A comparison of power allocation mechanisms for 5G D2D mobile communication networks

The ever-increasing demands for higher data trans-mission speeds, channel reliability and less energy consumption push the scientific community to discover new methods to manage resources of modern networks, without degrading the quality of communications. Modern cellular systems of the fifth generation (5G) are internationally recognized for their excellent performance and for the innovative technologies that they apply. The Device-to-Device (D2D) protocol has been established among the technologies of 5G, for the fast and secure direct connections between terminals and the overall capabilities that it provides. The protocol is able to offload the network and reorganize connections in order to save system resources, while also supporting decentralized communications. The present work aims to highlight the importance of D2D communications in 5G cellular networks by assessing the performance of four well known energy resource allocation mechanisms in scenarios with environmental constraints. Results of our simulations showcase that D2D Communication technologies can improve the energy efficiency and increase the total throughput output of existing cellular networks.
