无源传输网络理论与关键技术

The key tasks of Internet of Things(IoT) are Ubiquitous sensing, wireless data communicating and data processing. In spite of rapidly developed and widely used more than one decade, the promise of large scale pervasive applications is still hindered by the limitation of power supply to sensing/networking/computing devices. .Having the IoT applications as backgrounds, we will intensively studying the foundation theories and key techniques in battery free communication networks. In the network, the node will be battery-free, with the ability of charging from ambient energy. Different from the traditional wireless networks, the battery free communication network is energy-centric. Moreover, such network has very weak connection, also the harvested ambient energy is fluctuating, unbalanced, and unreliable. It brings great challenges for sensing, transmitting and computing in network. In this project, the following tasks will be deeply investigated, which includes: 1)Research on the energy harvesting theories and methodologies; 2)Study of the network construction and communication techniques and theories for energy-centric networks; 3)Development of the high quality sensory data acquisition methods and theories for energy-centric networks;4)Research of the distributed in-network computation algorithms and theories for energy-centric networks. A series of the complete theories and techniques will be proposed by this project, and the success of the project will potentially make contribution to the development and pervasive utilization of IoT for our country.

物联网的核心任务是无处不在的数据感知、以无线为主的数据传输以及智能化的数据处理。虽然近几年物联网技术和应用发展迅猛，但节点供能障碍极大限制了物联网的大规模普适应用。为此，本项目以物联网为背景，以感知数据的获取、无线传输、分布式计算为核心，深入研究无源传输网的基础理论与关键技术。在无源传输网络中，节点可以是无源的（battery free），具有从环境中获取能量的能力。无源传输网络具有节点能量的“震荡性、失衡性、受限性”，以及网络连接脆弱性等特点，为无源传输网络的感知数据获取、传输与计算带来的大量挑战问题。针对这些挑战问题，我们拟研究如下关键科学技术问题：能量获取的理论与方法；以能量为中心的组网与通信的理论与技术；高质量感知数据获取的理论和方法；以能量为中心的分布式数据计算理论和算法。提出一系列完整的理论与技术，为我国物联网进一步普适应用与发展做出贡献。
