A sequential approach with machine in ultra-dense 5G D2D networks

This work intends to resource allocation in ultra-dense networks for device-to-device (D2D) communication in the underlying cellular networks. This work proposes, particularly, many-to-many (M 2 ) approach with optimal power allocation (QALM 3 ). The effectiveness of the proposed work is verified by comparing its performance with one-to-many (O2M) approach by satisfying QoS data. The baseline objective of this paper is to maximize access rate (AR), energy efficiency (EE), and spectrum efficiency (SE). A novel algorithm is developed to solve this mixed integer non-linear programming problem (MINLP), which is NP hard problem to find optimal solutions. The simulation results shows the efficiency of the proposed algorithm and obtains the near-optimal system throughput and outperforms the one-to-many matching (O2M) approach in terms of EE (2–4)%, SE (2–10)%, and AR (60–100)%.
