Sharing Distributed and Heterogeneous Resources toward End-to-End 5G Networks: A Comprehensive Survey and a Taxonomy

Abstract

Regardless of the context to which it is applied, sharing resources is well-recognized for its considerable benefits. Since 5G networks will be service-oriented, on-demand, and highly heterogeneous, it is utmost important to approach the design and optimization of the network from an end-to-end perspective. In addition, in order to ensure end-to-end performance, this approach has to entail both wireless and optical domains, altogether with the IoT, edge, and cloud paradigms which are an indispensable part of the 5G network architecture. Shifting from the exclusive ownership of network resources toward sharing enables all participants to cope with stringent service requirements in 5G networks, gaining significant performance improvements and cost savings at the same time. The main objective of this paper is to survey the literature on resource sharing, providing an in-depth and comprehensive perspective of sharing by recognizing the main trends, the techniques which enable sharing, and the challenges that need to be addressed. By providing a taxonomy which brings the relevant features of a comprehensive sharing model into focus, we aim to enable the creation of sharing models for more efficient future communication networks. We also summarize and discuss the relevant issues arising from network sharing, that should be properly tackled in the future.

Intelligent Media Forensics and Traffic Handling Scheme in 5G Edge Networks

“…ML takes a crucial responsibility in the classification of different applications, while E2E NS is required to differentiate the behaviors of user devices, RRH, network resources, and media contents [16][17][18][19]. Different media requires different security and QoS obligations to ensure trustful E2E communication and satisfy the QoS requirement; therefore, the slicing of different media contents (e.g., media forensics) is mandatory [20]. 5G/6G edge environments consist of insufficient computing resources; therefore, the lightweight media inspection methods have to be considered.…”

Convergence of Wireless and Optical Network in Future Communication Network

“…To enables this SDO has been in an optical network. This can be done through the construction of application-specific protocol stacks out of small reusable services [1].…”

“…Over the year, the number of connected devices (wirelessly and wired) is everincreasing, will reach 13 billion by 2023 [1]. To support these always-connected devices, the demand for high speed, high reliability, low-latency, low-cost, dense connectivity, different types of mobility needs, and heterogeneous connectivity is escalating, which forced the telecommunications industry to enter into a new era of the future communication network (FCN) [2].…”

Network Service and Resource Orchestration: A Feature and Performance Analysis within the MEC-Enhanced Vehicular Network Context

“…Soua et al [6] and Taleb et al [9] also discuss that this high heterogeneity in services, resources, technologies, and cloud infrastructure induce severe challenges to meet QoS and QoE requirements, and to maintain service continuity. Also, this heterogeneous nature makes the resource allocation [18] and management even more complex. Therefore, there is a need for more sophisticated framework for service and resource management, unifying networking and cloud orchestration [6,9].…”
