摘要:

超宽带脉冲无线电(IR-UWB)是解决无线传感器网络(WSN)约束的一种很有前途的技术。然而,现有的网络仿真工具并没有提供一个完整的无线传感器网络仿真架构,在物理层(PHY)和介质访问控制(MAC)层的IR-UWB特性。在本文中,我们提出了一个无线传感器网络的仿真架构的基础上IR-UWB技术。在物理层,我们通过处理脉冲传播延迟来考虑脉冲碰撞。我们还模拟了MAC协议特定的IRUWB,无线传感器网络的应用。为了完全符合无线传感器网络仿真的要求,我们提出了一个通用的和可重用的传感器和传感信道模型。大多数的无线传感器网络的应用性能可以评估感谢所提出的模拟架构。所提出的模型上实现了一个可扩展的和众所周知的网络模拟器:全球移动信息系统模拟器(GloMoSim)。然而,它们可以被重用于所有其他基于分组的仿真平台。

英文摘要:

Impulse Radio Ultra Wide Band (IR-UWB) is a promising technology to address Wireless Sensor Network (WSN) constraints. However, existing network simulation tools do not provide a complete WSN simulation architecture, with the IR-UWB specificities at the PHYsical (PHY) and the Medium Access Control (MAC) layers. In this paper, we propose a WSN simulation architecture based on the IR-UWB technique. At the PHY layer, we take into account the pulse collision by dealing with the pulse propagation delay. We also modelled MAC protocols specific to IRUWB, for WSN applications. To completely fit the WSN simulation requirements, we propose a generic and reusable sensor and sensing channel model. Most of the WSN application performances can be evaluated thanks to the proposed simulation architecture. The proposed models are implemented on a scalable and well known network simulator: Global Mobile Information System Simulator (GloMoSim). However, they can be reused for all other packet based simulation platforms.
