NeTS-NBD: Multihop Wireless Networking: Mobility Changes Anonymity

多跳无线网络：移动性的变化匿名摘要由于节点的移动性和新的匿名性问题，如运动轨迹，多跳无线网络中的匿名通信系统受到了极大的挑战。此外，匿名程度还受到无线窃听技术、加密方法、用户流量模式、运动模式和所使用的路由协议的影响。需要对这些因素的组合进行深入调查，以了解它们对匿名保护程度的影响，并创建可作为性能评估基线的综合测量方法。这个项目的重点是获得这样的理解和测量，并通过采取强调运动行为影响的方法来制定对策策略。具体来说，该项目开发了正式的定义，并对匿名问题和新出现的匿名问题进行了分析。该项目还开发了新的指标来量化新的匿名属性，并使用它们通过深入模拟来开发网络性能和可能的权衡的初步结果。这些研究将导致在处理不同的安全假设和隐私级别时，有关路由策略的最佳实践的发展。这项工作将影响对移动多跳无线网络中匿名问题的基本理解，并为研究生培训提供一个很好的平台。

0627147NeTS-NBD: Multihop Wireless Networking: Mobility Changes AnonymityAbstractAnonymous communications systems in multi-hop wireless networks are challenged greatly due to node mobility and new anonymity concerns, such as motion traces. In addition, the degree of anonymity is affected by the wireless eavesdropping techniques, encryption methods, user traffic patterns, motion pattern and routing protocols that are in use. The combination of these factors requires an in-depth investigation in order to understand their influence to the degree of anonymity protection and to create comprehensive measurements that can be used as a baseline for performance evaluation. This project is focused around obtaining such understanding and measurement, and developing countermeasure strategies by taking an approach that emphasizes the impact from motion behaviors. Specifically, this project develops formal definitions and conducts analyses of the anonymity problem and emerging anonymity concerns. The project also develops new metrics to quantify new anonymity properties and uses them to develop preliminary results on network performance and possible trade-offs through in-depth simulations. These studies will lead to the development of best-practices regarding routing strategies when dealing with different security assumptions and levels of privacy. This effort will impact the fundamental understanding of the anonymity issue in mobile multi-hop wireless networking and provide an excellent platform for graduate student training.
