NeTS-NBD: Measurement-Based Mobility Modeling for MANETs

移动自组织网络（manet）具有内在的协作性。由于在manet中可能所有通信设备都经历不同程度的移动性，因此它们严重依赖附近的节点来维持网络连接。因此，移动节点的底层移动模式强烈影响MANET协议的性能。对真实场景中产生的移动模式进行建模和再现对于基于仿真的MANET协议性能研究非常重要。本研究的主要目标是移动性建模和生成。与现有工作相比，本研究侧重于从真实场景中建模移动模式，并在可用于创建逼真仿真环境的合成移动轨迹中模拟这些模式。所提出的模型具有理想的特征，即可定制以匹配任何真实场景（例如，城市中的公交车，校园中的学生或牛群中的斑马），同时允许方便的多样化（即，允许更改节点的数量，密度等）。这个项目的主要交付物是一套移动模型和使用它们生成轨迹的工具。由于在可预见的未来，MANET性能评估将基于网络仿真，因此预计本项目的结果将广泛应用于MANET社区。设想所提出的模型将有效地取代随机路径点作为任何MANET性能评估中使用的标准移动性模型。

NeTS-NBD: Measurement-Based Mobility Modeling for MANETsAward 0626850Mihail SichitiuMobile ad hoc networks (MANETs) are inherently cooperative. Because possibly all communicating devices may undergo varying degrees of mobility in MANETs, they rely heavily on nearby nodes to maintain network connectivity. Therefore, the underlying mobility patterns of mobile nodes strongly influence the performance of MANET protocols. Modeling and reproducing the mobility patterns arising from real scenarios are very important for simulation-based performance studies of MANET protocols.The primary goal of the study is mobility modeling and generation. In contrast to existing work, this research focuses on modeling the mobility patterns from real scenarios and emulating such patterns in synthetic mobility traces that can be used for creating realistic simulation environments. The proposed model has the desirable characteristics that it is customizable to match any real scenario (e.g., busses in a city, students in a campus, or zebras in a herd), while allowing for convenient diversification (i.e., allows changing the number of nodes, density, etc.).The main deliverables of this project are a suite of mobility models and the tool that uses them to generate the traces. Since for the foreseeable future MANET performance evaluation will be based on network simulations, it is expected that the results of this project will be widely used in the MANET community. It is envisioned that the proposed model will effectively replace the random way point as the standard mobility model used in any MANET performance evaluation.
