Research on Power Control Algorithm Based on Non Cooperative Game in D2D Communication

The introduction of D2D improves the performance of communication systems but introduces interference management problems. The algorithm adopts a noncooperative game framework, introduces a dynamic cost mechanism, suppresses the common-channel interference within the system, analyses that the solution of the Nash equilibrium in the process of this game exists and is unique, and gives a distributed power adjustment algorithm for D2D users to engage in rational competition under the noncooperative game model. Theoretical analyses and emulation results show that the arithmetic greatly improves the throughput of the system while effectively controlling the interference between the communicating users within the system.
