摘要

针对边缘缓存和雾无线接入技术中降低后传链路负载的问题，提出了一种雾无线接入网中的多层协作缓存方法。考虑网络架构、文件流行度估计、链路容量等因素，将相关的优化问题分解为每个层中缓存布置的背包问题，并分别使用贪心算法求解。仿真结果表明，所提出的多层协作缓存方法能够有效降低后传链路负载，同时具有较高的缓存命中率。

Abstract

Aiming at the problem of reducing the load of the backward link in the edge buffer and fog wireless access network technology

a multi-tier cooperative caching scheme in F-RAN was proposed to further reduce the backhaul traffic load.In particular

by considering the network topology

content popularity prediction and link capacity

the optimization problem was decomposed into knapsack subproblems in multi-tiers

and effective greedy algorithms were proposed to solve the corresponding subproblems.Simulation results show that the proposed multi-tier cooperative caching scheme can effectively reduce the backhaul traffic and achieve relatively high cache hit rate.
