中文摘要: 本课题针对无线传感器网络中重要节点位置隐私保护存在的若干挑战性问题,提出一系列解决方案,实现对单类以及多类重要节点位置的有效保护:首先,针对已有静态源位置隐私保护协议不适用于源节点可持续移动这一问题,提出一种移动源位置隐私保护协议;其次,针对已有基站位置隐私保护研究未兼顾从拓扑发现到数据传输整个过程这一问题,提出一种面向全过程的基站位置隐私保护方案。最后,针对源或基站的位置隐私保护割裂进行研究无法同时保护源和基站位置这一问题,提出一种基于主动检测的节点位置隐私保护方案,以增加检测节点部署开销为代价,实现在同一时空环境中对源和基站位置的保护,且进一步优化源或基站位置隐私保护策略。

英文摘要: This proposal is oriented to several challenge issues concerning location privacy protection of important nodes in wireless sensor networks. We propose a suit of schemes for protecting location privacy of different types of nodes both individually and comprehensively. First, in the view of existing location privacy protection protocols are all designed for stationary sources, a mobile source-oriented protocol is proposed to protect mobile sources; second, since existing location privacy protection protocols cannot provide comprehensive base-station protection, we propose a novel location privacy protection scheme which can protect base-station location from topology discovery phase straight to data transmission phase; finally, in order to protect the locations of source and base-station at the same time, we propose a node location protection scheme based on active detection strategies. The scheme can enhance the protection of source and base-station location both individually and simoutaneously at the cost of extra deployment effort for detection nodes.
