Abstract

A novel mobility-aware and energy-efficient coded caching provisioning strategy, Mobee, is proposed for a Cloud Radio Access Network (C-RAN). The placement of the Maximum-Distance Separable (MDS) encoded content at the Base Stations (BSs) is optimized to minimize the total energy consumption of the network comprising the transport and the caching energy consumptions. To account for user mobility, an estimation model for content-request rates at the BSs is derivedbased on the long-term content popularity and user-mobility pattern. The mobility-aware cache placement problem is then formulated as a convex optimization problem, which can be efficiently solved using standard solvers. Simulation results show that the proposed Mobee strategy significantly reduces the network energy consumption compared to traditional approaches.
