6G offers superior reliability,
speed, latency and ubiquity. However, resource allocation is a priority thanks to the scarcity of spectrum, while security is an essential feature. Blockchain could establish secure communication in 6G networks as well as managing the resource allocation and sharing process.
In this paper, we focus on the multi-traffic scheduling in VNF-based service orchestration. We propose a dynamic multi-service Quality of Service (QoS) Guarantee approach, which aims to reduce data coupling between multiple services and bandwidth preemption. Then we devise a service scheduling algorithm to allocate link resources for network services. The simulation results demonstrate that our method efficiently reduces network congestion and ensures high-priority services’ trouble-free running.
Energy consumption is an important point which is crucial for green communications in 6G era, especially for those networks with limited life span or affected by dangerous environments where batteries are inconvenient to be changed. Therefore, energy harvesting (EH) has become a very attractive research field in recent years. In this paper, a new type of two-way EH relay beamforming system with two transceivers and many single-antenna relays is designed.
The great achievements in electronics, automation, and digital communication technologies in the sixth-generation (6G) era has significantly accelerated the development of smart wearables and the personal ecosystems realizing the Internet of wearable things (IoWT). As the IoWT technologies have not matured yet, a keen knowledge of current states and future research trends is of importance to promote the popularization of the technology. In this review article, we investigate state-of-the-art characteristics of IoWT to identify its advancements and benefits from 6G technologies.
This paper aims at revealing the main technical issues that have not been fully addressed by the existing LEO-SAN designs, from three aspects namely random access, beam management and Doppler-resistant transmission technologies. Promising technologies to address these challenges are also discussed, respectively. Finally, the future research directions are envisioned.
Heterogeneity among distributed edge devices and the limitation of resources may degrade the training efficiency of Federated Edge Learning over 6G-enabled mobile edge computing (MEC) networks. Taking this challenge into account, a novel federated learning scheme is proposed in this paper to accelerate the training process.
6G communication networks must be highly dependable. We take four dependability concepts such as reliability, availability, safety and security, and discuss the dependability of 6G networks. This
article, in summary, provides interesting insights into existing
challenges and advocates future research through highlighting
the most important research directions to make 6G dependable.
This Next G Alliance (NGA) report provides expert recommendations about which technologies will be key to 6G and where further research is needed. Technology without a purpose is just a novelty. In order to understand how 6G will be used, views were gathered from experts in the areas of:
– Applications and Requirements
