Abstract: The rapid expansion of 5G networks and increasing user equipment (UEs) necessitate innovative approaches for improved energy efficiency. UE-to-UE communication is a promising solution, leveraging nearby UEs for efficient data transfer and reducing reliance on macro cells. We present the dynamic resource optimisation - green communication protocol (DRO-GCP) for 5G, using fuzzy logic (FL) to optimise energy-efficient UE-to-UE routing. DRO-GCP includes phases of network deployment, route optimisation, and D2D transmission. It calculates parameters such as UE speed, energy consumption, bandwidth occupancy, and connection quality using type-2 FL to identify over-utilised UEs. During transmission, the transmitting UE requests relay UEs, evaluates their responses, and selects optimal relays, ensuring reliable data transfer while minimising network overhead and CO₂ emissions. Simulations show DRO-GCP improves energy efficiency by 2.3-10.6% over existing methods, enhancing throughput, delay, energy consumption, and packet data ratio. This protocol offers a promising solution for energy-efficient 5G D2D communication.

Keywords: fuzzy logic; green communication; HetNets; UE-to-UE communication.
