NetSE: Medium: Energy Harvesting Active Networked Tags (EnHANTs)

这项研究将设计和实现能量收集有源网络标签（EnHANTs）：可以连接到传统上不联网的任意对象的小型设备，如书籍，家具，墙壁，门，玩具，钥匙，农产品和衣服。 EnHANTs收集能量，以延迟容忍的方式联网，并调整其通信和联网机制以满足其现有的能源限制。 标签将是薄的，机械灵活，小-几平方厘米最多。 EnHANTs是一种颠覆性和变革性的技术，能够实现传统技术无法实现的新型对象跟踪应用，例如丢失物品恢复、灾难恢复、紧急警报和时空邻近信息。EnHANTs需要超级节能的架构和设计，以便仅使用通过收集积累的能量来有效地运行。这种严格的能源限制带来了远低于蓝牙和Zigbee等传统标准的超低功耗要求。 满足这些要求使EnHANTs能够在能源限制明显更高的环境中保持功能。 考虑到严重的能源限制，需要重新思考如何进行能源收集和存储，通信和联网。 PI采用全面的跨层设计方法，结合了网络、通信、低功耗电子和有机能量收集设备方面的专业知识，使效率提高了几个数量级，使EnHANTs成为可能。 将部署和测试一个网络标签测试平台，展示使用定制硬件开发的能量收集、通信和网络组件。该研究将导致基于低功耗能量收集标签的新应用和服务，社会可以从中受益。

This research will design and implement energy-harvesting active networked tags (EnHANTs): small devices that can be attached to arbitrary objects that are traditionally not networked, such as books, furniture, walls, doors, toys, keys, produce, and clothing. EnHANTs harvest energy, network in a delay-tolerant fashion, and adapt their communications and networking mechanisms to satisfy their existing energy constraints. The tags will be thin, mechanically flexible, and small - a few square cm at most. EnHANTs are a disruptive and transformational technology that enables novel object tracking applications which are unavailable with conventional technologies, such as lost item recovery, disaster recovery, emergency alerts, and spatio-temporal proximity information.EnHANTs require a super-energy efficient architecture and design to operate effectively using only energy accumulated via harvesting. Such severe energy restrictions impose ultra-low power requirements that are much lower than traditional standards such as Bluetooth and Zigbee. Meeting these requirements gives EnHANTs the capability to remain functional in environments that are significantly more energy constrained. Given the severe energy constraints, a total rethinking of how to perform the energy harvesting and storage, communications, and networking is needed. The PIs take a comprehensive cross-layer design approach that combines expertise in networking, communications, low-power electronics, and organic energy-harvesting devices to make the efficiency improvements of several orders of magnitude that make EnHANTs possible. A test platform of networked tags will be deployed and tested demonstrating the energy harvesting, communication, and networking components developed using custom hardware.The research leads to new applications and services based on the low power, energy harvesting tags, that society can benefit from in a significant way.
