Enhanced Distance-Based Resource Allocation for Spectrum Utilization an

Abstract

The rapid development of 6G networks presents
challenges in effectively allocating resources for device-to-device (D2D)
communication, especially in dense and dynamic networks. This paper
presents an enhanced distance-based resource allocation (EDBRA)
scheme to improve spectrum utilization and fairness for D2D
communication in 6G networks. The EDBRA dynamically allocates
resources using distance and the signal-to-interference-plus-noise ratio
(SINR). An intelligent power adjustment and adaptive resource
allocation are applied to prevent SINR cliff effects and reduce edge-user
starvation. The proposed scheme significantly outperforms traditional
baseline resource allocation methods regarding spectrum utilization and
fairness. Experimental results show a 40% improvement in utilization
and 67% gains in fairness compared to baselines, with 84% of users
exceeding the 3 dB SINR threshold at cell edges. This paper validates
EDBRA as a robust solution for 6G D2D networks, offering substantial
spectrum utilization, fairness, and reliability improvements in dense,
highly dynamic environments.
