Network‐Controlled Repeaters and Deep Q‐Learning for Energy‐Efficient 6G Routing: A Lifelike Simulation Framework Using GNS3

Journal of Engineering, Volume 2026, Issue 1, 2026.
In the forthcoming 6G era, network infrastructure must achieve unprecedented energy efficiency, adaptability, and ultralow latency. This paper proposes a novel Deep Q‐Network (DQN)‐based routing framework that leverages network‐controlled repeaters (NCRs) to optimize routing paths dynamically.

A Distributed Multi-Agent RL-Based Autonomous Spectrum Allocation Scheme in D2D Enabled Multi-Tier HetNets

IEEE Access, 2019
Multi-tier heterogeneous networks (HetNets) and device-to-device (D2D) communication are vastly considered in 5G networks. The interference mitigation and resource allocation in the D2D enabled multi-tier HetNets is a cumbersome and challenging task that

Vehicular‐to‐Everything (V2X) Communication Using 5G NR for Autonomous Vehicles

Journal of Engineering, Volume 2026, Issue 1, 2026.
This paper explores the fundamental issue to conflicting performance requirements in 5G New Radio (5G NR) vehicle‐to‐everything (V2X) communications for autonomous driving applications. Unlike the previous literature where most of its studies consider single performance measures in a fixed or simplified environment, the proposed system presents a ...

On the Local Delay and Energy Efficiency of HetNets with User Mobility [PDF]

, 2018
With the development of fifth generation (5G) communications systems, heterogeneous networks (HetNets) have become a research hotspot. However, most of the existing work assumes that the user is static in HetNets.

Network switching strategy for energy conservation in heterogeneous networks. [PDF]

PLoS ONE, 2017
In heterogeneous networks (HetNets), the large-scale deployment of small base stations (BSs) together with traditional macro BSs is an economical and efficient solution that is employed to address the exponential growth in mobile data traffic.

Energy Efficient Resource Allocation for H-NOMA Assisted B5G HetNets

IEEE Access, 2022
The resource allocation solution offered based on non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA) schemes are sub-optimal to address the challenging quality of service (QoS) and higher data rate viz-a-viz energy efficiency (EE)

⁠Performance Enhancement of Cell Edge Users in NOMA Based Systems Using Fractional Frequency Reuse

Journal of Sensors, Volume 2026, Issue 1, 2026.
Nonorthogonal multiple access (NOMA) causes significant performance loss for cell‐edge users due to strong intercell interference and fairness constraints under dense deployments. Although fractional frequency reuse (FFR) to improve dependability, especially for cell‐edge users, is widely researched, joint optimization with SINR‐based zoning and NOMA ...

A Sub‐Optimum Algorithm for Turning On/Off Co‐Channel Access Points in Ultra‐Dense Networks

Engineering Reports, Volume 7, Issue 11, November 2025.
In the proposed seven‐step Kuhn–Munkres–based resource allocation algorithm, users are initially assigned to access points that support higher data rates while accounting for interference from all access points. Next, only the interference from the selected access points is considered to identify users connected to these access points who meet the ...
