摘要

这项工作评估了在太赫兹（THz）频段的紧凑型自组织网络的性能。该网络由几个能量收集物联网（IoT）辅助用户（su）围绕一个中继节点（RN），以及随机定位的主用户（pu）组成。RN连接到一个接入点（AP）， AP又直接连接到互联网云。我们假设每个通信节点都配备有定向天线。在认知基础范式下运行，小区域自组织网络允许su从各种pu中收集能量，使其适合小规模商业机构的实际应用。本研究的主要重点是考虑到上述场景，对SU的覆盖概率和平均吞吐量进行分析评估，这在现有文献中是缺失的。通过大量的数值模拟来验证理论结果。

Performance analysis of energy harvesting IoT network in THz communication system with randomly located nodes with directional antenna

This work assesses the performance of a compact ad-hoc network in the terahertz (THz) frequency band. The network comprises of several energy-harvesting internet of things (IoT) secondary users (SUs) surrounding a relay node (RN) amidst randomly positioned primary users (PUs). The RN is connected to an access point (AP), which, in turn, has a direct connection to the internet cloud. We assume that every communication node is equipped with directional antenna. Operating under the cognitive underlay paradigm, the small area ad-hoc network allows SUs to harvest energy from various PUs, making it suitable for practical applications in small-scale commercial establishments. The primary focus of this study is the analytical evaluation of the coverage probability and average throughput of a SU considering the mentioned scenario which is missing in available literature so far. Extensive numerical simulations are conducted to establish the theoretical results.
