The transformation of time series into complex networks through visibility graphs is an innovative way to study time-based events. In this work, we use visibility graphs to transform IOTA and IoTeX price volatility time series into complex networks. Our aim is twofold: first, to better understand the markets of the two most capitalised Internet of Things (IoT) platforms at the time of writing. IOTA runs on a public directed acyclic graph (DAG) and IoTeX on a blockchain. Second, to suggest how 5G can improve information security in these two key IoT platforms. The analysis of the networks created by the natural and horizontal visibility graphs shows, first, that both IOTA and IoTeX are still at their infancy in their development, with IoTex seemingly developing faster. Second, both IoT tokens form communities in a hierarchical structure, and third, 5G can accelerate their development. We use intentional risk management as a lever to understand the impact of 5G on IOTA and IoTeX. Our results lead us to provide a set of design recommendations that contribute to improving information security in future 5G-based IoT implementations.

IOTA 和 IoTeX 价格系列的可见性图分析：基于风险的有意将 5G 用于物联网的策略

通过可见性图将时间序列转换为复杂网络是研究基于时间的事件的创新方法。在这项工作中，我们使用可见性图将 IOTA 和 IoTeX 价格波动时间序列转换为复杂网络。我们的目标有两个：首先，在撰写本文时更好地了解两个资本最雄厚的物联网 (IoT) 平台的市场。IOTA 在公共有向无环图 (DAG) 和区块链上的 IoTeX 上运行。其次，建议 5G 如何提高这两个关键物联网平台的信息安全。对自然可见性和水平可见性图创建的网络的分析表明，首先，IOTA 和 IoTeX 仍处于发展初期，IoTex 似乎发展得更快。其次，两个物联网代币都以分层结构形成社区，第三，5G可以加速他们的发展。我们使用故意风险管理作为杠杆来了解 5G 对 IOTA 和 IoTeX 的影响。我们的结果引导我们提供一组设计建议，有助于在未来基于 5G 的物联网实施中提高信息安全性。
