贵。而不是在传统的二维空间中定位节点,我们直接使用到一组锚的原始距离在多维空间中路由消息。这将使我们能够在非常广泛的场景中以健壮和有效的方式使用任何地理路由协议。我们测试这种技术的两个不同的地理路由算法,即GRIC和ROAM。仿真结果表明,使用原始坐标不会降低其效率。

英文摘要:

In order to make full use of geographic routing techniques developed for large scale networks, nodes must be localized. However, localization and virtual localization techniques in sensor networks 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 localizing nodes in a traditional 2-dimensional space, we use directly the raw distance to a set of anchors to route messages in a multi-dimensional space. This should enable us to use any geographic routing protocol in a robust and efficient manner in a very large range of scenarios. We test this technique for two different geographic routing algorithms, namely GRIC and ROAM. The simulation results show that using the raw coordinates does not decrease their efficiency.
