Abstract: The increasing number of connected devices in 5G HetNets emphasises the need for energy-efficient communication. UE-to-UE communication, focusing on energy-efficient routing, handover, and optimal UE selection while maintaining throughput, is crucial. We introduce the Dynamic Resources Optimisation and Interference Management-based Green Communication Protocol (DROIM-GCP) using type-2 fuzzy logic. DROIM-GCP operates in two phases: resource optimisation and interference management. In resource optimisation, UEs periodically measure Bandwidth Utilisation Factor, Link Reliability Factor, Energy Utilisation Factor, and Velocity Normalisation Factor. These inputs are processed via fuzzy logic to select the optimal UE for transmission. In interference management, handover candidates are identified based on RSSI, Velocity Normalisation Factor, Energy Utilisation Factor, and Link Reliability Factor. Target femtocells are selected using Bandwidth Utilisation Factor and Channel Occupancy. DROIM-GCP aims to maximise throughput and packet data rate while minimising energy consumption and delay. Simulations show it outperforms existing methods, improving energy efficiency by 6.25-12.79%.

Keywords: green communication; heterogeneous network; handover; UE-to-UE communication; resource optimisation; type-2 fuzzy logic.
