The context of the research and applications:Technological advances and changes in the social perception of technology are fueling interest in small, flexible, wearable and implantable devices for the Internet of Things (IoT). The IoT describes the network of physical objects (things) embedded with sensors, hardware and software, and other technologies to connect and exchange data with other devices over the Internet. These aim a range of application domains, including agriculture, home and building automation, radio-frequency identification (RFID), and assisted living and health care. For reasons of installation location, ease, or aesthetics, many of the networked devices which underpin these applications do not have access to a wired electricity source; instead, they rely on batteries as their primary power source. However, battery-powered devices inevitably experience a direct tension between market demands requiring long lifetimes and small physical dimensions and weight. As a result, research has looked towards replacing batteries with energy harvesting from alternative sources. However, although energy harvesting provides infinite energy in theory, its output varies and frequently fails and is overall unreliable. Its aims and objectives:To address this challenge, the proposed research project aims to design a new class of sensor systems for IoT applications that are resilient to intermittency and adjust to the varying and unreliable supply such as harvested energy. To achieve this, the project will first target the design and validation of methods to preserve the system state, or, in other words, to enable quick saving of the system state before a power failure occurs and restoring it once the supply recovers. Secondly, the project will concentrate on using the energy efficiently when available, which means designing and validating strategies for runtime power management to perform reliably and maximise performance and prolonge operations under varying supply conditions. Finally, the project will focus on communication and networking for sporadic exchange between sensor devices intermittently (or transiently) powered. The problem is that sensor devices cannot receive and forward data if the power supply is unavailable. Therefore, this project will focus on designing transceivers and protocols for an efficient broadcast mechanism under varying supply conditions (energy-aware networks).

研究和应用背景：技术进步和社会对技术认知的变化正在激发人们对小型、灵活、可穿戴和植入式物联网 (IoT) 设备的兴趣。物联网描述了嵌入传感器、硬件和软件以及其他技术的物理对象（事物）网络，用于通过互联网与其他设备连接和交换数据。这些产品针对一系列应用领域，包括农业、家庭和楼宇自动化、射频识别 (RFID) 以及辅助生活和医疗保健。出于安装位置、便利性或美观的原因，支持这些应用的许多联网设备无法使用有线电源；相反，他们依靠电池作为主要电源。然而，电池供电的设备不可避免地会遇到要求长寿命和小物理尺寸和重量的市场需求之间的直接矛盾。因此，研究着眼于用替代来源的能量收集来取代电池。然而，虽然能量收集理论上可以提供无限的能量，但其输出变化很大，并且经常出现故障，总体上不可靠。其目的和目标：为了应对这一挑战，拟议的研究项目旨在为物联网应用设计一种新型传感器系统，该系统能够适应间歇性并适应不断变化和不可靠的供应，例如所收集的能量。为了实现这一目标，该项目首先将目标是设计和验证保存系统状态的方法，或者换句话说，能够在发生电源故障之前快速保存系统状态，并在电源恢复后恢复系统状态。其次，该项目将专注于有效利用可用能源，这意味着设计和验证运行时电源管理策略，以便在不同的供电条件下可靠地执行并最大限度地提高性能并延长运行时间。最后，该项目将重点关注间歇性（或瞬时）供电的传感器设备之间的零星交换的通信和网络。问题是，如果电源不可用，传感器设备将无法接收和转发数据。因此，该项目将重点设计收发器和协议，以在不同的供电条件（能源感知网络）下实现高效的广播机制。
