Distributed Power Control for Energy Conservation in Hybrid Cellular Network with Device-to-Device Communication

The device-to-device (D2D) communication is the two terminals that can communicate directly and be controlled by the system. It can improve the efficiency of the cellular network communication greatly, but the interference caused by D2D communication has brought a series of problems to cellular networks’ management. In order to limit the interference of cross-layer and improve the utilization rate of hybrid cellular networks, we design a new kind of distributed power control (DPC) scheme. On the premise of meeting the requirements of quality of service, we further increased a biasing scheme into DPC, to avoid invalid power consumption, so as to realize the purpose of energy saving. The feasibility of the scheme is proved by the comparison and analysis of the simulation results.
