Energy-harvesting and wireless power transfer are quickly becoming game-changing technologies for wireless systems by opening the exciting possibility to build self-sustainable, maintenance-free networks of perpetually communicating devices. In a harvesting wireless device, energy is a random and dynamic quantity that is continuously generated and consumed, and this leads to a fundamental shift in communication system design principles. The broad goal of this project is to lay the theoretical foundations for communication system design under such random energy dynamics. This foundation can enable optimal trade-offs between cost, size, energy and performance in the design of these wireless devices and is critical to scale them to trillions to enable the true emergence of Internet of Everything. The project also promotes the training of research engineers through a plan that envisions close interaction with system and device groups at the home institution.The project consists of three parts. The first part focuses on a point-to-point channel where the transmission energy is provided by an external random energy arrival process. The project develops a framework for approximating the capacity of this channel with explicit guarantees on the approximation gap. The second part looks at remotely powered communication, where the external energy arrival process at the transmitter can be partially controlled by a remote energy source. It develops an information-theoretic formulation for this problem that reveals a novel interactive coding problem, where actions of the remote source depend on previous actions of the transmitter and vice versa. The third part clarifies how wireless devices powered by these new mechanisms can be made to coexist and cooperate forming large scalable wireless networks.

能源收获和无线功率传输迅速成为无线系统改变游戏规则的技术，通过开放令人兴奋的可能性，以建立可永久通信设备的自我维护，无维护的网络。在收获无线设备中，能量是一种随机和动态的数量，可连续生成和消耗，这导致通信系统设计原理的根本变化。该项目的广泛目标是在这种随机能量动力学下为通信系统设计奠定理论基础。该基础可以在这些无线设备的设计中实现成本，大小，能源和性能之间的最佳权衡，并且至关重要的是将它们扩展到数万亿，以使一切的真正出现。该项目还通过一项计划促进研究工程师的培训，该计划设想与家庭机构的系统和设备组密切相互作用。该项目由三个部分组成。第一部分重点是点对点通道，其中外部随机能量到达过程提供了传输能量。该项目开发了一个框架，用于在近似间隙上具有明确保证该通道的容量。第二部分着眼于远程通信，其中发射器处的外部能量到达过程可以由远程能源部分控制。它为此问题开发了一种信息理论公式，该公式揭示了一个新颖的交互式编码问题，远程源的动作取决于发射器的先前动作，反之亦然。第三部分阐明了如何制作这些新机制供电的无线设备，以共存和合作形成大型可扩展无线网络。
