Abstract


Fog radio access networks (F-RANs) are the key promising architecture for next-generation wireless networks. This paper addresses the cache resource allocation problem in multi fog access points (F-APs) of F-RANs system. A linear programming (LP)-based problem is formulated for optimal allocation of the cache resource of multiple F-APs to the user equipments (UEs) to maximize the delivered contents while providing the minimum user data volume request and transmission delay constraints. Simulation results are shown to validate the proposed scheme.
