Wireless networks composed of nodes that can harvest energy from the environment represent the green future of communications. Utilizing the harvested ambient energy improves the environmental impact of wireless devices in the global scale, while extending the network lifetime indefinitely and making the devices truly mobile. Energy harvesting (EH) brings new dimensions to system design in the form of randomness and intermittency of available energy, as well as additional system issues such as energy storage capacity and processing complexity. Additionally, the deployment of EH wireless networks calls for novel techniques for resource and interference management, cooperation among EH nodes, as well as cross-layer optimization of the network. The research focuses on a new set of challenges brought about by wireless networks composed of EH nodes. The research directions are divided into four major thrusts. (1) The first challenge is to understand the fundamental limit of EH communications in the information theoretic setting, accounting for random and intermittent supply of available energy, finite battery capacity with storage and withdrawal efficiencies. The special cases for low-power and high-power regimes are of particular interest. (2) In order to make efficient use of the available resources, joint energy scheduling and spectral and/or spatial resource allocation in EH networks exploiting the inherent structure of the resource allocation problems becomes an important problem. (3) Different EH nodes in the network can share their harvested energy either through the presence of power line between them, or through wireless charging. The research studies previous thrusts with energy and data cooperation. (4) The research investigates efficient distributed cross-layer solutions to maximize the total system utility subject to data and energy queuing stability constraints.

由可以从环境中收集能量的节点组成的无线网络代表了通信的绿色未来。利用收获的环境能量可以改善无线设备在全球范围内的环境影响，同时无限期地扩展网络寿命并使设备真正移动。能源收集（EH）以随机性和可用能量间歇性的形式为系统设计带来了新的维度，以及其他系统问题，例如储能能力和处理复杂性。此外，EH无线网络的部署还需要用于资源和干扰管理，EH节点之间的合作以及网络的跨层优化的新技术。该研究的重点是由EH节点组成的无线网络带来的新挑战。研究方向分为四个主要推力。 （1）第一个挑战是了解信息理论环境中EH通信的基本限制，考虑到可用的能源的随机和间歇性供应，有限的电池容量，储存和提款效率。低功率和高功率制度的特殊案例特别感兴趣。 （2）为了有效利用可用资源，在EH网络中利用资源分配问题固有结构的EH网络中的联合能源调度和/或空间资源分配成为一个重要问题。 （3）网络中的不同EH节点可以通过它们之间的电源线或通过无线充电来共享其收获的能量。研究以前的研究通过能量和数据合作推动。 （4）研究研究了有效的分布式跨层解决方案，以最大程度地利用数据和能量排队稳定性约束的总系统实用性。
