Multi-tier cooperative caching in fog radio access network by Yanxiang JIANG, Chengyu XIA

“…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.…”

Game-theoretical frequency reuse algorithm in Femtocell network by Xiong ZHOU, Sui-li FENG, Yue-hua DING, Yong-zhong ZHANG

“…A game-theoretical frequency reuse algorithm has been proposed for Femtocell network.Firstly,each Femtocell tries to get an available sub-band by sensing its radio circumstance.Then,inner-cluster frequency collisions are avoided by implementing a negotiation mechanism.Lastly,each cluster is regarded as a game player to get the largest utility by using its optimal strategy.Despite Femtocell base stations are randomly installed by users,the proposed method performs well in Femtocell network.Simulation results show that frequency collisions are dramatically reduced and the average capacity of Femtocells is considerably enhanced.…”

A Resource Allocation Scbeme Based on User's QoS in MIMO Relay System by Tao Guo, Youming Li, Peng Lei, Biao Ji, Chengcheng Li

“…For the resource allocation in OFDMA MIMO relay downlink system,a quality of service aware resource allocation scheme with low complexity under total power constraint was proposed.First,under the assumption of equal power allocation,a selective priority factor was chosen for the relay selecting and subcarrier allocation.The relay selection and subcarriers allocation were carried out depending on the priority factor.Then the optimal power allocation was implemented through convex optimization algorithm.Numerical results show that the proposed scheme can not only achieve the higher capacity of system,but also guarantee the quality of service for each user.…”
