可充电协作中继网络作为一种新兴的通过获取环境能源(如太阳能)、无线射频能量为节点充电的无线网络，克服了有限的电池电量对网络操作的限制。然而，选择何种能源为节点充电以及此时中继节点采用何种中继策略转发源节点的数据、如何基于节点的能量补充过程有效地分配网络资源仍是亟待解决的问题。为此，本项目拟融合现有的基于环境能源、基于无线射频的能量补充策略、以及能量和无线信息同步传递技术，构建协作中继网络新的充电-中继策略，并进行策略性能分析，从而解决网络的能量补充及信息中继问题；基于所提充电-中继策略并考虑节点能量补充量事先未知的特性，构建典型可充电协作中继网络的吞吐量最大化模型，并通过最优化理论、博弈论等给出实时的资源分配算法及有限时间内的离线算法，从而解决网络的功率分配及中继选择问题。同时，基于最优化和稳定性理论研究所提出算法的收敛性和网络的稳定性，且通过数值仿真分析所提充电-中继策略及算法的有效性。

Rechargeable cooperative relay networks, as a type of emerging wireless networks in which network nodes can harvest energy from ambient sources such as solar or radio-frequency (RF) signals, can alleviate effectively the restriction on network operations due to limited battery energy. However, which kind of energy to be chosen for charging network nodes, what kind of relaying protocols relay nodes should choose for forwarding the source information, and how to efficiently allocate network resources based on the energy replenishment process remain key problems to be addressed urgently. To solve these problems, by integrating the existing energy replenishment strategies, and simultaneous wireless information and energy transfer technology, we will first propose several new harvesting-relaying protocols and analyze the performance so as to address the energy replenishment and relaying problem for rechargeable cooperative relay networks; then on the basis of these harvesting-relaying protocols, we will establish several models for network throughput maximization by considering the energy replenishment profile which is unknown in advance, and propose the corresponding online and offline resource allocation algorithms over a finite number of transmission intervals in order to solve the joint relay selection and power allocation problem for rechargeable cooperative relay networks. Furthermore, we will study the convergence of these algorithms and the stability of networks on the basis of optimization theory and stability theory, and analyze the validity of the proposed harvesting-relaying protocols and resource allocation algorithms.
