Small cell and device-to-device (D2D) communications can fulfill high-speed wireless communication in indoor industrial internet of things (IIoT) services and cell-edge devices. However, controlling interference is crucial for optimizing resource sharing (RS).To address this, we present an adaptive interference avoidance (IA) and mode selection (MS) framework that incorporates MS, channel gain factor (CGF), and powerallocation (PA) techniques to reduce reuse interference and increase the data rate of IIoT applications for 5G D2Denabled small cell (SC) networks. Our proposed approach employs a two-phase RS algorithm that minimizes the system's computational complexity while maximizing the network sum rate. First, we adaptively determine the D2D user mode for each cell based on the D2D pair channel gain ratios (CGR) of the cellular and reuse mode (RM). We compute the CGF for each cell with a D2D pair in RM to select the reuse partner. Then we determine the optimal distributed power for the D2D users and IoT-user equipment (IUEs) using the Lagrangian dual decomposition method to maximize the network sum rate while limiting the interference power. The simulation results indicate that our proposed approach can maximize system throughput and signal-to-interference plus noise ratio (SINR), reducing signaling overhead compared to other algorithms.

“…In [13], the problem of joint utility-based customized price and power control in multi-service wireless networks was investigated using S-modular theory. The authors of [14] made suboptimal solutions according to iterative methods for a resource allocation problem with partial fairness considering weighted sum throughput maximization in an orthogonal frequency-division multiple access system. 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].…”

Per-Flow Throughput Fairness in Ring Aggregation Network with Multiple Edge Routers

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.
