Split Learning in 6G Edge Networks
With the proliferation of distributed edge computing resources, the 6G mobile
network will evolve into a network for connected intelligence. Along this line,
the proposal to incorporate federated learning into the mobile edge has gained
considerable interest in recent years. However, the deployment of federated
learning faces substantial challenges as massive resource-limited IoT devices
can hardly support on-device model training. This leads to the emergence of
split learning (SL) which enables servers to handle the major training workload
while still enhancing data privacy. In this article, we offer a brief overview
of key advancements in SL and articulate its seamless integration with wireless
edge networks. We begin by illustrating the tailored 6G architecture to support
edge SL. Then, we examine the critical design issues for edge SL, including
innovative resource-efficient learning frameworks and resource management
strategies under a single edge server. Additionally, we expand the scope to
multi-edge scenarios, exploring multi-edge collaboration and mobility
management from a networking perspective. Finally, we discuss open problems for
edge SL, including convergence analysis, asynchronous SL and U-shaped SL.Comment: 7 pages, 6 figure

IETF standardization in the field of the Internet of Things (IoT): a survey
Smart embedded objects will become an important part of what is called the Internet of Things. However, the integration of embedded devices into the Internet introduces several challenges, since many of the existing Internet technologies and protocols were not designed for this class of devices. In the past few years, there have been many efforts to enable the extension of Internet technologies to constrained devices. Initially, this resulted in proprietary protocols and architectures. Later, the integration of constrained devices into the Internet was embraced by IETF, moving towards standardized IP-based protocols. In this paper, we will briefly review the history of integrating constrained devices into the Internet, followed by an extensive overview of IETF standardization work in the 6LoWPAN, ROLL and CoRE working groups. This is complemented with a broad overview of related research results that illustrate how this work can be extended or used to tackle other problems and with a discussion on open issues and challenges. As such the aim of this paper is twofold: apart from giving readers solid insights in IETF standardization work on the Internet of Things, it also aims to encourage readers to further explore the world of Internet-connected objects, pointing to future research opportunities
Towards Confident Body Sensor Networking
With the recent technology advances of wireless communication and lightweight low-power sensors, Body Sensor Network (BSN) is made possible. More and more researchers are interested in developing numerous novel BSN applications, such as remote health/fitness monitoring, military and sport training, interactive gaming, personal information sharing, and secure authentication. Despite the unstable wireless communication, various confidence requirements are placed on the BSN networking service. This thesis aims to provide Quality of Service (QoS) solutions for BSN communication, in order to achieve the required confidence goals.;We develop communication quality solutions to satisfy confidence requirements from both the communication and application levels, in single and multiple BSNs. First, we build communication QoS, targeting at providing service quality guarantees in terms of throughput and time delay on the communication level. More specifically, considering the heterogeneous BSN platform in a real deployment, we develop a radio-agnostic solution for wireless resource scheduling in the BSN. Second, we provide a QoS solution for both inter- and intra-BSN communications when more than one BSNs are involved. Third, we define application fidelity for two neurometric applications as examples, and bridge a connection between the communication QoS and application QoS
Sounding the Future: Digital Radio and CD-Quality Audio
Central to the early effort to win acceptance for DAB in the early 1990s was an extensive process of promotion of the many claimed advantages of the new broadcasting technology. Digital radio broadcasting under the Eureka 147 DAB project offered many technical enhancements – more efficient use of the spectrum, improved transmission methods, and lower running costs – features that were attractive to industry professionals, broadcasting organisations, regulators and spectrum planners. But digital radio was also designed as a consumer proposition offering audiences a new and improved listening experience with ease of tuning, reliable reception, text and data services, interactive features, and significantly, ‘CD-quality’ audio. The promise of digital radio was to be ‘the sound of future’
