Pages: 8 - 15 Abstract: Recent advances in vehicular technologies illuminate the significance of vehicular networking, where information dissemination between constituent network elements plays a crucial role. Information sharing in vehicular networks is challenging because mobility introduces a dynamic environment with overwhelming data traffic. Information-Centric Networking (ICN) reduces overheads by in-network caching and name-oriented communication to mitigate these challenges. However, network resources can be used more efficiently if both RSUs and vehicles are managed autonomously. This article proposes autonomous networking to improve information dissemination in vehicular ICN by using available in-network contextual information. First, a Segment-aware ICN (SA-ICN) scheme is proposed by developing a new dynamic namespace convention. Then, we extend SA-ICN by proposing a Segment and Provider-aware Gossiping enabled ICN (SPG-ICN) that leverages a gossip protocol to self-configure and self-optimize the network using content providers. The simulation results demonstrate performance improvements compared to existing content dissemination schemes regarding packet overheads, data delivery delay, and network load. PubDate:

Pages: 16 - 22 Abstract: In the coming years, blockchain technologies will be used in a variety of industries, including telecommunications. In this article, due to strict governance of telecommunication infrastructure, we propose a blockchain supported architecture, based on a permissioned distributed ledger (PDL) scheme, for a network management and orchestration platform. The main goal is to create a trusted environment for multiple-stakeholders, such as Cloud Service Providers (CSPs), a Mobile Network Operator (MNO), Vertical Service Providers (SPs), Legal and Regulation Authorities, and Responsible Ministry so that the life cycle of automated vertical network services (e.g., instantiation, scaling, termination, and migration/reallocation) can be managed securely and transparently in a multi-cloud and multi-domain environment. The proposed approach is also validated with an experimental Industry 4.0 scenario using the Quorum blockchain network (BCN) to measure various performance metrics (e.g., number of transactions and blocks, and time to write) of various service orchestrator (SO)-related instantiation metrics. At the end of the article, we present the main discussions on the evaluation results and existing standardization efforts for the convergence of BCN, Management and Orchestration (MANO), and network services for a given telecommunication infrastructure.

Pages: 24 - 31 Abstract: As mobile systems for private use are gaining momentum, the area of network management automation is bound to attract renewed attention from standardization organizations and vendors. Prominent examples of tasks that would benefit from network automation tools are provisioning, diagnosing, and healing. Nevertheless, due to the various network and service providers as well as stakeholders involved in the deployment of a non-public mobile system, the success of such automation heavily depends on a smooth and effective interoperability among the components of the overall system. In this article, we review the state of the art of network operations, administration, and management in the context of mobile systems for non-public use, highlighting the differences with respect to traditional public networks. Then, we provide insights about the automated provisioning of an entire core network and a network slice subnet, both for private use, performed on a research testbed under continuous integration. Lastly, we propose a list of future challenges in this research area. PubDate:

Pages: 32 - 39 Abstract: The challenge of the expansion of millions of data-intensive Internet of Things (IoT) devices has led to more restriction data rates in the 5G wireless communication network. A web server can make use of network features and functions in a variety of capacities by detecting digital records of human and object behaviors from the Internet of Everything (IoE) for autonomous networks and devices. While web server appears to be a potential option when used in conjunction with next-generation wireless communications, such as 5G technology, it introduces new issues at the edge of the network. In this article, we discuss the progression in the development of wireless technologies beyond IoT (i.e., IoE for autonomous networks), while explaining the key enabling technologies beyond 5G networks. A web server-based edge architecture has been proposed for managing a large-scale of IoE devices based on 6G-enabled technology for autonomous networks and a smart resource distribution approach. The proposed system allocates receiving work-loads from IoE devices based on their flexible service requirements using the Boltzmann machines approach designed for energy-efficient communications. In addition, at the edge network, an Artificial Intelligence (AI)-driven method, namely the Support Vector Machines (SVM) retrieval model, is used to assess the data and obtain accurate results. The proposed system has been simulated and compared with some of the existing algorithms considering different use case scenarios. An overview of the emerging challenges of the proposed architecture has been discussed. PubDate:

Pages: 48 - 55 Abstract: Massive multiple-input multiple-output (MIMO) has been a key technology in 5G New Radio (NR) standard, which empowers significant system performance improvement in previous 5G NR Releases. To support higher data rate and multi-user simultaneous transmission in downlink, enhancement in massive MIMO is essential for NR Release 18 (Rel-18). In this article, we explore performance requirements, challenges, and potential technologies for MIMO enhancement. First, we summarize major performance requirements for MIMO in Enhanced Mobile Broadband scenario. Based on these requirements, we identify three critical challenges of MIMO enhancement for single transmission reception point (TRP) and multiple TRPs scheme, in which we highlight the promising coherent joint transmission (CJT) technique. For each challenge, we present specific description from requirement perspective and technique perspective, evaluate the pros and cons of potential solutions, and carry out simulations to illustrate the potential performance gain. Some insights on how to solve these challenges to enhance massive MIMO performance in NR Rel-18 are also provided. PubDate:

