摘要

文献中广泛采用自由空间模型和双射线地面反射模型作为研究自组网性能的传播模型。但这两个模型过于简单，无法代表真实世界的场景。本文采用一种更为实际的模型——阴影传播模型来研究自组织网络的性能。在遮蔽传播模型中，移动节点可以在低于所需阈值水平的信号水平上接收数据包。这种低信号电平影响路由协议，也影响网络的介质访问控制方案。本文研究了阴影对自组网性能的影响。本文还提出了两种解决方案来克服阴影的影响。

Effects of Shadowing on the Performances of Mobile Ad Hoc Networks

Free-space model and two-ray ground reflection model have been widely used in the literatures as the propagation models to investigate the performance of an ad hoc network. But these two models are too simple to represent a real world scenario. A more realistic model namely shadowing propagation model has been used in this paper to investigate the performances of ad hoc network. In shadowing propagation model a mobile node may receive a packet at a signal level that is below a required threshold level. This low signal level affects the routing protocol as well as the medium access control scheme of a network. In this paper, the effects of shadowing on the performance of an ad hoc network have been investigated. Two solutions have also been suggested in this paper to overcome the effects of shadowing.
