Fog RAN over General Purpose Processor Platform

Abstract

A novel Fog Radio Access Network architecture based on General Purpose Processor(GPP) Platform is proposed. Traditionally, people consider fog computing service as an independent computing unit in the Radio Access Network(RAN). Our design, on the contrary, considers both the computing resource for RAN and for fog computing application as an integrated computing resource pool. Based on the observation of the CPU load measurement on the Baseband Unit(BBU) testbed, we further scrutinize our proposed model and prove that it is feasible in the realistic RAN system.
