论文摘要
感官互联网(IOS)对所有人类“受体”具有完美无瑕的触觉式通信的希望,因此模糊了虚拟和真实环境的差异。我们从iOS授权的引人注目的用例以及关键网络要求开始开始。然后,我们详细介绍了新兴的语义通信和人工智能(AI)/机器学习(ML)范式以及6G技术如何满足iOS用例的要求。一方面,可以应用语义通信来提取有意义的重要信息,因此可以有效利用资源并利用接收器的先验信息以满足iOS要求。另一方面,AI/ML通过利用在iOS边缘节点和设备中生成的大量数据以及通过智能代理优化iOS性能来促进节俭网络资源管理。但是,部署在边缘的智能代理并没有完全意识到彼此的决定和彼此的环境,因此它们是在部分而不是完全可观察到的环境中运行的。因此,我们提出了一项针对改善用户设备(UE)吞吐量和能源消耗的部分可观察到的马尔可夫决策过程(POMDP)的案例研究,因为它们对iOS用例至关重要,使用加固学习来迅速激活和停用载体聚集中的组件载体。最后,我们概述了iOS实施以及采用语义通信,边缘情报以及在iOS环境中的部分可观察性下学习的挑战和开放问题。
The Internet of Senses (IoS) holds the promise of flawless telepresence-style communication for all human `receptors' and therefore blurs the difference of virtual and real environments. We commence by highlighting the compelling use cases empowered by the IoS and also the key network requirements. We then elaborate on how the emerging semantic communications and Artificial Intelligence (AI)/Machine Learning (ML) paradigms along with 6G technologies may satisfy the requirements of IoS use cases. On one hand, semantic communications can be applied for extracting meaningful and significant information and hence efficiently exploit the resources and for harnessing a priori information at the receiver to satisfy IoS requirements. On the other hand, AI/ML facilitates frugal network resource management by making use of the enormous amount of data generated in IoS edge nodes and devices, as well as by optimizing the IoS performance via intelligent agents. However, the intelligent agents deployed at the edge are not completely aware of each others' decisions and the environments of each other, hence they operate in a partially rather than fully observable environment. Therefore, we present a case study of Partially Observable Markov Decision Processes (POMDP) for improving the User Equipment (UE) throughput and energy consumption, as they are imperative for IoS use cases, using Reinforcement Learning for astutely activating and deactivating the component carriers in carrier aggregation. Finally, we outline the challenges and open issues of IoS implementations and employing semantic communications, edge intelligence as well as learning under partial observability in the IoS context.
