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.

0627147 NeTS-NBD：多跳无线网络：移动性改变匿名摘要由于节点移动性和新的匿名性问题，如运动跟踪，多跳无线网络中的匿名通信系统面临着巨大的挑战。此外，匿名性还受到正在使用的无线窃听技术、加密方法、用户流量模式、运动模式和路由协议的影响。这些因素的结合需要进行深入调查，以了解它们对匿名保护程度的影响，并创建可用作业绩评估基线的综合衡量标准。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。具体地说，这个项目制定了正式的定义，并对匿名问题和新出现的匿名问题进行分析。该项目还开发了新的度量标准来量化新的匿名属性，并使用它们通过深入模拟来开发关于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，制定关于路由策略的最佳实践。这一努力将影响对移动多跳无线网络中匿名性问题的基本理解，并为研究生培训提供一个极好的平台。
