Device-to-device caching for video content delivery
In this study, we construct a detailed simulation model in order to quantify the benefits of device-to-device (D2D) caching for video content delivery. Simulation model involves caches at the evolved packet core, radio access network (RAN) and end user devices. We compare the bandwidth cost savings for different caching strategies at the EPC, RAN and devices and find the best joint strategy.
