We define as Internet of Things (IoT) the massive and ubiquitous deployment of embedded, usually wireless, communication devices, installed into everyday life objects. Estimates of the IoT scale suggest that, in the not-so-distant future, it will consist of tens of billions of devices! The vast deployment scale of IoT devices has the potential to be the cause of a massive e-waste problem looming on the horizon. Yet, if we ask today how the IoT devices and systems should be designed to extend their useful life to multi-decade, and ideally perpetual, operation, we cannot point to a comprehensive answer. The proposed research program addresses the question of what can be done today at the algorithmic, protocol, and systems level, towards making IoT sustainable. The proposal outlines a systematic approach, with tools and methodologies, to build this long-lasting IoT. The systematic approach described consists of four main components: (a) adding failure resilience for various applications during the design stage, as well as, developing generic means to handle failures during operation, (b) enabling the devices to identify when communication is impaired by interference and endow them with mechanisms to handle broad classes of interference, including as-of-yet-unknown forms, (c) aligning the communication protocol with the application logic, using specialized scheduling, to reduce the energy consumption required to meet the application communication requirements, and (d) harvesting energy from the immediate device environment to attain self-powered operation and autonomy. In the proposed research program, I describe a number of technical approaches to these four directions and plans to empirically validate our methods and tools in the context of our ongoing projects in designing, installing, and programming sensor systems for smart assisted living environments and energy efficient buildings.

我们将物联网（IoT）定义为安装到日常生活对象中的嵌入式（通常是无线）通信设备的大规模和无处不在的部署。对物联网规模的估计表明，在不久的将来，它将由数百亿台设备组成！物联网设备的巨大部署规模有可能成为即将出现的大规模电子垃圾问题的原因。然而，如果我们今天问物联网设备和系统应该如何设计以将其使用寿命延长到数十年，理想情况下是永久运行，我们无法找到一个全面的答案。 拟议的研究计划解决了今天在算法，协议和系统层面可以做些什么的问题，以使物联网可持续发展。该提案概述了一种系统的方法，包括工具和方法，以建立这种持久的物联网。所述的系统方法包括四个主要组成部分：（a）在设计阶段为各种应用增加故障恢复能力，以及开发在操作期间处理故障的通用手段，（B）使设备能够识别通信何时受到干扰的损害，并赋予它们处理广泛类别的干扰的机制，包括未知形式，（c）使用专门的调度将通信协议与应用逻辑对准，以减少满足应用通信要求所需的能量消耗，以及（d）从直接设备环境收集能量以获得自供电操作和自主性。 在拟议的研究计划中，我描述了这四个方向的一些技术方法，并计划在我们正在进行的智能辅助生活环境和节能建筑传感器系统设计，安装和编程项目的背景下，以经验验证我们的方法和工具。
