在现有的移动的ad-hoc网络（MANET）的文献中，绝大多数的仿真研究，调查路由协议的性能使用一个简单的无线电信道模型，基于一个双射线地面反射路径，并忽略了快速和缓慢的衰落。报告的结果是从第一阶段的调查使用一个更现实的信道模型，其中包括通常发现在室外和室内移动的无线电信道的慢（对数正态）衰落。结果的意义在于，它们表明以前的论文可能大大低估了无线电路径损耗，从而高估了特定路由协议的性能。
In the existing mobile ad-hoc network (MANET) literature the vast majority of simulation studies that investigate routing protocol performance use a simplistic radio channel model, based on a two-ray ground-reflected path, and ignore both fast and slow fading. Reported are results from the first phase of an investigation into the use of a more realistic channel model, which incorporates the slow (lognormal) fading typically found in both outdoor and indoor mobile radio channels. The significance of the results are that they show previous papers may have significantly underestimated the radio path loss, thereby overestimating the performance of particular routing protocols.
