Abstract

Intra-body flow-guided nanonetworks are nanonetworks that aim to deploy the Internet of Nanothings (IoNT) into the human cardiovascular system. In these nanonetworks, nano-nodes flow in blood vessels (including arteries and veins) for detecting sensitive biological/physical data. Nano-nodes dispatch data to each other and outside devices via Terahertz (THz) waves. Monitoring of different biomarkers, detection of infectious agents, localization of cancer cells, accurate drug delivery, and other medical applications are all potential applications utilizing such networks. However, the physical limitations of the nano-nodes and the high attenuation of terahertz waves in the blood limit data transmission. Therefore, based on the characteristic of laminar blood flow in blood vessels, we proposed a central high-speed lane routing protocol in Yao et al. (2023), which utilized high-speed nano-nodes in the central layer of the blood flow to form a directional relay chain for other non-centric nano-nodes. In this paper, the proposed protocol is studied in depth, described in detail, and evaluated in the parameters of the hand vein scenario. The proposed protocol works well in new scenarios and proves its efficiency in intra-body communication.

CHLR：太赫兹波段通信中体内流引导纳米网络的中央高速车道路由协议

体内流动引导纳米网络是一种旨在将纳米物联网（IoNT）部署到人体心血管系统中的纳米网络。在这些纳米网络中，纳米节点在血管（包括动脉和静脉）中流动，以检测敏感的生物/物理数据。纳米节点通过太赫兹（THz）波相互传送数据，并传送到外部设备。监测不同的生物标志物、检测传染性病原体、定位癌细胞、精确给药以及其他医疗应用都是利用此类网络的潜在应用。然而，纳米节点的物理限制和血液中太赫兹波的高衰减限制了数据传输。因此，根据血管中层流血流的特点，我们在 Yao 等人（2023）中提出了一种中心高速车道路由协议，利用血流中心层的高速纳米节点为其他非中心纳米节点形成定向中继链。本文对提出的协议进行了深入研究、详细描述，并根据手部静脉场景参数进行了评估。提出的协议在新的场景中运行良好，证明了其在体内通信中的效率。
