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.

无线网络允许用户在不中断连接的情况下改变位置，从而为用户带来移动性。一方面，这为各种位置感知服务开辟了空间。另一方面，这也引起了用户在不同场景下能够或应该在多大程度上识别其位置的担忧。研究的主要重点是解决无线网络中移动设备位置的正确识别问题。问题有两个方面：在E911服务等应用中准确确定移动设备的位置，以及有效保护位置信息，防止对手意图侵犯移动设备用户的隐私。该项目系统地看待问题的双方，探索跨越无线通信两端的解决方案空间，并提供针对各种应用场景的解决方案。症结在于，通过理解、分析、构建和控制系统中不同实体（包括终端设备、基站和跨应用程序的（潜在）对手）之间的复杂交互，确定预期网络服务所需的最少位置信息。网络层和物理层。控制平面和数据平面都被考虑。该项目的智力优点是为正确的位置识别形成科学基础。
