A Small-Cell Caching System in Mobile Cellular Networks With LoS and NLoS Channels
Small-cell caching utilizes the embedded storage of small-cell base stations (SBS) to cache popular network contents, for the purpose of reducing duplicate transmissions in mobile networks and offloading the data traffic from macro-cell base stations.In this paper, we propose a random small-cell caching system, where each SBS randomly caches a subs
