| In view of the abundant vegetation and mountainous hills in the plateau and mountainous areas, which cause serious path loss
to communication users, increase the energy consumption of communication systems. This paper proposes an optimization algorithm
based on energy efficiency (EE). First, the multi-peak diffraction model is used to simulate the transmission loss of radio waves in the
plateau and mountainous areas. Under the premise of ensuring the quality of server (QoS) for communication users, the total energy
efficiency of the D2D user equipment in the system is maximized, and the optimization problem is decomposed into power. Two subproblems of control and channel selection are solved. Secondly, the Lagrangian duality and Dinkbach algorithm are used to jointly solve
the power control. Finally, on the basis of power control, the Gale-Shapley matching algorithm is used to achieve channel matching. The
simulation results show that compared with the existing algorithms, the proposed algorithm can effectively restrain co-channel
interference, increase the utilization of channel resources in the system, improve the energy efficiency of the system, reduce system
energy consumption, and improve system performance. |
