中文摘要： 无线传感器网络应用前景广阔，是近年来的研究热点。虽然它备受关注，却由于能耗成本过高一直难以普及。无线充电技术的出现有望突破这个难关。本项目研究应用无线充电技术对无线传感器网络充电，以解决它不方便充电和更换电池的难题。最近几年对于无线可充电传感器网络的研究都假设网络中所有节点都可以充电，忽视了只有部分节点可以充电的网络。然而部分可充电网络不仅会因为地形限制的原因客观存在，也可以是考虑性价比的人为布置的结果，因此十分重要。本项目首次研究这种部分可充电的网络，并从网络布置、路由和充电路径规划问题等多个方面深入拓展，为部分可充电的无线传感网络提供完整的系统框架。本项目将为克服无线传感网络的能耗难题以及推广无线充电技术的实际应用提供重要的技术储备和理论依据。

英文摘要： Wireless sensor networks are valuable in various domains and thus received many interests in recent years. However, the sensor networks are not dominating in markets due to energy deficiencies. The emerging wireless charging technique offer us new hopes in solving this problem. This project investigates applying wireless charging techniques into wireless sensor networks, to conquer the energy deficiencies in sensor networks. Recent studies on wireless rechargeable sensor networks assumed that all sensor nodes in the networks are rechargeable. This project is distinguished from all the recent studies: we consider a partially-rechargeable sensor network, wherein both rechargeable nodes and non-rechargeable nodes coexist. Both topographic limitations and man-made deployment can lead to such a situation, and thus this kind of network is quite important. This project focuses on the network deployment, routing, and charging path planning problems of partially-rechargeable sensor networks. It aims to design simple and efficient algorithms to balance and satisfy metrics such as network lifetime, financial budget, and routing stretch. This project can provide solid foundations for solving the energy deficiencies of wireless sensor networks and extending the usage of wireless charging techniques.