Pages: 56 - 63 Abstract: Network slicing is one of the most important enablers of an evolved network architecture for 5G networks that can support the challenging quality-of-service (QoS) requirements of future communication services. Network slicing is realized by technologies, such as software-defined networks, network function virtualization, and cloud radio access network (C-RAN) with packet-based fronthaul (P-FH) interfaces. However, it is still challenging to effectively support the diverse QoS requirements of network slices with limited FH link resources. To this end, FH payloads should be packetized in an appropriate way to apply transport differentiation provided in the P-FH interfaces since they are transported in a form of packets. In this article, we first comprehensively investigate the characteristics of the components of the FH payloads. Based on the investigation, we then design a packetization method that enables the P-FH interfaces to address the diverse QoS requirements by effectively applying their transport differentiation to the generated packets. Finally, we discuss open issues on realizing the P-FH interface in practice. PubDate:

Pages: 64 - 70 Abstract: Internet of Things (IoT) technologies, including drones, can efficiently capture industrial data, promoting the fourth industrial revolution, Industry 4.0. Moreover, as the 5G technologies evolve, Edge AI can push the AI programs from the remote cloud to the network edges close to end devices, enabling reliable and low-latency intelligent services. Compared with traditional applications, Industry 4.0 applications require more accuracy and lower latency. Most importantly, the robustness of Edge AI system is also critical for Industry 4.0 applications. In this work, we propose a robust Edge AI system for real-time industry 4.0 applications. Our proposed robust AI system can conduct model combination design and model deployment design based on the demands of applications, for example, application accuracy and application latency. Our system is also robust to physical system failures and resumes running intermediately when physical system failures occur. PubDate:

Pages: 72 - 82 Abstract: Internet of Things (IoT) applications are rapidly increasing. A broad range of low-power wide-area technologies have been developed in the Sub-1 GHz frequency bands to meet various application requirements. Massive IEEE 802.15.4g based systems have been deployed to provide low to moderate data rate capabilities. IEEE 802.11ah is designed to provide higher data rate capabilities than the data rates of IEEE 802.15.4g. In addition, other Sub-1 GHz band systems, including LoRa and SigFox, are also installed for applications with longer range communication need. There is considerable overlap in use cases targeted by these technologies. Due to the constrained spectrum allocation in the Sub-1 GHz frequency bands, these systems are likely to coexist. Therefore, the coexistence of heterogeneous Sub-1 GHz band wireless technologies becomes an issue to be addressed. Our measurements and simulations reveal significant interference among these systems. Previously the Sub-1 GHz band coexistence is not well addressed. Accordingly, IEEE New Standards Committee and Standard Board formed IEEE 802.19.3 Task Group in December 2018 to develop IEEE 802.19.3 standard for the coexistence of IEEE 802.11ah and IEEE 802.15.4g based systems to guide product deployment. IEEE 802.19.3 standard was published in April 2021. This article summarizes the Sub-1 GHz band systems, spectrum allocation, interference and noise measurements, coexistence issues, and coexistence recommendations presented in IEEE 802.19.3. It aims to introduce IEEE 802.19.3 standard to readers outside of IEEE 802 standard body and to application developers to raise awareness of potential coexistence issues and available coexistence techniques for the better system deployment. In addition, this article presents performance evaluation of the coexistence methods recommended in IEEE 802.19.3. PubDate:

Pages: 84 - 90 Abstract: Identity and access management is a core building block for the majority of web services. Cloud-based services, social webs, mobile apps, but also IoT-related services rely on identity management to provide a seamless and secure user experience. Transmitting and sharing sensitive information with other organizations always poses a security and privacy risk to all participating entities. One solution to tackle this problem is the principle of federated identity management (FIM). FIM is used to authenticate and authorize users across multiple organizations and platforms in order to obtain access to resources and services. The benefits of FIM are, for example, consistent data, reduced amount of sensitive information needed to be shared, as well as less passwords for the user to remember. Both predominant standards, Secure Assertion Markup Language (SAML) 2.0 and Open Authentication (OAuth) 2.0 with the authentication layer OpenID Connect, are in wide-spread practical use for at least a decade. However, these protocols were developed with different requirements in mind than nowadays present. This led to several extensions to tackle real-world problems, making it cumbersome to comply with every flavor. Also, Request for Comments (RFC) 8252 suggests that a native app opens a system browser for user authentication; consequently, new protocols are currently developed. For example, within Internet Engineering Task Force (IETF), Kantara Initiative, and OpenID Foundation, which (should) have three main goals in common: • Reducing the complexity in contrast to SAML 2.0 and OAuth 2.0. • Decreasing the amount of extensions and varieties found in the wild. Both help developers to comply with the standards and, consequently, increase the security. • Including edge and future use cases, making the protocols even more useful. This article gives insights into current developments and possible future paths. PubDate:
