Nanoscale wireless networks are expected to revolutionize a variety of domains, with significant advances conceivable in in-body healthcare. In healthcare, these nanonetworks will consist of energy-harvesting nanodevices passively flowing through the bloodstream, taking actions at certain locations, and communicating results to more powerful Body Area Network (BAN) nodes. Assuming such a setup and electromagnetic nanocommunication in the Terahertz (THz) frequencies, we propose a network architecture that can support fine-grained localization of the energy-harvesting in-body nanonodes, as well as their two-way communication with the outside world. The main novelties of our proposal lie in the introduction of location-aware and Wake-up Radio (WuR)-based wireless nanocommunication paradigms, as well as Software-Defined Metamaterials (SDMs), to THz-operating energy-harvesting in-body nanonetworks. We argue that, on a high level, the proposed architecture can handle (and actually benefits from) a large number of nanonodes, while simultaneously dealing with a short range of THz in-body propagation and highly constrained nanonodes.

借助能量收集实现位置感知的体内太赫兹纳米网络

纳米级无线网络有望在各种领域带来革命性的变化，并且在体内医疗保健领域有望取得重大进步。在医疗保健领域，这些纳米网络将由能量收集纳米设备组成，这些设备被动地流过血流，在某些位置采取行动，并将结果传达给功能更强大的人体局域网（BAN）节点。假设以太赫兹（THz）频率进行这种设置和电磁纳米通信，我们提出了一种网络体系结构，该体系结构可支持能量收集体内纳米节点的细粒度定位以及它们与外界的双向通信。我们提案的主要新颖之处在于引入了基于位置感知和唤醒无线电（WuR）的无线纳米通信范例，以及软件定义的超材料（SDM），到太赫兹能量收集体内纳米网络。我们认为，在较高的层次上，提出的体系结构可以处理（并实际上受益于）大量的纳米节点，同时可以处理THz体内短距离传播和高度受限的纳米节点。
