为了在真实的世界中对移动自组网应用进行精确的评估，在无线网络仿真中需要真实的移动模型。在本文中，我们提出了一种新的方法来创建城市行人流（UPF）的流动性场景，再现行人在城市地区的步行行为。从给定的密度在几个点观察到的行人，我们的方法推导出一个UPF流动性的情况下，再现行人的步行行为与观察到的密度一致，使用线性规划技术。我们已经开发了一个网络模拟器EQUIPREAL设计和评估MANET协议和应用程序，这个现实的移动模型。EQUIPREAL提供了各种功能和工具，包括用于描述单个节点行为的移动模型，用于帮助自动生成UPF移动场景的GUI和可视化工具。我们已经进行了一些实验，使用的模拟器。通过实验，我们研究了节点移动性对MANET协议性能的影响，并显示了我们的方法和模拟器的实用性。
In order to perform precise evaluation of MANET applications in the real world, realistic mobility models are needed in wireless network simulation. In this paper, we propose a new method to create urban pedestrian flows (UPF) mobility scenarios, which reproduce the walking behavior of pedestrians in urban areas. From given densities of pedestrians observed at several points, our method derives a UPF mobility scenario that reproduces the walking behavior of pedestrians consistent with the observed densities, using linear programming techniques. We have developed a network simulator MobiREAL to design and evaluate MANET protocols and applications with this realistic mobility model. MobiREAL provides various functions and tools including a mobility model to describe the behavior of individual nodes, a GUI to assist with automatic generation of UPF mobility scenarios and a visualization tool. We have conducted some experiments using the MobiREAL simulator. Through the experiments, we have investigated the influence of node mobility on the performance of MANET protocols and have shown the usefulness of our method and the MobiREAL simulator.
