Caching Scalable Videos in the Edge of Wireless Cellular Networks
Xuewei Zhang, Yuan Ren, Tiejun Lv +1
By pre-fetching popular videos into the local caches of edge nodes, wireless edge caching provides an effective means of reducing repeated content deliveries. To meet the various v…
Analysis and Optimization of Service Delay for Multi-quality Videos in Multi-tier Heterogeneous Network with Random Caching
Xuewei Zhang, Tiejun Lv, Yuan Ren +2
Aiming to minimize service delay, we propose a new random caching scheme in device-to-device (D2D)-assisted heterogeneous network. To support diversified viewing qualities of multi…
Learning-Based Multi-Channel Access in 5G and Beyond Networks with Fast Time-Varying Channels
Shaoyang Wang, Tiejun Lv, Xuewei Zhang +2
We propose a learning-based scheme to investigate the dynamic multi-channel access (DMCA) problem in the fifth generation (5G) and beyond networks with fast time-varying channels w…
Economical Caching for Scalable Videos in Cache-enabled Heterogeneous Networks
Xuewei Zhang, Tiejun Lv, Yuan Ren +3
We develop the optimal economical caching schemes in cache-enabled heterogeneous networks, while delivering multimedia video services with personalized viewing qualities to mobile…
Energy-Efficient Caching for Scalable Videos in Heterogeneous Networks
Xuewei Zhang, Tiejun Lv, Wei Ni +3
By suppressing repeated content deliveries, wireless caching has the potential to substantially improve the energy efficiency (EE) of the fifth generation (5G) communication networ…
