Resources Allocation Algorithm for Multi-cell D2D Based on Noncooperative Game Theory
Abstract
In the mixed network which consists of cellular and device-to-device,there is a dynamic resources allocation problem in multi-cell D2 Dcommunication system when the interference between the users of intra-cell and inter-cell is considered.In this paper,we design a utilityfunction with interference control of the transmitted power of D2 Dusers after introducing the non-cooperative game theory and pricingmechanism.This utilityfunction not only considers the fairness but also the interference of the system.Then we demonstrate the existence and uniqueness of Nash equilibrium in a power control model,which indicate that the D2 Dusers can achieve a stable state after the games.Simulation results show that the proposed algorithm not only improves the fairness among the users,but also increases the throughputs and improves the performances of the system.
