“…These methods have been used in appropriate areas taking into account their pros and cons. Network selection methods and resource allocation methods based on the idea of the PF method have been proposed [19]. In PF-based network selection, the predictive throughput is also calculated at the backbone sites.…”

To process increasing data traffic, one of the most effective solutions is data offloading. Processing data traffic in heterogeneous networks (HetNets) based on loaded traffic conditions improves the user throughput. In this case, user traffic needs to be divided taking account of the difference in the transmission rate among networks. When a macro base station (BS) provides wireless resources for user equipment (UE) of good channel quality near the macro BS, higher user throughput is expected. However, at the macro cell edge, the transmission performance of UEs in a micro cell deteriorates. To reduce this inconvenience, by processing the loaded traffic appropriately using a macro BS and micro BS, we can obtain higher user throughput. This paper proposes wireless resource allocation based on loaded traffic conditions and the position of BSs with ON-OFF switching according to the channel quality in HetNets. Simulation results show the effectiveness of the proposed method, especially when the data loss ratio of the macro cell is low and that of micro cells is high. The proposed method is effective for a damage-resistant system against natural disasters and an automatic driving system in an intelligent transport system (ITS).

“…For joint users' uplink transmission power and data rate allocation in multi-service two-tier femtocell networks, a distributed and iterative algorithm for computing the desired Nash Equilibrium was introduced [15]. In [16], a user association method to maximize the downlink system throughput in a cellular network was proposed. To achieve per-flow fairness and bufferbloat avoidance in ring aggregation networks, N Rate N + 1 Color Marking (NRN + 1CM) was proposed [17][18][19].…”

Ring aggregation networks are often employed by network carriers because of their efficiency and high fault tolerance. A fairness scheme is required in ring aggregation to achieve per-flow throughput fairness and bufferbloat avoidance, because frames are forwarded along multiple ring nodes. N Rate N + 1 Color Marking (NRN + 1CM) was proposed to achieve fairness in ring aggregation networks consisting of Layer-2 Switches (SWs). With NRN + 1CM, frames are selectively discarded based on color and the frame-dropping threshold. To avoid the accumulation of a queuing delay, frames are discarded at upstream nodes in advance through the notification process for the frame-dropping threshold. However, in the previous works, NRN + 1CM was assumed to be employed in a logical daisy chain topology linked to one Edge Router (ER). The currently available threshold notification process of NRN + 1CM cannot be employed for ring networks with multiple ERs. Therefore, this paper proposes a method for applying NRN + 1CM to a ring aggregation network with multiple ERs. With the proposed algorithm, an SW dynamically selects the dropping threshold to send in order to avoid excess frame discarding. The performance of the proposed scheme was confirmed through computer simulations.
