Collaborative Research: WN: Proper Location Identification in Wireless Networks

无线网络允许用户在不中断连接的情况下更改位置，从而为用户带来移动性。一方面，这为各种各样的位置感知服务打开了空间。另一方面，它也引起了用户的关注，即在不同的场景下可以或应该在多大程度上识别他们的位置。研究的主要焦点是解决无线网络中移动设备位置的正确识别。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免受意图侵犯移动设备用户隐私的攻击者的攻击。该项目系统地看待问题的两端，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。问题的症结在于通过了解、分析、组织和控制系统中不同实体(包括终端设备、基站和跨越应用、网络和物理层的(潜在)对手)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。该方案同时考虑了控制面和数据面，其智能化的优点是为正确的位置识别提供了科学依据。

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.
