Multi-Tier Caching and Resource Sharing for Video Streaming in 5G Ultra-Dense Networks

Spectrum Sharing and Power Allocation Optimised Multihop Multipath D2D Video Delivery in Beyond 5G Networks

“…In [18], [19], D2D communications with caching were exploited to mitigate the workloads at not only the MBS but also the FBSs. These works consider the social relationship between the MUs [18] and the video encoding rates (video versions with different qualities) [19] to enhance the QoS and the caching performance.…”

“…In [18], [19], D2D communications with caching were exploited to mitigate the workloads at not only the MBS but also the FBSs. These works consider the social relationship between the MUs [18] and the video encoding rates (video versions with different qualities) [19] to enhance the QoS and the caching performance. When D2D communications with caching play an important role in a large scale of B5G/6G networks, a D2D caching system should be studied to gain an excellent caching performance [20].…”

“…[51]- [53]. Meanwhile, exhaustive algorithms can find the exact results, but causing computationally expensive and time-consuming, therefore not feasible to be applied to the real-world problems [18], [19]. Other promising methods such as dynamic programming, stochastic and game learning, greedy algorithm, and heuristic strategy, can provide lower complexity, but less accuracy [53].…”

Estratégia de Migração de Serviço baseada em Informações Contextuais em uma Arquitetura MEC

“…al. propôs um armazenamento em multicamadas e solução de compartilhamento de recursos que permite aos usuários móveis receberem versões de vídeo através de comunicações realizadas entre dispositivos, Estações-base Femto e Estações-base Macro em redes 5G ultra densas [Vo et al 2020]. Em particular, este trabalho considera recursos de downlink e recursos de armazenamento em células macro, femto e nós móveis, a fim de satisfazer o usuário móvel que solicita um vídeo específico.…”

UAV caching in 6G networks: A Survey on models, techniques, and applications

“…In static ground caching scenario, the caching techniques exploit available storage resource of mobile devices, SBSs, and MBSs to bring the requested contents closer to the EUs ( [6], [7] and references therein). In this way, the caching techniques can mitigate the congestion at the backhaul links of the MBSs and SBSs; serve the EUs high QoE (i.e., high hit rate, seamless playback, high playback quality, and low quality fluctuation) and URLLC; as well as conserve the caching storage, energy, and spectrum resources.…”
