Collaborative Research: WN: Proper Location Identification in Wireless Networks

无线网络通过允许用户在不中断连接的情况下改变位置来为用户带来移动性。一方面，这为各种位置感知服务开辟了空间。另一方面，它也引起了用户的关注，在什么程度上他们的位置可以，或应该，在不同的scenaries.The研究的主要焦点是解决在无线网络中的移动终端位置的正确识别。这个问题有两个方面：一是在诸如E911服务的应用中准确确定移动终端的位置，二是有效保护位置信息不受意图侵犯移动终端用户隐私的攻击者的攻击。该项目系统地看待问题的两个方面，探索跨越无线通信两端的解决方案空间，并为各种应用场景提供解决方案。关键点是通过理解、分析、结构化和控制系统中不同实体之间的复杂交互来确定预期网络服务所需的最小位置信息，这些实体包括终端设备、基站和（潜在）对手，跨越应用、网络和物理层。该方案既考虑了控制平面，又考虑了数据平面，其智力价值在于为正确的位置识别提供了科学的基础。

Wireless networks bring mobility to users by allowing them to change location without disrupting connectivity. On one hand, this opens space for a wide variety of location-aware services. On the other hand, it also poses a concern to users as to what extent their location can, or should, be identified in different scenarios.The main focus of the research is to address the proper identification of mobile device locations in wireless networks. There are two sides of the problem: the accurate determination of a mobile device's location in applications such as E911 services, and the effective protection of location information against adversaries which intend to intrude mobile device users' privacy. This project takes a systematic view of both sides of the problem, explores a solution space that spans both ends of wireless communication, and delivers solutions for various application scenarios. The sticking point is to determine the minimum location information necessary for the intended network service by understanding, analyzing, structuring, and controlling the complex interactions among different entities in the system including end-devices, base stations, and (potential) adversaries across application, network, and physical layers. Both control plane and data plane are considered.The intellectual merit of this project is to form a scientific foundation for proper location identification.
