中文摘要： 无线传感器网络在战场侦察和环境监测等众多领域有着广泛的应用前景。传统的传感器网络由于sink节点缺乏移动和长时间暴露，易遭到恶意节点攻击，导致整个网络系统服务质量下降甚至瘫痪。移动无人机的出现大大改善了系统性能和提高了系统可靠性，在移动环境下如何确保整个系统的安全实现显得尤为重要。本项目充分考虑系统主客体在时间、空间和社会关系的多维度因素，以无人机行为模型为中心，以最小化时间空间复杂度和确保系统安全为目标，提出一整套适合于无人机传感器网络的安全解决方案：我们将提出适用于精准描述移动无人机行为的多维关联模型；基于无人机行为，在实际场景约束条件下研究为保证通信交互双方链路安全的密钥分发策略、保证数据安全的缓存技术和保证服务安全的节点合作机制；基于无人机行为，在系统性能分析基础上，研究通过节点调度和资源调配提升网络系统服务质量的优化方法。根据上述研究成果，开发无人机传感器网络的动态原型系统。

英文摘要： Wireless sensor networks (WSNs) have been intensively applied in various domains, such as battlefield surveillance, environment monitoring, etc. The sink node in traditional WSNs are static and exposed for a long time. Consequently, such nodes are prone to be attacked and thus the quality of service (QoS) will be decreased even disabled. Mobile unmanned aerial vehicles (UAVs) can be used to ameliorate the network performance mentioned above and enhance the system reliability. However, the secure issues that are not studied completely should be reconsidered in such mobile scenario. In this proposal, integrated with UAV, we present the security solutions in WSNs while minimizing the design complexity. First of all, the multi-dimensional factors including time, space, social relationship are considered to model the UAV behavior accurately. Secondly, motivated by the node behavior we have described, the strategy of key predistribution for (communication) link security, the technique of transportation for data security, and the scheme of node cooperation for service security, are all proposed. Thirdly, motivated by the node behavior, the network performance is analyzed. In addition, the optimization of network performance via node scheduling and resource allocation is also provided. In the end, based on the aforement
