“…The experimental results show that the method can effectively improve the throughput and access rate of cellular networks. The authors in [8] describe a communication process for load balancing between BSs. Users of the overloaded BS are relayed to the nearby idle BSs by the two-hop relay communication.…”

“…Here we introduce the Jains Fairness Index mentioned in [14]. The data offloaded to each idle BS can be expressed as follows: (8) The fairness metric is expressed as follows: (9) The value of is between 0 and 1, and the larger the , the more balancing the traffic offloaded to each IBS. Moreover, we set fairness threshold , and only when is greater than Jth, the traffic offloading process is balancing.…”

Device-to-device (D2D) communication is a promising technique for traffic offloading in next-generation cellularsystems, in response to the sharp increase in traffic and unevendistribution. In this paper, in the case of meeting the user's delay, we propose a multi-hop D2D traffic offloading scheme to expand the range of traffic offloading. In consideration of the load balancing problem, we introduce load fairness of Base Stations to restraint the traffic that is offloaded to each BS. And, based on the constraints of delay and fairness, we formulate an optimization model that maximizes the range of offloading. We also proposed joint algorithm to achieve traffic offloading. And simulation results show that our scheme can further expand the range of traffic offloading under the condition of ensuring load fairness.
