Analysis and Optimization of Cache-enabled Fog Radio Access Networks: Successful Transmission Probability, Fractional Offloaded Traffic and Delay

In this paper, the edge caching optimization problem in fog radio access networks (F-RANs) is investigated. Considering that fog access points (F-APs) can offer cooperation gain by jointly transmitting the same file or content diversity gain by concurrently transmitting the coded subfiles, we propose to use both joint transmission (JT) strategy and parallel transmission (PT) strategy to serve user...
